20070224	Minor update to the initialization of the ns16550 in
		machine_walnut.c, to allow that machine type to boot with the
		new interrupt system (although it is still a dummy machine).
		Adding a wdc at 0x14000000 to machine_landisk.c, and fixing
		the SCIF serial interrupts of the SH4 cpu enough to get
		NetBSD/landisk booting from a disk image :-)  Adding a
		preliminary install instruction skeleton to guestoses.html.
20070306	Adding SH-IPL+G PROM emulation, and also passing the "end"
		symbol in r5 on bootup, for Landisk emulation. This is enough
		to get OpenBSD/landisk to install :)  Adding a preliminary
		install instruction skeleton to the documentation. SuperH
		emulation is still shaky, though :-/
20070307	Fixed a strangeness in memory_sh.c (read/write was never
		returned for any page). (Unknown whether this fixes any actual
		problems, though.)
20070308	dev_ram.c fix: invalidate code translations on writes to
		RAM, emulated as separate devices. Linux/dreamcast gets
		further in the boot process than before, but still bugs out
		in userland.
		Fixing bugs in the "stc.l gbr,@-rN" and "ldc.l @rN+,gbr" SuperH 
		instructions (they should NOT check the MD bit), allowing the
		Linux/dreamcast Live CD to reach userland correctly :-)
20070310	Changing the cpu name "Alpha" in src/useremul.c to "21364" to
		unbreak userland syscall emulation of FreeBSD/Alpha binaries.
20070314	Applying a patch from Michael Yaroslavtsev which fixes the
		previous Linux lib64 patch to the configure script.
20070315	Adding a (dummy) sun4v machine type, and SPARC T1 cpu type.
20070316	Creating a new directory, src/disk, and moving diskimage.c
		to it. Separating out bootblock loading stuff from emul.c into
		new files in src/disk.
		Adding some more SPARC registers.
20070318	Preparing/testing for a minirelease, 0.4.4.1.

80 <h3>General notes on running "guest OSes":</h3>
81
82 The emulator works well enough to run complete operating systems. These
83 are often refered to as <i>guest</i> operating systems, in contrast to the
84 <i>host</i> operating system which the emulator is running under.
85
86 <p>Although it is possible to let a guest OS access real hardware, such as
87 harddisks, it is much more flexible and attractive to simulate harddisks
88 using files residing in the host's filesystem. On Unix-like systems, files
89 may contain holes, which makes this really simple. To the guest operating
90 system, the harddisk image looks and acts like a real disk.
91
92 <p>The version numbers of the various operating systems were the latest
93 versions that worked satisfactory with GXemul at the time this page was
94 updated; if new versions have been released since then, they might work as
95 well.
96
97 <p>In addition to the "working" guest operating systems listed above,
98 you might find the following information interesting:

113 <p><b><font color="#ff0000">NOTE:</b>
114 Some of these sections may not be relevant to this
115 specific release of GXemul,</font> for example some of these
116 modes may be legacy modes that worked before but not any longer,
117 or are not yet working but could be in the future.
118
119 <p>Some operating systems are listed with a version number <i>less</i>
120 than what was available at the time of this GXemul release (e.g.
121 NetBSD/prep). The reasons for this is because of incompleteness in
122 GXemul's machine, device, and/or processor implementations.

132 <h3>NetBSD/pmax:</h3>
133
134 <p><a href="http://www.netbsd.org/Ports/pmax/">NetBSD/pmax</a> was the
135 first guest OS that could be
136 <a href="http://mail-index.netbsd.org/port-pmax/2004/04/18/0000.html">installed</a>
137 onto a disk image in GXemul. The device emulation of the DECstation
138 5000/200 is reasonably complete; it should be enough to emulate a
139 networked X-windows-capable workstation.
140
141 <p>NetBSD/pmax 1.6.2 works perfectly with X out-of-the-box. Unfortunately,
142 newer NetBSD releases have changed slightly, and X does not work straight
143 away with NetBSD 2.x and 3.x. It seems that this has to do with NetBSD
144 switching console system to "WSCONS" somewhere between 1.6.2 and 2.0.
145
146 <p>What this means is that if you want to use emulated X11, then you need
147 to run NetBSD 1.6.2. At the time of writing this, 4.0_BETA snapshots work
148 fine too, but 4.0 isn't released yet. If you feel that you only need
149 serial-console emulation, then choose 3.1.
150
151 <p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
152 <a href="20050317-example.png"><img src="20050317-example_small.png"></a>
153
154 <p>To install NetBSD/pmax onto a harddisk image in the emulator,
155 follow these instructions:
156
157 <p><ol start="1">
158 <li>Create an empty harddisk image, which will be the root disk
159 that NetBSD installs itself onto:<pre>
160 <b>dd if=/dev/zero of=nbsd_pmax.img bs=1024 count=1 seek=3000000</b>
161
162 </pre>
163 </ol>
164
165 <p>
166 From this point, there are two separate ways to continue the installation.
167 You can either download a CD-ROM iso image (and let the installation
168 program copy files from the CD-ROM image to the harddisk image), or you
169 can install via ftp. For an installation from a CD-ROM image, follow these
170 steps:
171 <p>
172 <ol start="2">
173
174 <li>Download a NetBSD CD-ROM iso image:<pre>
175 <a href="ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-archive/iso/1.6.2/pmaxcd.iso">ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-archive/iso/1.6.2/pmaxcd.iso</a>
176 or
177 <a href="ftp://ftp.netbsd.org/pub/NetBSD/iso/3.1/pmaxcd-3.1.iso">ftp://ftp.netbsd.org/pub/NetBSD/iso/3.1/pmaxcd-3.1.iso</a>
178
179 </pre>
180 <li>Start the emulator like this:<pre>
181 <b>gxemul -e 3max -d nbsd_pmax.img -d bc:pmaxcd-3.1.iso</b>
182 (or <b>pmaxcd.iso</b>)
183 </pre>
184 and proceed like you would do if you were installing NetBSD on a real
185 DECstation. Remember to choose <tt>vt100</tt> as your terminal
186 type, and not <tt>rcons</tt>.
187 </ol>
188 <p>
189 For an ftp install, substitute steps 2 and 3 above with these:
190 <p>
191 <ol start="2">
192
193 <li>Download a NetBSD pmax INSTALL kernel:<pre>
194 <a href="ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-archive/NetBSD-1.6.2/pmax/binary/kernel/netbsd-INSTALL.gz">ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-archive/NetBSD-1.6.2/pmax/binary/kernel/netbsd-INSTALL.gz</a>
195 or
196 <a href="ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-3.1/pmax/binary/kernel/netbsd-INSTALL.gz">ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-3.1/pmax/binary/kernel/netbsd-INSTALL.gz</a>
197
198 </pre>
199 <li>Start the emulator like this:<pre>
200 <b>gxemul -e 3max -d nbsd_pmax.img -O netbsd-INSTALL.gz</b>
201 </pre>
202 and proceed like you would do if you were installing NetBSD on a real
203 DECstation. Remember to choose <tt>vt100</tt> as your terminal
204 type, and not <tt>rcons</tt>. Suitable networking parameters are as
205 follows:<pre>
206 Which device shall I use? [le0]: <b>le0</b>
207 ..
208 Your DNS domain: <b>mydomain.com</b>
209 Your host name: <b>foo</b>
210 Your IPv4 number: <b>10.0.0.1</b>
211 IPv4 Netmask [0xff000000]: <b>0xff000000</b>
212 IPv4 gateway: <b>10.0.0.254</b>
213 IPv4 name server: <b>10.0.0.254</b>
214 </pre>
215 (If using 10.0.0.254 as the nameserver fails, then try entering the
216 IP number of a real-world nameserver instead.)
217 </ol>
218
219 <p>If you want to use a graphical framebuffer during the install, you can
220 add <b><tt>-X -Y2</tt></b> to the command line, and choose <tt>rcons</tt>
221 instead of <tt>vt100</tt> when prompted with which terminal type to use.
222 (By just using <tt><b>-X</b></tt>, you will get a full-size framebuffer
223 window.)
224
225 <p>When the installation is finished, the following command should start
226 NetBSD from the harddisk image:<pre>
227 <b>gxemul -e 3max -d nbsd_pmax.img</b>
228 </pre>
229
230 <p>If you installed NetBSD/pmax 1.6.2, or 4.0_BETA, then try the
231 following to start with a framebuffer:<pre>
232 <b>gxemul -X -e 3max -d nbsd_pmax.img</b>
233 </pre>
234 and log in as <tt>root</tt> and type <tt>startx</tt> to start X windows.

246
247 It is possible to install and run an old version of <a
248 href="http://www.netbsd.org/Ports/arc/">NetBSD/arc</a>
249 on an emulated Acer PICA-61 in the emulator.

254
255 <p>
256 To install NetBSD/arc 1.6.2 from a CDROM image onto an emulated
257 harddisk image, follow these instructions:
258
259 <p>
260 <ol start="1">
261 <li>Create an empty harddisk image, which will be the root disk
262 that NetBSD installs itself onto:<pre>
263 <b>dd if=/dev/zero of=nbsd_arc.img bs=1024 count=1 seek=2000000</b>
264
265 </pre>
266 <li>Download a NetBSD/arc 1.6.2 CDROM image, and a generic NetBSD/arc
267 kernel:<pre>
268 <a href="ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-archive/iso/1.6.2/arccd.iso">ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-archive/iso/1.6.2/arccd.iso</a>

270
271 </pre>
272 <li>Start the emulator using this command line:<pre>
273 <b>gxemul -e pica -x -d nbsd_arc.img -d bc:arccd.iso -j arc/binary/kernel/netbsd.RAMDISK.gz</b>
274
275 </pre>
276 (Try removing <tt>-x</tt> if you have problems with the xterm.)
277 <p>
278 <li>From now on, you have to use your imagination, as there is no
279 automatic installation program for NetBSD/arc 1.6.2. Here are
280 some tips and hints on how you can proceed with the install:
281 <p><table border="0"><tr><td><tt>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</tt></td><td><pre>
282 <b>mount /dev/cd0a /mnt2
283 disklabel -i -I sd0</b> (for example 'a', '4.2BSD', '1c',
284 '700M', 'b', 'swap', '701M', '$', 'P', 'W', 'y', and 'Q')
285 <b>newfs /dev/sd0a
286 mount /dev/sd0a /mnt
287 cd /mnt
288 for a in /mnt2/arc/binary/sets/*.tgz; do echo $a; tar xzpf $a; done
289 cd dev; sh MAKEDEV all
290 cd ../etc; echo "rc_configured=YES" &gt;&gt; rc.conf
291 cat > /mnt/etc/fstab
292 /dev/sd0a / ffs rw 1 1

295 <b>cd /; umount /mnt; umount /mnt2
296 halt</b>
297 </pre></td></tr></table>
298 </ol>
299
300 <p>You can now use the generic NetBSD/arc kernel to boot from the harddisk
301 image, using the following command:<pre>
302 <b>gxemul -e pica -x -d nbsd_arc.img netbsd-GENERIC.gz</b>
303
304 </pre>
305
306 <p>When asked for "<tt>root device: </tt>", enter <b><tt>sd0</tt></b>.

316 <h3>NetBSD/hpcmips:</h3>
317
318 It is possible to install <a
319 href="http://www.netbsd.org/Ports/hpcmips/">NetBSD/hpcmips</a> onto a disk
320 image, on an an emulated MobilePro 770 or 800. (MobilePro 780 and 880 might
321 work too, but I don't test those for every release of the emulator. They
322 have unaligned framebuffers, and run a bit slower.)

331 These instructions show an example of how to install
332 NetBSD/hpcmips on an emulated MobilePro 770:

344
345 </pre>
346 <p>
347 <li>Start the installation like this:<pre>
348 <b>gxemul -e mobilepro770 -X -d nbsd_hpcmips.img -d b:hpcmipscd-3.1.iso -j hpcmips/installation/netbsd.gz</b>
349
350 </pre>
351 and proceed like you would do if you were installing NetBSD on a real
352 MobilePro 770. (Install onto wd0, choose "Use entire disk" when
353 doing the MBR partitioning, and choose to install from CD-ROM.)
354 </ol>
355
356 <p>
357 If everything worked, NetBSD should now be installed on the disk image.
358 Use the following command line to boot the emulated hpcmips machine:<pre>
359 <b>gxemul -e mobilepro770 -X -d nbsd_hpcmips.img netbsd-GENERIC.gz</b>
360
361 </pre>
362
363 <p>When you have logged in as <tt>root</tt>, you can use <tt>startx</tt> to
364 start X Windows, but there is no mouse support yet so only keyboard input
365 is available. This makes it a bit akward to use X.

376 <h3>NetBSD/cobalt:</h3>
377
378 <a href="http://www.netbsd.org/Ports/cobalt/">NetBSD/cobalt</a> is tricky
379 to install, because the Cobalt machines were designed for Linux, and not
380 very flexible. There is no traditional INSTALL kernel for NetBSD/cobalt.
381 One way to install the NetBSD/cobalt distribution onto a disk image is to
382 do it from another (emulated) machine.
383

795 For example, when NetBSD says "<tt>nfs_boot: trying DHCP/BOOTP</tt>",
796 there will be a long pause, even on a very fast host machine. The reason
797 for this is mostly because the emulator doesn't deal with timing issues

817 To install NetBSD/cats onto a disk image, follow these instructions:
818
819 <p>
820 <ol start="1">
821 <li>Create an empty harddisk image, which will be the root disk
822 that you will install NetBSD/cats onto:<pre>
823 <b>dd if=/dev/zero of=nbsd_cats.img bs=1024 count=1 seek=3000000</b>
824
825 </pre>
826 <li>Download the NetBSD/cats 3.1 ISO image and the generic and install kernels:<pre>
827 <a href="ftp://ftp.netbsd.org/pub/NetBSD/iso/3.1/catscd-3.1.iso">ftp://ftp.netbsd.org/pub/NetBSD/iso/3.1/catscd-3.1.iso</a>

830
831 </pre>
832 <p>
833 <li>Start the installation like this:<pre>
834 <b>gxemul -XEcats -d nbsd_cats.img -d catscd-3.1.iso netbsd.aout-INSTALL.gz</b>
835
836 </pre>
837 and proceed like you would do if you were installing NetBSD on a real
838 CATS from CDROM.
839 </ol>
840
841 <p>Alternatively, to install from FTP, you can skip downloading the ISO,
842 and start the install without <tt>-d catscd-3.1.iso</tt>. Suitable network
843 settings are IP 10.0.0.1, gateway/default route 10.0.0.254, netmask
844 255.0.0.0, nameserver 10.0.0.254.
845
846 <p>If everything worked, NetBSD should now be installed on the disk image.
847 Use the following command line to boot the emulated CATS machine:<pre>
848 <b>gxemul -XEcats -d nbsd_cats.img netbsd.aout-GENERIC.gz</b>

861
862 <a href="http://www.netbsd.org/Ports/evbarm/">NetBSD/evbarm</a> can
863 run in GXemul on an emulated IQ80321 evaluation board.

867
868 <p>It is tricky to install, because there is (as far as I know) no INSTALL
869 kernel. One way to install the NetBSD/evbarm distribution onto a disk
870 image is to install the files using another (emulated) machine.
871
872 <p>The following instructions will let you install NetBSD/evbarm onto a disk
873 image, from an emulated CATS machine:
874
875 <p>
876 <ol>
877 <li>Install NetBSD/cats 3.1 according to instructions
878 <a href="#netbsdcatsinstall">further up on this page</a>.
879 <p>
880 <li>Create an empty harddisk image, which will be the disk image
881 that you will install NetBSD onto:<pre>
882 <b>dd if=/dev/zero of=nbsd_iq80321.img bs=1024 count=1 seek=999000</b>
883
884 </pre>
885 <li>Download an IQ80321 kernel with wdc support, and the 2.1 ISO image:<pre>

888
889 </pre>
890 <p>
891 <li>The first step is to copy the distribution .tgz files onto the CATS
892 machine's harddisk. Start the CATS machine like this:<pre>
893 <b>gxemul -XEcats -d nbsd_cats.img -d evbarmcd.iso netbsd.aout-GENERIC.gz</b>
894
895 </pre>and execute the following commands as <tt>root</tt>:
896 <p><table border="0"><tr><td><tt>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</tt></td><td><pre>
897 <b>mount /dev/cd0a /mnt; cd /root; cp /mnt/evbarm/binary/sets/[bcegmt]* .
898 sync; halt</b>
899 </pre></td></tr></table>
900 <p>
901 <li>Now let's extract the files onto the IQ80321's disk image. Start the
902 CATS machine again, with the following command line:<pre>
903 <b>gxemul -XEcats -d nbsd_cats.img -d nbsd_iq80321.img netbsd.aout-GENERIC.gz</b>
904
905 </pre>and execute the following commands as <tt>root</tt>:

907 <b>disklabel -I -i wd1</b>
908 (enter suitable commands, e.g. <i>a, 4.2BSD, 1c, 750M, b,

910 <b>newfs /dev/wd1a; mount /dev/wd1a /mnt; cd /mnt; sh

945 <p>There is no INSTALL ramdisk kernel, so one way to install the

950
951 <p>
952 <ol>

990 <b>gxemul -X -E netwinder -d nbsd_netwinder.img netbsd-GENERIC.gz</b>
991 </pre>
992
993 <p>This will result in a 1024x768 framebuffer. Add <tt>-Y2</tt> to the
994 command line if you want to scale it down to 512x384.
995
996 <p>Note: The installation instructions above create a filesystem
997 <i>without</i> a disklabel, so there is only one ffs partition and no
998 swap. You will need to enter the following things when booting with the
999 generic kernel:<pre>
1000 root device (default wd0a): <b>wd0c</b>
1001 dump device (default wd0b): <i>(just press enter)</i>
1002 file system (default generic): <i>(just press enter)</i>
1003 init path (default /sbin/init): <i>(just press enter)</i>
1004 </pre>
1005
1006 <p>Known bugs/problems:
1007
1008 <ul>
1009 <li>There is a long delay when starting up NetBSD/netwinder
1010 (several seconds even on a very fast host machine),
1011 so you need to be patient.
1012 <li>There is a minor bug in the keyboard device, so you need to
1013 press a key (any key) before typing wd0c.
1014 <li>When halting/rebooting NetBSD/netwinder, the emulator
1015 prints a message saying something about an internal
1016 error. This doesn't matter; ignore the message.

1235 <p>
1236 OpenBSD/pmax died at release 2.8 of OpenBSD, so you should be
1237 aware of the fact that this will not give you an up-to-date OpenBSD
1238 system.
1239
1240 <p>
1241 Following these instructions <i>might</i> work. If not, then use
1242 common sense and imagination to modify them as you see fit.
1243
1244 <p>
1245 <ol>
1246 <li>Create an empty harddisk image, which will be the root disk
1247 that OpenBSD installs itself onto:<pre>
1248 <b>dd if=/dev/zero of=obsd_pmax.img bs=1 count=512 seek=900000000</b>
1249
1250 </pre>
1251 <li>Download the entire pmax directory from the ftp server: (approx. 99 MB)<pre>
1252 <b>wget -r <a href="ftp://ftp.se.openbsd.org/pub/OpenBSD/2.8/pmax/">ftp://ftp.se.openbsd.org/pub/OpenBSD/2.8/pmax/</a></b>
1253
1254 </pre>
1255
1256 <li>Execute the following commands:
1257 <p><table border="0"><tr><td><tt>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</tt></td><td><pre>
1258 <b>mv ftp.se.openbsd.org/pub/OpenBSD/2.8/pmax/simpleroot28.fs.gz .
1259 gunzip simpleroot28.fs.gz
1260 chmod +w simpleroot28.fs</b> &lt;--- make sure
1261 </pre></td></tr></table>
1262 <li>You now need to make an ISO image of the entire directory you downloaded.
1263 (I recommend using <tt>mkisofs</tt> for that purpose. If you don't
1264 already have <tt>mkisofs</tt> installed on your system, you need
1265 to install it in order to do this.)<pre>
1266 <b>mkisofs -o openbsd_pmax_2.8.iso ftp.se.openbsd.org/pub/OpenBSD/2.8/pmax</b>
1267 <b>rm -rf ftp.se.openbsd.org</b> <i>(this directory is not needed anymore)</i>
1268
1269 </pre>
1270 <li>Start the emulator with all three (!) disk images:<pre>
1271 <b>gxemul -e 3max -d obsd_pmax.img -d b:simpleroot28.fs -j bsd -d c:openbsd_pmax_2.8.iso</b>
1272
1273 </pre>
1274 (If you add <tt>-X</tt>, you will run with the graphical
1275 framebuffer. This is <i>REALLY</i> slow because the console has to
1276 scroll a lot during the install. I don't recommend it.)
1277 <p>
1278 <li>Go on with the installation as you would do if you were installing on a real machine.
1279 If you are not used to the OpenBSD installer, then this will most likely
1280 be a very uncomfortable experience. Some important things to keep in mind are:
1281 <ul>
1282 <li>rz0 is the rootdisk you wish to install onto.
1283 <li>rz1 is the simpleroot image.
1284 <li>rz2 is the CDROM containing the "install sets".
1285 <li>When asked for the "<b>root device?</b>", enter <b>rz1</b>.
1286 <li>At "<b>Enter pathname of shell or RETURN for sh:</b>", press enter.
1287 <li>At the # prompt, do the following:<pre>
1288 <b>fsck /dev/rz1a</b> (and mark the filesystem as clean)
1289 <b>mount /dev/rz1a /</b>
1290 <b>mkdir /kern</b>
1291 <b>mkdir /mnt2</b>
1292 <b>mount -t kernfs kern kern</b>
1293 <b>./install</b>
1294
1295 </pre>
1296 and proceed with the install. Good luck. :-)
1297 <li>Answer "<b>y</b>" when asked if you wish to configure the network.
1298 (See the section about installing NetBSD/pmax for suitable
1299 network settings.)
1300 <li>Install from "<b>c</b>" (cdrom), choose "<b>rz2</b>" as the cdrom device, and "<b>/</b>" as
1301 the directory containing the install sets.
1302 </ul>
1303 <p>
1304 <li>For some unknown reason, the install script does not set the root
1305 password! The first time you boot up OpenBSD after the install, you
1306 need to go into single user mode and run <b>passwd root</b> to set
1307 the root password, or you will not be able to log in at all!<pre>
1308 <b>gxemul -e 3max -d obsd_pmax.img -d 2c:openbsd_pmax_2.8.iso -j bsd -o '-s'</b>
1309 </pre>
1310 While you are at it, you might want to extract the X11 install sets
1311 as well, as the installer seems to ignore them too. (Perhaps due to a bug
1312 in the installer, perhaps because of the way I used mkisofs.)
1313 <p>
1314 Execute the following commands in the emulator:
1315 <p><table border="0"><tr><td><tt>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</tt></td><td><pre>
1316 <b>fsck /dev/rz0a
1317 mount /
1318 passwd root
1319
1320 cd /; mount -t cd9660 /dev/rz2c /mnt; sh
1321 for a in /mnt/[xX]*; do tar zxvf $a; done
1322 ln -s /usr/X11R6/bin/Xcfbpmax /usr/X11R6/bin/X
1323 ln -s /dev/fb0 /dev/mouse
1324 echo /usr/X11R6/lib &gt;&gt; /etc/ld.so.conf
1325 ldconfig
1326
1327 sync
1328 halt</b>
1329 </pre></td></tr></table>
1330 </ol>
1331
1332 <p>
1333 NOTE: It is also possible to install via ftp instead of using a CDROM image.
1334 This is not much less awkward, you still need the simpleroot filesystem
1335 image, and you still have to manually add the X11 install sets and set the
1336 root password, and so on.
1337
1338 <p>
1339 Once you have completed the installation procedure, the following command
1340 will let you boot from the new rootdisk image:
1341 <pre>
1342 <b>gxemul -e 3max -X -o '-aN' -d obsd_pmax.img -j bsd</b>
1343 </pre>
1344
1345 <p>
1346 (Normally, you would be asked about which root device to use (<tt>rz0</tt>),
1347 but using <b><tt>-o '-aN'</tt></b> supresses that.)
1348
1349 <p>
1350 When asked for which terminal type to use, when logging in as root,
1351 enter <b><tt>rcons</tt></b> if you are using the graphical framebuffer,
1352 <b><tt>vt100</tt></b> for text-mode.
1353 <br>Use <b><tt>startx</tt></b> to start X windows.

1365 <h3>OpenBSD/cats:</h3>
1366
1367 It is possible to install and run
1368 <a href="http://www.openbsd.org/cats.html">OpenBSD/cats</a>
1369 in GXemul. Unfortunately, "The OpenBSD/cats port has been discontinued
1370 after the 4.0 release." according to

1376
1377 <p>To install OpenBSD/cats onto an emulated harddisk image,
1378 follow these instructions:
1379
1380 <p>
1381 <ol>
1382 <li>Create an empty harddisk image, which will be the root disk
1383 that OpenBSD installs itself onto:<pre>
1384 <b>dd if=/dev/zero of=obsd_cats.img bs=1024 count=1 seek=1900000</b>
1385
1386 </pre>
1387 <li>Download the entire cats directory from the ftp server:<pre>
1388 <b>wget -np -l 0 -r <a href="ftp://ftp.se.openbsd.org/pub/OpenBSD/4.0/cats/">ftp://ftp.se.openbsd.org/pub/OpenBSD/4.0/cats/</a></b>

1390 <b>cp ftp.se.openbsd.org/pub/OpenBSD/4.0/cats/bsd.rd .</b>
1391
1392 </pre>
1393 (Replace ftp.se.openbsd.org with a server closer to you, for
1394 increased download speed.)
1395 <p>
1396 <li>You now need to make an ISO image of the entire directory you downloaded.
1397 (I recommend using <tt>mkisofs</tt> for that purpose. If you don't
1398 already have <tt>mkisofs</tt> installed on your system, you need
1399 to install it in order to do this.)<pre>
1400 <b>mkisofs -allow-lowercase -o openbsd_cats_4.0.iso ftp.se.openbsd.org/pub/OpenBSD/</b>
1401 <b>rm -rf ftp.se.openbsd.org</b> <i>(this directory is not needed anymore)</i>
1402
1403 </pre>
1404 <li>Start the emulator using this command line:<pre>
1405 <b>gxemul -XEcats -d obsd_cats.img -d openbsd_cats_4.0.iso bsd.rd</b>
1406
1407 </pre>
1408 and proceed like you would do if you were installing OpenBSD
1409 on a real CATS. (Install onto <tt>wd0</tt>, don't configure the
1410 network, install from CD.)
1411 </ol>
1412
1413 <p>(Although it <i>is</i> possible to configure the network, IPv4 address
1414 10.0.0.1, netmask 255.0.0.0, gateway/default route 10.0.0.254, and
1415 nameserver 10.0.0.254, the userland NAT-like networking layer is not
1416 stable enough yet to support a full install via ftp.)
1417
1418 <p><b>NOTE:</b> Make sure that you <tt>sync</tt> and <tt>reboot</tt>
1419 correctly once the installation is finished, or the <tt>/dev</tt> nodes
1420 may not have been written correctly to disk.
1421
1422 <p>Once the install has finished, the following command should let you
1423 boot from the harddisk image:

1438 <h3>Ultrix/RISC:</h3>
1439
1440 Ultrix 4.x can run in GXemul on an emulated DECstation 5000/200.
1441 (Ultrix was the native OS for these machines, but
1442 <a href="#netbsdpmaxinstall">NetBSD/pmax</a> is also usable.)
1443
1444 <p>
1445 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

1449
1450 <p>
1451 The following instructions should let you install Ultrix onto a disk image:
1452
1453 <ol>
1454 <li>Create an empty harddisk image, which will be the root disk
1455 that Ultrix installs itself onto:<pre>
1456 <b>dd if=/dev/zero of=rootdisk.img bs=1024 count=1 seek=800000</b>
1457
1458 </pre>
1459 <li>Place your Ultrix installation media in your CDROM drive.
1460 (On FreeBSD and similar systems, it is called <tt>/dev/cd0c</tt>.
1461 Replace that with the name of your CDROM drive, or the name of a
1462 .iso image file.) Then, start the emulator like this:<pre>
1463 <b>gxemul -X -e 3max -d rootdisk.img -d bc:/dev/cd0c -j vmunix</b>
1464
1465 </pre>
1466 <li>Once the first stage of the installation is done (restoring the root
1467 filesystem), you need to restart the emulator, booting from the
1468 new rootdisk, to continue the installation process.
1469 This is done by removing the bootflag ('<tt>b</tt>') from the second
1470 diskimage argument:<pre>
1471 <b>gxemul -X -e 3max -d rootdisk.img -d c:/dev/cd0c -j vmunix</b>
1472
1473 </pre>
1474 </ol>
1475
1476 <p>
1477 When the installation is completed, the following command should start
1478 Ultrix from the harddisk image:<pre>
1479 <b>gxemul -X -e 3max -j vmunix -d rootdisk.img</b>
1480 </pre>
1481
1482 <p>If you have a very fast host machine, you might experience a weird
1483 timer related bug, which makes it impossible to logon to the system. It is
1484 triggered when the emulation goes faster than any real DECstation machine
1485 was capable of running. A temporary workaround is to add
1486 <b><tt>-I33000000</tt></b> to fix the emulated clock speed to 33 million
1487 instructions per emulated second.
1488
1489 <p>If the workaround above doesn't work, you can also start up other
1490 processes on the host, apart from the emulator, so that the emulator runs
1491 more slowly. This is an ugly workaround, but seems to work. Once you have
1492 logged in into Ultrix, you can kill the extra processes.
1493
1494 <p>You can experiment with adding <b><tt>-Z2</tt></b> (for emulating a
1495 dual-headed workstation) or even <b><tt>-Z3</tt></b> (tripple-headed), and
1496 also the <b><tt>-Y2</tt></b> option for scaling down the framebuffer
1497 windows by a factor 2x2.
1498 There is also a <b><tt>-z</tt></b> option for supplying names of X11
1499 displays to use. The following example starts Ultrix on an emulated
1500 tripple-headed workstation, on three different displays (<tt>remote1:0.0</tt>,
1501 <tt>localhost:0.0</tt>, and <tt>remote2:0.0</tt>), using no scaledown:<pre>
1502 <b>gxemul -N -e 3max -jgenvmunix -d rootdisk.img \
1503 -XZ3 -z remote1:0.0 -z localhost:0.0 -z remote2:0.0</b>
1504 </pre>
1505
1506 <p>The photo below shows a single Ultrix session running tripple-headed in
1507 GXemul on an Alpha 21164PC, with displays on a Sun Ultra1 (to the left),
1508 on the Alpha itself (in the middle), and on an HP700/RX X-terminal (8-bit
1509 color depth, running off the Alpha) to the right.
1510
1511 <p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
1512 <a href="20041209-ultrix-tripplehead.jpg"><img src="20041209-ultrix-tripplehead_small.jpg"></a>
1513
1514 <p>The X11 displays may differ in bit depth and endianness. Unfortunately,
1515 there is no way yet to set the scaledown factor on a per-window basis, so
1516 the scaledown factor affects all windows.
1517
1518 <p>(If you didn't use <tt><b>-Z<i>n</i></b></tt> during the installation, and
1519 compiled your own <tt>/vmunix</tt>, then it will not contain support for
1520 multiple graphics cards. To overcome this problem, use the generic kernel,
1521 <tt><b>-j genvmunix</b></tt>, whenever you are running the emulator with a
1522 different setup than the one you used when Ultrix was installed.)
1523
1524 <p>A note for the historically interested: OSF/1 for MIPS was quite similar
1525 to Ultrix, so that is possible to run as well. If you are unsuccessful
1526 in installing Ultrix or OSF/1 directly in the emulator, you can always
1527 install it on your real machine onto a real SCSI disk, and then copy the
1528 contents of that SCSI disk into a file (using <b><tt>dd(1)</tt></b>), and use
1529 that file as a disk image file in the emulator.

1602 <h3>Debian GNU/Linux for DECstation:</h3>
1603
1604 It is possible to run Debian GNU/Linux for DECstation in the emulator,
1605 on an emulated 5000/200 ("3max"). However, just choosing any
1606 Linux/DECstation kernel at random for the installation will not work.
1607
1608 <p><ul>
1609 <li>Linux 2.4/DECstation DZ serial console output doesn't work too well in
1610 GXemul. Linux oopses randomly, which may be due to bugs in GXemul,
1611 but may also be due to bugs in the serial controller code in Linux.
1612 (The speed at which serial interrupts are generated can be
1613 lowered with the <tt>-U</tt> command line option, but it only
1614 reduces the risk, it doesn't take away the oopses completely.)
1615 <li>The Linux 2.6/DECstation DZ serial console driver doesn't work at
1616 all in the emulator, and I'm not really sure it would work on a
1617 real 5000/200 either. Hopefully this will be fixed in Linux in
1618 the future.
1619 <li>To get around the serial console problem, the obvious solution is to
1620 use a graphical framebuffer instead. Old Debian install kernels
1621 supported the graphical framebuffer on the 3max, but not the
1622 keyboard. (This has been fixed now, it seems.)
1623 <li>For quite some time, the MIPS linux cvs tree has had support for the
1624 framebuffer and keyboard, but it did not include Debian's
1625 patches for networking, which made it unusable for network
1626 installs. (Possibly fixed now.)
1627 <li>The kernel has to be for 5000/200. This rules out using
1628 the default kernel on netinst ISO images provided by Debian.
1629 These ISO images boot directly into a kernel which is meant
1630 for a different DECstation model.
1631 <li>The kernel has to have an initrd which more or less matches the
1632 version of Debian that will be installed.
1633 </ul>
1634
1635 <p>Luckily, a precompiled install kernel has been made available by David
1636 Muse, for Debian for R3000 DECstations, which has support for framebuffer,
1637 keyboard, and networking, which works pretty well. Thanks David. :-)
1638
1639 <p>The following steps should let you install Debian GNU/Linux for
1640 DECstation onto a harddisk image in the emulator:
1641
1642 <p>
1643 <ol>
1644 <li>Create an empty harddisk image, which will be the root disk
1645 that Debian installs itself onto:<pre>
1646 <b>dd if=/dev/zero of=debian_pmax.img bs=1024 count=1 seek=6000000</b>
1647
1648 </pre>

1747
1748 <p>
1749 The following steps should let you run Redhat Linux for DECstation in GXemul:
1750
1751 <p>
1752 <ol>
1753 <li>Download a kernel. David Muse' Debian-install kernel works fine:<pre>
1754 <a href="http://www.firstworks.com/mips-linux-2.4.31/vmlinux-2.4.31">http://www.firstworks.com/mips-linux-2.4.31/vmlinux-2.4.31</a>
1755
1756 </pre>
1757 <li>Download a root filesystem tree:<pre>
1758 <a href="ftp://ftp.linux-mips.org/pub/linux/mips/mipsel-linux/root/mipsel-root-20011216.tgz">ftp://ftp.linux-mips.org/pub/linux/mips/mipsel-linux/root/mipsel-root-20011216.tgz</a>
1759 19486676 bytes, md5 = 5bcb725c90209479cd7ead8ad0c4a414
1760
1761 </pre>
1762 <li>Create a disk image which will contain the Redhat filesystem:<pre>
1763 <b>dd if=/dev/zero of=redhat_mips.img bs=1024 count=1 seek=2000000</b>
1764
1765 </pre>
1766 <li>This is the tricky part: on redhat_mips.img, you need to create an MS-DOS
1767 (!) partition table, and then an ext2 partition. This is what Linux
1768 will then see as /dev/sda1.
1769 <p>I recommend you run fdisk and mke2fs and untar the archive from within
1770 Debian/DECstation or <a href="#debiancats">Debian/CATS</a> running
1771 inside the emulator. (Alternatively, if you are on a Linux host,
1772 you could use a loopback mount, or similar. This might require
1773 root access. See e.g.
1774 <a href="http://www.mega-tokyo.com/osfaq2/index.php/Disk%20Images%20Under%20Linux">http://www.mega-tokyo.com/osfaq2/index.php/Disk%20Images%20Under%20Linux</a>.)
1775 <p>
1776 In order to actually boot the system you need to modify /etc/fstab.
1777 Change<pre>
1778 /dev/root / nfs defaults 1 1
1779 #/dev/sdc1 / ext2 defaults 1 1
1780 none /proc proc defaults 0 0
1781 none /dev/pts devpts mode=0622 0 0
1782
1783 </pre>to<pre>
1784 #/dev/root / nfs defaults 1 1
1785 /dev/sda1 / ext2 defaults 1 1
1786 none /proc proc defaults 0 0
1787 none /dev/pts devpts mode=0622 0 0
1788
1789 </pre>(Note sda1 instead of sdc1.)
1790 </ol>
1791
1792 <p>To boot Redhat linux from the disk image, use the following command line:<pre>
1793 <b>gxemul -X -e3max -o "root=/dev/sda1 ro" -d redhat_mips.img vmlinux-2.4.31</b>
1794
1795 </pre>
1796 If you need to boot into single user mode, change options to
1797 <tt><b>-o "root=/dev/sda1 rw init=/bin/sh"</b></tt>.

1836

1843
1844 </pre>
1845 <li>Extract the Mach kernel:<pre>
1846 <b>tar xfvz pmax.tar.Z pmax_mach/special/mach.boot.MK83.STD+ANY</b>
1847
1848 </pre>
1849 <li>Create an empty disk image:<pre>
1850 <b>dd if=/dev/zero of=disk.img bs=1 count=512 seek=400000000</b>
1851
1852 </pre>
1853 <li>Load the contents of pmax.tar.Z onto the disk image. This is
1854 complicated, and should be described in more detail some time.
1855 For now, use your imagination. (For example using OpenBSD/pmax:
1856 <i>disklabel -E rz1; newfs -O /dev/rz1a;
1857 mount /dev/rz1a /mnt; cd /mnt; download pmax.tar.Z using ftp;
1858 tar xzvf pmax.tar.Z; mv pmax_mach/* .; rmdir pmax_mach;
1859 mkdir mach_servers;
1860 cd mach_servers;
1861 cp ../etc/mach_init .;
1862 cp ../tests/test_service startup;
1863 dd if=/dev/zero of=paging_file bs=65536 count=400;
1864 cd /; sync; umount /mnt</i>)
1865 <p>
1866 <li>Start the emulator with the following command:<pre>
1867 <b>gxemul -c 'put w 0x800990e0, 0' -c 'put w 0x80099144, 0' \
1868 -c 'put w 0x8004aae8, 0' -e 3max -X -d disk.img \
1869 pmax_mach/special/mach.boot.MK83.STD+ANY</b>
1870
1871 </pre>
1872 </ol>
1873
1874 <p>Earlier versions of GXemul had a configure option to enable better
1875 R3000 cache emulation, but since Mach was more or less the only thing that
1876 used it, I removed it. Today's version of GXemul can thus not boot
1877 mach.boot.MK83.STD+ANY straight off, it has to be patched to skip the
1878 cache detection.
1879
1880 <p>The -c commands above patch the kernel to get past the cache detection.
1881 Thanks to Artur Bujdoso for these values.

1905 <p>GXemul does not yet emulate the AHC PCI SCSI controller in the O2. (I have
1906 mailed Adaptec several times, asking for documentation, but never received
1907 any reply.) OpenBSD/sgi can still run in the emulator, as long as it doesn't

1912
1913 <p>It might also be possible to netboot. Another emulated machine must

2067 <h3>OpenBSD/arc:</h3>
2068
2069 It is (almost) possible to install and run OpenBSD/arc on an emulated Acer
2070 PICA-61 in the emulator.
2071
2072 <p><font color="#e00000">Earlier, I had this guest OS listed as
2073 officially working in the emulator, but for several reasons, it has
2074 been moved down here to the "informative-but-not-really-working"
2075 section.</font>
2076
2077 <p>
2078 <ul>
2079 <li>The last OpenBSD/arc release was 2.3. This means that it is very
2080 old, it would not give a fair picture of what OpenBSD is (if you
2081 are just looking to find out what it is like), and it is not
2082 worth experimenting with it. See
2083 <a href="http://www.openbsd.org/arc.html">http://www.openbsd.org/arc.html</a>
2084 for more information.
2085 <li>OpenBSD/arc was (if I understood things correctly) never really
2086 stable, even on real hardare. Problems with too small an interrupt
2087 stack. Bugs are triggered in the emulator that have to do with
2088 issues such as this.
2089 </ul>

2094
2095 <p>
2096 <font color="#e00000">Currently, I don't test for every release whether
2097 or not OpenBSD/arc can be installed. Releases prior to 0.3.7
2098 (but probably <i>not</i> 0.3.7) should work. Anyway, here are the
2099 old installation instructions:</font>
2100
2101 <p>To install OpenBSD/arc onto an emulated harddisk image, follow these
2102 instructions:
2103
2104 <p>
2105 <ol>
2106 <li>Create an empty harddisk image, which will be the root disk
2107 that OpenBSD installs itself onto:<pre>
2108 <b>dd if=/dev/zero of=obsd_arc.img bs=1024 count=1 seek=700000</b>
2109
2110 </pre>
2111 <li>Download the entire arc directory from the ftp server: (approx. 75 MB)<pre>
2112 <b>wget -np -l 0 -r <a href="ftp://ftp.se.openbsd.org/pub/OpenBSD/2.3/arc/">ftp://ftp.se.openbsd.org/pub/OpenBSD/2.3/arc/</a></b>
2113
2114 </pre>
2115
2116 <li>You now need to make an ISO image of the entire directory you downloaded.
2117 (I recommend using <tt>mkisofs</tt> for that purpose. If you don't
2118 already have <tt>mkisofs</tt> installed on your system, you need
2119 to install it in order to do this.)<pre>
2120 <b>mkisofs -o openbsd_arc_2.3.iso ftp.se.openbsd.org/pub/OpenBSD/</b>
2121
2122 </pre>
2123 <li>Start the emulator using this command line:<pre>
2124 <b>gxemul -e pica -X -d obsd_arc.img -d b:openbsd_arc_2.3.iso -j 2.3/arc/bsd.rd</b>
2125
2126 </pre>
2127 and proceed like you would do if you were installing OpenBSD
2128 on a real Acer PICA-61. (Answer 'no' when asked if you want to
2129 configure networking, and then install from CD-ROM.)
2130 </ol>
2131
2132 <p>
2133 Once the install has finished, the following command should let you
2134 boot from the harddisk image:
2135 <p>
2136 <pre>
2137 <b>gxemul -X -e pica -d obsd_arc.img ftp.se.openbsd.org/pub/OpenBSD/2.3/arc/bsd</b>
2138
2139 </pre>
2140
2141 The system is very sensitive to (I think) kernel stack overflow, so it
2142 crashes easily. If I remember correctly from mailing lists, this also
2143 happened on real hardware.

2157 <h3>Debian GNU/Linux for CATS:</h3>
2158
2159 Debian GNU/Linux for CATS (ARM) could <i>theoretically</i> run in GXemul,
2160 however:
2161
2162 <ul>
2163 <li>The DEC 21143 NIC is not emulated well enough for Linux to accept it.
2164 <li>Development of Debian for CATS seems to have died? The latest
2165 install kernel is quite old.
2166 </ul>
2167
2168 <p><font color="#ff0000">IT DOES <b>NOT</b> WORK YET!</font>
2169
2170 <p>The following installation instructions would theoretically work:
2171
2172 <p>
2173 <ol>
2174 <li>Create an empty harddisk image, which will be the root disk
2175 that Debian installs itself onto:<pre>
2176 <b>dd if=/dev/zero of=debian_cats.img bs=1024 count=1 seek=3300000</b>
2177
2178 </pre>
2179 <li>Download the tftpboot install kernel:<pre>
2180 <a href="http://ftp.debian.org/debian/dists/oldstable/main/disks-arm/current/cats/tftpboot.img">http://ftp.debian.org/debian/dists/oldstable/main/disks-arm/current/cats/tftpboot.img</a>
2181
2182 </pre>
2183 <li>Start the installation using the following command line:<pre>
2184 <b>gxemul -XEcats -d debian_cats.img tftpboot.img</b>
2185
2186 </pre>
2187 </ol>
2188
2189 <p>It doesn't work, though, because the NIC isn't working well enough.
2190
2191 <p>The only use of Debian/CATS in the emulator right now is as a way to
2192 manipulate Linux disk images, if you are on a non-Linux host. By choosing
2193 "Execute a shell" in the installer's menu, you can have access to tools such as
2194 fdisk and mke2fs, which are useful for creating Linux paritions on disk images.

2209 to experiment with Linux/Malta as well.
2210
2211 <p>The general idea behind Linux/Malta seems to be that the end user
2212 always compiles his/her own kernel, applies patches, downloads
2213 userland separately, etc. For that reason, Linux/Malta support in the

2299 <h3>Windows NT/MIPS:</h3>

2301 Old versions of Windows NT could run on MIPS hardware, e.g.
2302 the PICA 61. It is theoretically possible that the emulation provided by
2303 GXemul some day could be stable/complete enough to emulate
2304 such hardware well enough to fool Windows NT into thinking
2305 that it is running on a real machine.
2306 <font color="#ff0000">IT DOES <b>NOT</b> WORK YET!</font>
2307
2308 <p>Installation steps similar to these would be required to install
2309 Windows NT onto a disk image:
2310
2311 <ol>
2312 <li>Put a "Windows NT 4.0 for MIPS" CDROM (or similar) into
2313 your CDROM drive. (On FreeBSD systems, it is
2314 usually called <tt>/dev/cd0c</tt> or similar. Change
2315 that to whatever the CDROM is called on your system,
2316 or the name of a raw .iso image. I have tried this
2317 with the Swedish version, but it might work with
2318 other versions too.)
2319 <p>
2320 <li>Create an empty harddisk image, which will be the disk image
2321 that you will install Windows NT onto:<pre>
2322 $ <b><tt>dd if=/dev/zero of=winnt_test.img bs=1024 count=1 seek=999000</tt></b>
2323
2324 </pre>
2325 <li>Run the ARC installer, to partition the disk image:<pre>
2326 $ <b><tt>gxemul -X -e pica -d winnt_test.img -d bc6:/dev/cd0c -j MIPS\\ARCINST</tt></b>
2327 </pre>
2328 Note that <tt>ARCINST</tt> <i>almost</i> works, but not quite.
2329 <p>
2330 <li>Run the SETUP program:<pre>
2331 $ <b><tt>gxemul -X -e pica -d winnt_test.img -d bc6:/dev/cd0c -j MIPS\\SETUPLDR</tt></b>
2332 </pre>
2333 </ol>
2334
2335 <p><tt>SETUPLDR</tt> manages to load some drivers from the cdrom,
2336 but then it crashes because of incomplete emulation of some hardware devices.

2519 that OpenBSD installs itself onto:<pre>
2520 <b>dd if=/dev/zero of=obsd_landisk.img bs=1024 count=1 seek=900000</b>
2521
2522 </pre>
2523 <li>Download the entire landisk directory from the ftp server:<pre>
2524 <b>wget -np -l 0 -r <a href="ftp://ftp.se.openbsd.org/pub/OpenBSD/snapshots/landisk/">ftp://ftp.se.openbsd.org/pub/OpenBSD/snapshots/landisk/</a></b>
2525 <b>cp ftp.se.openbsd.org/pub/OpenBSD/snapshots/landisk/bsd .</b>
2526 <b>cp ftp.se.openbsd.org/pub/OpenBSD/snapshots/landisk/bsd.rd .</b>
2527
2528 </pre>
2529 (Replace ftp.se.openbsd.org with a server closer to you, for
2530 increased download speed.)
2531 <p>
2532 <li>You now need to make an ISO image of the entire directory you downloaded.
2533 (I recommend using <tt>mkisofs</tt> for that purpose. If you don't
2534 already have <tt>mkisofs</tt> installed on your system, you need
2535 to install it in order to do this.)<pre>
2536 <b>mkisofs -allow-lowercase -o openbsd_landisk_snapshot.iso ftp.se.openbsd.org/pub/OpenBSD/</b>
2537 <b>rm -rf ftp.se.openbsd.org</b> <i>(this directory is not needed anymore)</i>
2538
2539 </pre>
2540 <li>Start the emulator using this command line:<pre>
2541 <b>gxemul -x -Elandisk -d obsd_landisk.img -d d:openbsd_landisk_snapshot.iso bsd.rd</b>
2542
2543 </pre>
2544 and proceed like you would do if you were installing OpenBSD
2545 on a real landisk. The following hints are useful to get you
2546 through the installation:
2547 <ul>
2548 <li>Terminal type = <b>xterm</b>
2549 <li>root disk = <b>wd0</b> (the disk to install onto)
2550 <li>Use the entire disk for OpenBSD = <b>yes</b>
2551 <li>Create one big root partition (a) and a small swap partition (b). c is the entire disk.
2552 <li>Do <b>not</b> configure the network.
2553 <li>Location of sets = <b>disk</b>
2554 <li>Is the disk partition already mounted = <b>no</b>
2555 <li>Disk containing the install media = <b>wd1</b>
2556 <li>Pathname to the sets = <b>snapshot/landisk</b>
2557 </ul>
2558 </ol>
2559
2560 <p>Once the install has finished, the following command should let you
2561 boot from the disk image:
2562
2563 <p><pre>
2564 <b>gxemul -x -E landisk -d obsd_landisk.img bsd</b>
2565
2566 </pre>
2567
2568
2569
2570
2571
2572
2573
2574 </p>
2575
2576 </body>
2577 </html>
