20060626	Continuing on SPARC emulation (beginning on the 'save'
		instruction, register windows, etc).
20060629	Planning statistics gathering (new -s command line option),
		and renaming speed_tricks to allow_instruction_combinations.
20060630	Some minor manual page updates.
		Various cleanups.
		Implementing the -s command line option.
20060701	FINALLY found the bug which prevented Linux and Ultrix from
		running without the ugly hack in the R2000/R3000 cache isol
		code; it was the phystranslation hint array which was buggy.
		Removing the phystranslation hint code completely, for now.
20060702	Minor dyntrans cleanups; invalidation of physpages now only
		invalidate those parts of a page that have actually been
		translated. (32 parts per page.)
		Some MIPS non-R3000 speed fixes.
		Experimenting with MIPS instruction combination for some
		addiu+bne+sw loops, and sw+sw+sw.
		Adding support (again) for larger-than-4KB pages in MIPS tlbw*.
		Continuing on SPARC emulation: adding load/store instructions.
20060704	Fixing a virtual vs physical page shift bug in the new tlbw*
		implementation. Problem noticed by Jakub Jermar. (Many thanks.)
		Moving rfe and eret to cpu_mips_instr.c, since that is the
		only place that uses them nowadays.
20060705	Removing the BSD license from the "testmachine" include files,
		placing them in the public domain instead; this enables the
		testmachine stuff to be used from projects which are
		incompatible with the BSD license for some reason.
20060707	Adding instruction combinations for the R2000/R3000 L1
		I-cache invalidation code used by NetBSD/pmax 3.0, lui+addiu,
		various branches followed by addiu or nop, and jr ra followed
		by addiu. The time it takes to perform a full NetBSD/pmax R3000
		install on the laptop has dropped from 573 seconds to 539. :-)
20060708	Adding a framebuffer controller device (dev_fbctrl), which so
		far can be used to change the fb resolution during runtime, but
		in the future will also be useful for accelerated block fill/
		copy, and possibly also simplified character output.
		Adding an instruction combination for NetBSD/pmax' strlen.
20060709	Minor fixes: reading raw files in src/file.c wasn't memblock
		aligned, removing buggy multi_sw MIPS instruction combination,
		etc.
20060711	Adding a machine_qemu.c, which contains a "qemu_mips" machine.
		(It mimics QEMU's MIPS machine mode, so that a test kernel
		made for QEMU_MIPS also can run in GXemul... at least to some
		extent.)  Adding a short section about how to run this mode to
		doc/guestoses.html.
20060714	Misc. minor code cleanups.
20060715	Applying a patch which adds getchar() to promemul/yamon.c
		(from Oleksandr Tymoshenko).
		Adding yamon.h from NetBSD, and rewriting yamon.c to use it
		(instead of ugly hardcoded numbers) + some cleanup.
20060716	Found and fixed the bug which broke single-stepping of 64-bit
		programs between 0.4.0 and 0.4.0.1 (caused by too quick
		refactoring and no testing). Hopefully this fix will not
		break too many other things.
20060718	Continuing on the 8253 PIT; it now works with Linux/QEMU_MIPS.
		Re-adding the sw+sw+sw instr comb (the problem was that I had
		ignored endian issues); however, it doesn't seem to give any
		big performance gain.
20060720	Adding a dummy Transputer mode (T414, T800 etc) skeleton (only
		the 'j' and 'ldc' instructions are implemented so far). :-}
20060721	Adding gtreg.h from NetBSD, updating dev_gt.c to use it, plus
		misc. other updates to get Linux 2.6 for evbmips/malta working
		(thanks to Alec Voropay for the details).
		FINALLY found and fixed the bug which made tlbw* for non-R3000
		buggy; it was a reference count problem in the dyntrans core.
20060722	Testing stuff; things seem stable enough for a new release.

75     <h3>General notes on running "guest OSes":</h3>
76    
77     The emulator works well enough to run complete operating systems. These
78 dpavlin 24 are often refered to as <i>guest</i> operating systems, in contrast to the
79     <i>host</i> operating system which the emulator is running under.
80 dpavlin 2
81 dpavlin 24 <p>Although it is possible to let a guest OS access real hardware, such as
82     harddisks, it is much more flexible and attractive to simulate harddisks
83     using files residing in the host's filesystem. On Unix-like systems, files
84     may contain holes, which makes this really simple. To the guest operating
85 dpavlin 2 system, the harddisk image looks and acts like a real disk.
86    
87 dpavlin 24 <p>The version numbers of the various operating systems were the latest
88     versions that worked satisfactory with GXemul at the time this page was
89     updated; if new versions have been released since then, they might work as
90     well.
91 dpavlin 2
92 dpavlin 24 <p>In addition to the "working" guest operating systems listed above,
93     you might find the following information interesting: (Some of these might
94     not be relevant for this specific release of GXemul.)
95 dpavlin 2

98     <li><a href="#openbsdsgiinstall">OpenBSD/sgi</a>
99     <li><a href="#openbsdarcinstall">OpenBSD/arc 2.3</a>
100     <li><a href="#debiancats">Debian GNU/Linux for CATS</a>
101 dpavlin 28 <li><a href="#linux_qemu_mips">Linux/QEMU_MIPS</a>
102     <li><a href="#windows_nt_mips">Windows NT/MIPS</a>
103 dpavlin 24 <li><a href="#netbsdnetwinderinstall">NetBSD/netwinder 2.1</a>
104     <li><a href="#netbsdmacppcinstall">NetBSD/macppc 3.0</a>
105     </ul>
106 dpavlin 2
107 dpavlin 24 <p>Some operating systems are listed with a version number <i>less</i>
108     than what was available at the time of this GXemul release (e.g.
109     NetBSD/prep). The reasons for this is because of incompleteness in
110     GXemul's machine, device, and/or processor implementations.
111 dpavlin 2

120 dpavlin 10 <h3>NetBSD/pmax:</h3>
121 dpavlin 2
122 dpavlin 24 <p><a href="http://www.netbsd.org/Ports/pmax/">NetBSD/pmax</a> was the
123 dpavlin 28 first guest OS that could be
124     <a href="http://mail-index.netbsd.org/port-pmax/2004/04/18/0000.html">installed</a>
125     onto a disk image in GXemul. The device emulation of the DECstation
126     5000/200 is reasonably complete; it should be enough to emulate a
127     networked X-windows-capable workstation.
128 dpavlin 24
129     <p>NetBSD/pmax 1.6.2 works perfectly with X out-of-the-box. Unfortunately,
130     newer NetBSD releases have changed slightly, and nowadays X does not
131     work straight away. (It seems that this has to do with NetBSD switching
132     console system to "WSCONS" somewhere between 1.6.2 and 2.0. I haven't had
133     time to figure out how to make it work; at worst it might require a kernel
134     recompilation.) What this means is that if you want to use emulated X11,
135     then you need to run NetBSD 1.6.2. If you feel that you only need
136     serial-console emulation, then choose the latest NetBSD version available.
137    
138     <p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
139 dpavlin 6 <a href="20050317-example.png"><img src="20050317-example_small.png"></a>
140 dpavlin 4
141 dpavlin 24 <p>To install NetBSD/pmax onto a harddisk image in the emulator,
142     follow these instructions:
143 dpavlin 2
144 dpavlin 10 <p><ol start="1">
145 dpavlin 2 <li>Create an empty harddisk image, which will be the root disk
146     that NetBSD installs itself onto:<pre>
147 dpavlin 24 <b>dd if=/dev/zero of=nbsd_pmax.img bs=1024 count=1 seek=1900000</b>
148 dpavlin 2
149     </pre>
150     </ol>
151 dpavlin 4
152 dpavlin 2 <p>
153     From this point, there are two separate ways to continue the installation.
154     You can either download a CD-ROM iso image (and let the installation
155     program copy files from the CD-ROM image to the harddisk image), or you
156     can install via ftp. For an installation from a CD-ROM image, follow these
157     steps:
158     <p>
159     <ol start="2">
160    
161     <li>Download a NetBSD CD-ROM iso image:<pre>
162 dpavlin 24 <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>
163 dpavlin 2 or
164 dpavlin 22 <a href="ftp://ftp.netbsd.org/pub/NetBSD/iso/3.0/pmaxcd-3.0.iso">ftp://ftp.netbsd.org/pub/NetBSD/iso/3.0/pmaxcd-3.0.iso</a>
165 dpavlin 2
166     </pre>
167     <li>Start the emulator like this:<pre>
168 dpavlin 24 <b>gxemul -e 3max -d nbsd_pmax.img -d bc:pmaxcd-3.0.iso</b>
169 dpavlin 22 (or <b>pmaxcd.iso</b>)
170 dpavlin 2 </pre>
171 dpavlin 10 and proceed like you would do if you were installing NetBSD on a real
172 dpavlin 12 DECstation. Remember to choose <tt>vt100</tt> as your terminal
173     type, and not <tt>rcons</tt>.
174 dpavlin 2 </ol>
175     <p>
176     For an ftp install, substitute steps 2 and 3 above with these:
177     <p>
178     <ol start="2">
179    
180 dpavlin 10 <li>Download a NetBSD pmax INSTALL kernel:<pre>
181 dpavlin 24 <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>

184 dpavlin 2
185     </pre>
186     <li>Start the emulator like this:<pre>
187 dpavlin 24 <b>gxemul -e 3max -d nbsd_pmax.img -O netbsd-INSTALL.gz</b>
188 dpavlin 2 </pre>
189 dpavlin 10 and proceed like you would do if you were installing NetBSD on a real
190 dpavlin 12 DECstation. Remember to choose <tt>vt100</tt> as your terminal
191     type, and not <tt>rcons</tt>. Suitable networking parameters are as
192     follows:<pre>
193 dpavlin 2 Which device shall I use? [le0]: <b>le0</b>
194     ..
195     Your DNS domain: <b>mydomain.com</b>
196     Your host name: <b>foo</b>
197     Your IPv4 number: <b>10.0.0.1</b>
198     IPv4 Netmask [0xff000000]: <b>0xff000000</b>
199     IPv4 gateway: <b>10.0.0.254</b>
200     IPv4 name server: <b>10.0.0.254</b>
201     </pre>
202 dpavlin 10 (If using 10.0.0.254 as the nameserver fails, then try entering the
203     IP number of a real-world nameserver instead.)
204     </ol>
205 dpavlin 2
206 dpavlin 12 <p>If you want to use a graphical framebuffer during the install, you can
207     add <b><tt>-X -Y2</tt></b> to the command line, and choose <tt>rcons</tt>
208     instead of <tt>vt100</tt> when prompted with which terminal type to use.
209     (By just using <tt><b>-X</b></tt>, you will get a full-size framebuffer
210     window.)
211 dpavlin 2
212 dpavlin 12 <p>When the installation is finished, the following command should start
213 dpavlin 2 NetBSD from the harddisk image:<pre>
214 dpavlin 12 <b>gxemul -e 3max -d nbsd_pmax.img</b>
215 dpavlin 2 </pre>
216    
217 dpavlin 24 <p>If you installed NetBSD/pmax 1.6.2, then try the following to start
218     with a framebuffer:<pre>
219 dpavlin 12 <b>gxemul -X -e 3max -d nbsd_pmax.img</b>
220 dpavlin 2 </pre>
221 dpavlin 12 and log in as <tt>root</tt> and type <tt>startx</tt> to start X windows.

392 dpavlin 2
393     </pre>
394     and proceed like you would do if you were installing NetBSD on a real
395 dpavlin 12 MobilePro 770. (Install onto wd0, choose "Use entire disk" when
396 dpavlin 20 doing the MBR partitioning, and choose to install from CD-ROM.)
397 dpavlin 2 </ol>
398    
399     <p>
400     If everything worked, NetBSD should now be installed on the disk image.
401 dpavlin 12 Use the following command line to boot the emulated hpcmips machine:<pre>

406 dpavlin 12 <p>If you change your mind at this point regarding which machine type to
407     emulate, you might for example prefer a MobilePro 800, then you can change
408     that at any time. NetBSD/hpcmips is designed to be able to boot on many
409     types, without any need to change the kernel.

753     For example, when NetBSD says "<tt>nfs_boot: trying DHCP/BOOTP</tt>",
754     there will be a long pause, even on a very fast host machine. The reason

1036 dpavlin 24 <b>gxemul -e 3max -d obsd_pmax.img -d b:simpleroot28.fs -j bsd -d c:openbsd_pmax_2.8.iso</b>
1037 dpavlin 2
1038     </pre>
1039 dpavlin 12 (If you add <tt>-X</tt>, you will run with the graphical
1040 dpavlin 6 framebuffer. This is <i>REALLY</i> slow because the console has to
1041     scroll a lot during the install. I don't recommend it.)
1042 dpavlin 2 <p>
1043     <li>Go on with the installation as you would do if you were installing on a real machine.
1044     If you are not used to the OpenBSD installer, then this will most likely
1045     be a very uncomfortable experience. Some important things to keep in mind are:
1046     <ul>
1047     <li>rz0 is the rootdisk you wish to install onto.
1048     <li>rz1 is the simpleroot image.
1049     <li>rz2 is the CDROM containing the "install sets".
1050     <li>When asked for the "<b>root device?</b>", enter <b>rz1</b>.
1051     <li>At "<b>Enter pathname of shell or RETURN for sh:</b>", press enter.
1052     <li>At the # prompt, do the following:<pre>
1053 dpavlin 12 <b>fsck /dev/rz1a</b> (and mark the filesystem as clean)
1054     <b>mount /dev/rz1a /</b>
1055     <b>mount -t kernfs kern kern</b>
1056     <b>./install</b>
1057 dpavlin 2
1058     </pre>
1059     and proceed with the install. Good luck. :-)
1060     <li>Answer "<b>y</b>" when asked if you wish to configure the network.
1061     (See the section about installing NetBSD/pmax for suitable
1062     network settings.)
1063     <li>Install from "<b>c</b>" (cdrom), choose "<b>rz2</b>" as the cdrom device, and "<b>/</b>" as
1064     the directory containing the install sets.
1065     </ul>
1066     <p>
1067 dpavlin 10 <li>For some unknown reason, the install script does not set the root
1068     password! The first time you boot up OpenBSD after the install, you
1069     need to go into single user mode and run <b>passwd root</b> to set
1070     the root password, or you will not be able to log in at all!<pre>
1071 dpavlin 24 <b>gxemul -e 3max -d obsd_pmax.img -d 2c:openbsd_pmax_2.8.iso -j bsd -o '-s'</b>
1072 dpavlin 2 </pre>
1073     While you are at it, you might want to extract the X11 install sets
1074     as well, as the installer seems to ignore them too. (Perhaps due to a bug
1075     in the installer, perhaps because of the way I used mkisofs.)
1076     <p>
1077     Execute the following commands in the emulator:
1078 dpavlin 12 <p><table border="0"><tr><td><tt>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</tt></td><td><pre>
1079     <b>fsck /dev/rz0a
1080     mount /
1081     passwd root
1082 dpavlin 2
1083 dpavlin 12 cd /; mount -t cd9660 /dev/rz2c /mnt; sh
1084     for a in /mnt/[xX]*; do tar zxvf $a; done
1085     ln -s /usr/X11R6/bin/Xcfbpmax /usr/X11R6/bin/X
1086     ln -s /dev/fb0 /dev/mouse
1087     echo /usr/X11R6/lib &gt;&gt; /etc/ld.so.conf
1088     ldconfig
1089 dpavlin 2
1090 dpavlin 12 sync
1091     halt</b>
1092     </pre></td></tr></table>
1093 dpavlin 2 </ol>
1094    
1095     <p>
1096     NOTE: It is also possible to install via ftp instead of using a CDROM image.
1097     This is not much less awkward, you still need the simpleroot filesystem
1098     image, and you still have to manually add the X11 install sets and set the
1099     root password, and so on.
1100    
1101     <p>
1102     Once you have completed the installation procedure, the following command
1103     will let you boot from the new rootdisk image:
1104     <pre>
1105 dpavlin 22 <b>gxemul -e 3max -X -o '-aN' -d obsd_pmax.img -j bsd</b>
1106 dpavlin 2 </pre>
1107    
1108     <p>
1109 dpavlin 6 (Normally, you would be asked about which root device to use (<tt>rz0</tt>),
1110     but using <b><tt>-o '-aN'</tt></b> supresses that.)
1111 dpavlin 2
1112     <p>
1113     When asked for which terminal type to use, when logging in as root,
1114 dpavlin 6 enter <b><tt>rcons</tt></b> if you are using the graphical framebuffer,
1115     <b><tt>vt100</tt></b> for text-mode.
1116     <br>Use <b><tt>startx</tt></b> to start X windows.

1137     <p>To install OpenBSD/cats onto an emulated harddisk image,
1138     follow these instructions:
1139    
1140     <p>
1141     <ol>
1142     <li>Create an empty harddisk image, which will be the root disk
1143     that OpenBSD installs itself onto:<pre>
1144     <b>dd if=/dev/zero of=obsd_cats.img bs=1024 count=1 seek=1900000</b>

1154     increased download speed.)
1155     <p>
1156 dpavlin 14 <li>You now need to make an ISO image of the entire directory you downloaded.
1157     (I recommend using <tt>mkisofs</tt> for that purpose. If you don't
1158     already have <tt>mkisofs</tt> installed on your system, you need

1175     nameserver 10.0.0.254, the userland NAT-like networking layer is not
1176     stable enough yet to support a full install via ftp.)
1177    
1178 dpavlin 16 <p><b>NOTE:</b> Make sure that you <tt>sync</tt> and <tt>reboot</tt>
1179     correctly once the installation is finished, or the <tt>/dev</tt> nodes

1209 dpavlin 4
1210     <p>
1211     The following instructions should let you install Ultrix onto a disk image:
1212    
1213 dpavlin 2 <ol>
1214     <li>Create an empty harddisk image, which will be the root disk
1215     that Ultrix installs itself onto:<pre>
1216 dpavlin 12 <b>dd if=/dev/zero of=rootdisk.img bs=1024 count=1 seek=800000</b>
1217 dpavlin 2
1218     </pre>
1219 dpavlin 6 <li>Place your Ultrix installation media in your CDROM drive.
1220     (On FreeBSD and similar systems, it is called <tt>/dev/cd0c</tt>.
1221     Replace that with the name of your CDROM drive, or the name of a
1222     .iso image file.) Then, start the emulator like this:<pre>
1223 dpavlin 24 <b>gxemul -X -e 3max -d rootdisk.img -d bc:/dev/cd0c -j vmunix</b>
1224 dpavlin 2
1225     </pre>
1226     <li>Once the first stage of the installation is done (restoring the root
1227     filesystem), you need to restart the emulator, booting from the
1228     new rootdisk, to continue the installation process.
1229 dpavlin 6 This is done by removing the bootflag ('<tt>b</tt>') from the second
1230 dpavlin 2 diskimage argument:<pre>
1231 dpavlin 24 <b>gxemul -X -e 3max -d rootdisk.img -d c:/dev/cd0c -j vmunix</b>
1232 dpavlin 2
1233     </pre>
1234     </ol>
1235    
1236     <p>
1237     When the installation is completed, the following command should start
1238     Ultrix from the harddisk image:<pre>
1239 dpavlin 24 <b>gxemul -X -e 3max -j vmunix -d rootdisk.img</b>
1240 dpavlin 2 </pre>
1241    
1242 dpavlin 24 <p>If you have a very fast host machine, you might experience a weird
1243 dpavlin 10 timer related bug, which makes it impossible to logon to the system. It is
1244     triggered when the emulation goes faster than any real DECstation machine
1245     was capable of running. A temporary workaround is to add
1246     <b><tt>-I33000000</tt></b> to fix the emulated clock speed to 33 million
1247     instructions per emulated second. (When using <tt><b>-CR4400</b></tt>,
1248     <b><tt>-I16000000</tt></b> should be used instead.)
1249 dpavlin 2
1250     <p>
1251 dpavlin 6 You can experiment with adding <b><tt>-Z2</tt></b> (for emulating a
1252     dual-headed workstation) or even <b><tt>-Z3</tt></b> (tripple-headed), and
1253     also the <b><tt>-Y2</tt></b> option for scaling down the framebuffer
1254     windows by a factor 2x2.
1255     There is also a <b><tt>-z</tt></b> option for supplying names of X11
1256     displays to use. The following example starts Ultrix on an emulated
1257     tripple-headed workstation, on three different displays (<tt>remote1:0.0</tt>,
1258     <tt>localhost:0.0</tt>, and <tt>remote2:0.0</tt>), using no scaledown:<pre>
1259 dpavlin 24 <b>gxemul -N -e 3max -jgenvmunix -d rootdisk.img \
1260 dpavlin 6 -XZ3 -z remote1:0.0 -z localhost:0.0 -z remote2:0.0</b>
1261 dpavlin 2 </pre>
1262    
1263     <p>
1264 dpavlin 6 The photo below shows a single Ultrix session running tripple-headed in
1265     GXemul on an Alpha 21164PC, with displays on a Sun Ultra1 (to the left),
1266     on the Alpha itself (in the middle), and on an HP700/RX X-terminal (8-bit
1267     color depth, running off the Alpha) to the right.

1272    
1273     <p>
1274 dpavlin 2 The X11 displays may differ in bit depth and endianness. Unfortunately,
1275     there is no way yet to set the scaledown factor on a per-window basis, so
1276     the scaledown factor affects all windows.
1277    
1278     <p>
1279 dpavlin 6 (If you didn't use <tt><b>-Z<i>n</i></b></tt> during the installation, and
1280     compiled your own <tt>/vmunix</tt>, then it will not contain support for
1281     multiple graphics cards. To overcome this problem, use the generic kernel,
1282     <tt><b>-j genvmunix</b></tt>, whenever you are running the emulator with a
1283     different setup than the one you used when Ultrix was installed.)
1284 dpavlin 2
1285 dpavlin 4 <p>
1286     A note for the historically interested: OSF/1 for MIPS was quite similar
1287     to Ultrix, so that is possible to run as well. If you are unsuccessful
1288     in installing Ultrix or OSF/1 directly in the emulator, you can always
1289     install it on your real machine onto a real SCSI disk, and then copy the
1290 dpavlin 6 contents of that SCSI disk into a file (using <b><tt>dd(1)</tt></b>), and use
1291 dpavlin 4 that file as a disk image file in the emulator.

1365 dpavlin 2
1366 dpavlin 22 It is possible to run Debian GNU/Linux for DECstation in the emulator,
1367     on an emulated 5000/200 ("3max"). Although the Debian project has released
1368     install ramdisk kernels for this purpose, these do not always work:
1369     <ul>
1370 dpavlin 24 <li>Serial console output doesn't work too well in GXemul. Linux
1371     oopses randomly, which may be due to bugs in GXemul, but may
1372 dpavlin 22 also be due to bugs in the serial controller code in Linux.
1373     (The speed at which serial interrupts are generated can be
1374     lowered with the <tt>-U</tt> command line option, but it only
1375     reduces the risk, it doesn't take away the oopses completely.)
1376     <li>Old install kernels supported the graphical framebuffer on the
1377     3max, but not the keyboard.
1378     <li>For quite some time, the MIPS linux cvs tree had support for the
1379     keyboard, but it did <i>not</i> include Debian's patches for
1380     networking. (Perhaps this has been fixed now, I don't know.)

1496

1499 dpavlin 24 <li>Download a kernel. David Muse' Debian-install kernel works fine:<pre>

1507    
1508     </pre>
1509 dpavlin 22 <li>Create a disk image which will contain the Redhat filesystem:<pre>
1510     <b>dd if=/dev/zero of=redhat_mips.img bs=1024 count=1 seek=2000000</b>
1511    
1512     </pre>
1513     <li>This is the tricky part: on redhat_mips.img, you need to create an MS-DOS
1514     (!) partition table, and then an ext2 partition. This is what Linux
1515     will then see as /dev/sda1.
1516 dpavlin 24 <p>I recommend you run fdisk and mke2fs and untar the archive from within
1517 dpavlin 22 Debian/DECstation or <a href="#debiancats">Debian/CATS</a> running
1518 dpavlin 24 inside the emulator. (Alternatively, if you are on a Linux host,
1519     you could use a loopback mount, or similar. This might require
1520     root access. See e.g.
1521     <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>.)

1536     </pre>(Note sda1 instead of sdc1.)
1537     </ol>
1538    
1539 dpavlin 22 <p>To boot Redhat linux from the disk image, use the following command line:<pre>

1808    
1809     It is (almost) possible to install and run OpenBSD/arc on an emulated Acer
1810     PICA-61 in the emulator.
1811    
1812     <p><font color="#e00000">Earlier, I had this guest OS listed as

1816    
1817     <p>
1818     <ul>
1819     <li>The last OpenBSD/arc release was 2.3. This means that it is very
1820     old, it would not give a fair picture of what OpenBSD is (if you
1821     are just looking to find out what it is like), and it is not
1822     worth experimenting with it. See
1823     <a href="http://www.openbsd.org/arc.html">http://www.openbsd.org/arc.html</a>
1824     for more information.
1825     <li>OpenBSD/arc was (if I understood things correctly) never really
1826     stable, even on real hardare. Problems with too small an interrupt
1827     stack. Bugs are triggered in the emulator that have to do with
1828     issues such as this.

1836     <font color="#e00000">Currently, I don't test for every release whether
1837     or not OpenBSD/arc can be installed. Releases prior to 0.3.7
1838     (but probably <i>not</i> 0.3.7) should work. Anyway, here are the
1839     old installation instructions:</font>
1840    
1841     <p>To install OpenBSD/arc onto an emulated harddisk image, follow these
1842     instructions:
1843    
1844     <p>
1845     <ol>
1846     <li>Create an empty harddisk image, which will be the root disk
1847     that OpenBSD installs itself onto:<pre>
1848     <b>dd if=/dev/zero of=obsd_arc.img bs=1024 count=1 seek=700000</b>
1849    
1850     </pre>
1851     <li>Download the entire arc directory from the ftp server: (approx. 75 MB)<pre>
1852     <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>
1853    
1854     </pre>
1855    
1856     <li>You now need to make an ISO image of the entire directory you downloaded.
1857     (I recommend using <tt>mkisofs</tt> for that purpose. If you don't
1858     already have <tt>mkisofs</tt> installed on your system, you need
1859     to install it in order to do this.)<pre>
1860     <b>mkisofs -o openbsd_arc_2.3.iso ftp.se.openbsd.org/pub/OpenBSD/</b>
1861    
1862     </pre>
1863     <li>Start the emulator using this command line:<pre>
1864 dpavlin 24 <b>gxemul -e pica -X -d obsd_arc.img -d b:openbsd_arc_2.3.iso -j 2.3/arc/bsd.rd</b>
1865 dpavlin 22
1866     </pre>
1867     and proceed like you would do if you were installing OpenBSD
1868     on a real Acer PICA-61. (Answer 'no' when asked if you want to
1869     configure networking, and then install from CD-ROM.)
1870     </ol>
1871    
1872     <p>
1873     Once the install has finished, the following command should let you
1874     boot from the harddisk image:
1875     <p>
1876     <pre>
1877     <b>gxemul -X -e pica -d obsd_arc.img ftp.se.openbsd.org/pub/OpenBSD/2.3/arc/bsd</b>
1878    
1879     </pre>
1880    
1881     The system is very sensitive to (I think) kernel stack overflow, so it
1882     crashes easily. If I remember correctly from mailing lists, this also
1883     happened on real hardware.

1899     Debian GNU/Linux for CATS (ARM) could <i>theoretically</i> run in GXemul,
1900     however:
1901    
1902     <ul>
1903     <li>The DEC 21143 NIC is not emulated well enough for Linux to accept it.
1904     <li>Development of Debian for CATS seems to have died? The latest

1907    
1908     <p><font color="#ff0000">IT DOES <b>NOT</b> WORK YET!</font>
1909    
1910     <p>The following installation instructions would theoretically work:
1911    
1912     <p>
1913     <ol>
1914     <li>Create an empty harddisk image, which will be the root disk
1915     that Debian installs itself onto:<pre>
1916     <b>dd if=/dev/zero of=debian_cats.img bs=1024 count=1 seek=3300000</b>
1917    
1918     </pre>
1919     <li>Download the tftpboot install kernel:<pre>
1920     <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>
1921    
1922     </pre>
1923     <li>Start the installation using the following command line:<pre>
1924     <b>gxemul -XEcats -d debian_cats.img tftpboot.img</b>
1925    
1926     </pre>
1927     </ol>
1928    
1929     <p>It doesn't work, though, because the NIC isn't working well enough.
1930    
1931     <p>The only use of Debian/CATS in the emulator right now is as a way to
1932     manipulate Linux disk images, if you are on a non-Linux host. By choosing
1933     "Execute a shell" in the installer's menu, you can have access to tools such as
1934     fdisk and mke2fs, which are useful for creating Linux paritions on disk images.

1945     <h3>Linux/QEMU_MIPS:</h3>
1946    
1947     I've added a semi-bogus machine mode which tries to

1950

1952     ramdisk kernel:
1953    
1954     <p><ol>
1955     <li>Download <a href="http://fabrice.bellard.free.fr/qemu/mips-test-0.1.tar.gz">mips-test-0.1.tar.gz</a>
1956     from <a href="http://fabrice.bellard.free.fr/qemu/download.html">http://fabrice.bellard.free.fr/qemu/download.html</a>,
1957     and extract its contents (<tt>tar zxvf mips-test-0.1.tar.gz</tt>).
1958     <p>
1959     <li>Test it in GXemul using the following command line:<pre>
1960     <b>gxemul -E qemu_mips -o 'console=ttyS0 root=/dev/ram
1961     rd_start=0x80800000 rd_size=10000000 init=/bin/sh'

1969     Sometimes QEMU is faster than GXemul, sometimes it is the other way
1970     around. A quick (and quite unfair) test on my laptop (1.8 GHz Turion ML32,
1971     I think, in AMD64 mode) comparing QEMU 0.8.1 installed as a binary package
1972     from FreeBSD ports with GXemul gave the following result:

2024     that to whatever the CDROM is called on your system,
2025     or the name of a raw .iso image. I have tried this
2026     with the Swedish version, but it might work with
2027     other versions too.)
2028     <p>
2029     <li>Create an empty harddisk image, which will be the disk image
