$Id: HISTORY,v 1.1421 2006/11/06 05:32:37 debug Exp $
20060816	Adding a framework for emulated/virtual timers (src/timer.c),
		using only setitimer().
		Rewriting the mc146818 to use the new timer framework.
20060817	Adding a call to gettimeofday() every now and then (once every
		second, at the moment) to resynch the timer if it drifts.
		Beginning to convert the ISA timer interrupt mechanism (8253
		and 8259) to use the new timer framework.
		Removing the -I command line option.
20060819	Adding the -I command line option again, with new semantics.
		Working on Footbridge timer interrupts; NetBSD/NetWinder and
		NetBSD/CATS now run at correct speed, but unfortunately with
		HUGE delays during bootup.
20060821	Some minor m68k updates. Adding the first instruction: nop. :)
		Minor Alpha emulation updates.
20060822	Adding a FreeBSD development specific YAMON environment
		variable ("khz") (as suggested by Bruce M. Simpson).
		Moving YAMON environment variable initialization from
		machine_evbmips.c into promemul/yamon.c, and adding some more
		variables.
		Continuing on the LCA PCI bus controller (for Alpha machines).
20060823	Continuing on the timer stuff: experimenting with MIPS count/
		compare interrupts connected to the timer framework.
20060825	Adding bogus SCSI commands 0x51 (SCSICDROM_READ_DISCINFO) and
		0x52 (SCSICDROM_READ_TRACKINFO) to the SCSI emulation layer,
		to allow NetBSD/pmax 4.0_BETA to be installed from CDROM.
		Minor updates to the LCA PCI controller.
20060827	Implementing a CHIP8 cpu mode, and a corresponding CHIP8
		machine, for fun. Disassembly support for all instructions,
		and most of the common instructions have been implemented: mvi,
		mov_imm, add_imm, jmp, rand, cls, sprite, skeq_imm, jsr,
		skne_imm, bcd, rts, ldr, str, mov, or, and, xor, add, sub,
		font, ssound, sdelay, gdelay, bogus skup/skpr, skeq, skne.
20060828	Beginning to convert the CHIP8 cpu in the CHIP8 machine to a
		(more correct) RCA 180x cpu. (Disassembly for all 1802
		instructions has been implemented, but no execution yet, and
		no 1805 extended instructions.)
20060829	Minor Alpha emulation updates.
20060830	Beginning to experiment a little with PCI IDE for SGI O2.
		Fixing the cursor key mappings for MobilePro 770 emulation.
		Fixing the LK201 warning caused by recent NetBSD/pmax.
		The MIPS R41xx standby, suspend, and hibernate instructions now
		behave like the RM52xx/MIPS32/MIPS64 wait instruction.
		Fixing dev_wdc so it calculates correct (64-bit) offsets before
		giving them to diskimage_access().
20060831	Continuing on Alpha emulation (OSF1 PALcode).
20060901	Minor Alpha updates; beginning on virtual memory pagetables.
		Removed the limit for max nr of devices (in preparation for
		allowing devices' base addresses to be changed during runtime).
		Adding a hack for MIPS [d]mfc0 select 0 (except the count
		register), so that the coproc register is simply copied.
		The MIPS suspend instruction now exits the emulator, instead
		of being treated as a wait instruction (this causes NetBSD/
		hpcmips to get correct 'halt' behavior).
		The VR41xx RTC now returns correct time.
		Connecting the VR41xx timer to the timer framework (fixed at
		128 Hz, for now).
		Continuing on SPARC emulation, adding more instructions:
		restore, ba_xcc, ble. The rectangle drawing demo works :)
		Removing the last traces of the old ENABLE_CACHE_EMULATION
		MIPS stuff (not usable with dyntrans anyway).
20060902	Splitting up src/net.c into several smaller files in its own
		subdirectory (src/net/).
20060903	Cleanup of the files in src/net/, to make them less ugly.
20060904	Continuing on the 'settings' subsystem.
		Minor progress on the SPARC emulation mode.
20060905	Cleanup of various things, and connecting the settings
		infrastructure to various subsystems (emul, machine, cpu, etc).
		Changing the lk201 mouse update routine to not rely on any
		emulated hardware framebuffer cursor coordinates, but instead
		always do (semi-usable) relative movements.
20060906	Continuing on the lk201 mouse stuff. Mouse behaviour with
		multiple framebuffers (which was working in Ultrix) is now
		semi-broken (but it still works, in a way).
		Moving the documentation about networking into its own file
		(networking.html), and refreshing it a bit. Adding an example
		of how to use ethernet frame direct-access (udp_snoop).
20060907	Continuing on the settings infrastructure.
20060908	Minor updates to SH emulation: for 32-bit emulation: delay
		slots and the 'jsr @Rn' instruction. I'm putting 64-bit SH5 on
		ice, for now.
20060909-10	Implementing some more 32-bit SH instructions. Removing the
		64-bit mode completely. Enough has now been implemented to run
		the rectangle drawing demo. :-)
20060912	Adding more SH instructions.
20060916	Continuing on SH emulation (some more instructions: div0u,
		div1, rotcl/rotcr, more mov instructions, dt, braf, sets, sett,
		tst_imm, dmuls.l, subc, ldc_rm_vbr, movt, clrt, clrs, clrmac).
		Continuing on the settings subsystem (beginning on reading/
		writing settings, removing bugs, and connecting more cpus to
		the framework).
20060919	More work on SH emulation; adding an ldc banked instruction,
		and attaching a 640x480 framebuffer to the Dreamcast machine
		mode (NetBSD/dreamcast prints the NetBSD copyright banner :-),
		and then panics).
20060920	Continuing on the settings subsystem.
20060921	Fixing the Footbridge timer stuff so that NetBSD/cats and
		NetBSD/netwinder boot up without the delays.
20060922	Temporarily hardcoding MIPS timer interrupt to 100 Hz. With
		'wait' support disabled, NetBSD/malta and Linux/malta run at
		correct speed.
20060923	Connecting dev_gt to the timer framework, so that NetBSD/cobalt
		runs at correct speed.
		Moving SH4-specific memory mapped registers into its own
		device (dev_sh4.c).
		Running with -N now prints "idling" instead of bogus nr of
		instrs/second (which isn't valid anyway) while idling.
20060924	Algor emulation should now run at correct speed.
		Adding disassembly support for some MIPS64 revision 2
		instructions: ext, dext, dextm, dextu.
20060926	The timer framework now works also when the MIPS wait
		instruction is used.
20060928	Re-implementing checks for coprocessor availability for MIPS
		cop0 instructions. (Thanks to Carl van Schaik for noticing the
		lack of cop0 availability checks.)
20060929	Implementing an instruction combination hack which treats
		NetBSD/pmax' idle loop as a wait-like instruction.
20060930	The ENTRYHI_R_MASK was missing in (at least) memory_mips_v2p.c,
		causing TLB lookups to sometimes succeed when they should have
		failed. (A big thank you to Juli Mallett for noticing the
		problem.)
		Adding disassembly support for more MIPS64 revision 2 opcodes
		(seb, seh, wsbh, jalr.hb, jr.hb, synci, ins, dins, dinsu,
		dinsm, dsbh, dshd, ror, dror, rorv, drorv, dror32). Also
		implementing seb, seh, dsbh, dshd, and wsbh.
		Implementing an instruction combination hack for Linux/pmax'
		idle loop, similar to the NetBSD/pmax case.
20061001	Changing the NetBSD/sgimips install instructions to extract
		files from an iso image, instead of downloading them via ftp.
20061002	More-than-31-bit userland addresses in memory_mips_v2p.c were
		not actually working; applying a fix from Carl van Schaik to
		enable them to work + making some other updates (adding kuseg
		support).
		Fixing hpcmips (vr41xx) timer initialization.
		Experimenting with O(n)->O(1) reduction in the MIPS TLB lookup
		loop. Seems to work both for R3000 and non-R3000.
20061003	Continuing a little on SH emulation (adding more control
		registers; mini-cleanup of memory_sh.c).
20061004	Beginning on a dev_rtc, a clock/timer device for the test
		machines; also adding a demo, and some documentation.
		Fixing a bug in SH "mov.w @(disp,pc),Rn" (the result wasn't
		sign-extended), and adding the addc and ldtlb instructions.
20061005	Contining on SH emulation: virtual to physical address
		translation, and a skeleton exception mechanism.
20061006	Adding more SH instructions (various loads and stores, rte,
		negc, muls.w, various privileged register-move instructions).
20061007	More SH instructions: various move instructions, trapa, div0s,
		float, fdiv, ftrc.
		Continuing on dev_rtc; removing the rtc demo.
20061008	Adding a dummy Dreamcast PROM module. (Homebrew Dreamcast
		programs using KOS libs need this.)
		Adding more SH instructions: "stc vbr,rn", rotl, rotr, fsca,
		fmul, fadd, various floating-point moves, etc. A 256-byte
		demo for Dreamcast runs :-)
20061012	Adding the SH "lds Rm,pr" and bsr instructions.
20061013	More SH instructions: "sts fpscr,rn", tas.b, and some more
		floating point instructions, cmp/str, and more moves.
		Adding a dummy dev_pvr (Dreamcast graphics controller).
20061014	Generalizing the expression evaluator (used in the built-in
		debugger) to support parentheses and +-*/%^&|.
20061015	Removing the experimental tlb index hint code in
		mips_memory_v2p.c, since it didn't really have any effect.
20061017	Minor SH updates; adding the "sts pr,Rn", fcmp/gt, fneg,
		frchg, and some other instructions. Fixing missing sign-
		extension in an 8-bit load instruction.
20061019	Adding a simple dev_dreamcast_rtc.
		Implementing memory-mapped access to the SH ITLB/UTLB arrays.
20061021	Continuing on various SH and Dreamcast things: sh4 timers,
		debug messages for dev_pvr, fixing some virtual address
		translation bugs, adding the bsrf instruction.
		The NetBSD/dreamcast GENERIC_MD kernel now reaches userland :)
		Adding a dummy dev_dreamcast_asic.c (not really useful yet).
		Implementing simple support for Store Queues.
		Beginning on the PVR Tile Accelerator.
20061022	Generalizing the PVR framebuffer to support off-screen drawing,
		multiple bit-depths, etc. (A small speed penalty, but most
		likely worth it.)
		Adding more SH instructions (mulu.w, fcmp/eq, fsub, fmac,
		fschg, and some more); correcting bugs in "fsca" and "float".
20061024	Adding the SH ftrv (matrix * vector) instruction. Marcus
		Comstedt's "tatest" example runs :) (wireframe only).
		Correcting disassembly for SH floating point instructions that
		use the xd* registers.
		Adding the SH fsts instruction.
		In memory_device_dyntrans_access(), only the currently used
		range is now invalidated, and not the entire device range.
20061025	Adding a dummy AVR32 cpu mode skeleton.
20061026	Various Dreamcast updates; beginning on a Maple bus controller.
20061027	Continuing on the Maple bus. A bogus Controller, Keyboard, and
		Mouse can now be detected by NetBSD and KOS homebrew programs.
		Cleaning up the SH4 Timer Management Unit, and beginning on
		SH4 interrupts.
		Implementing the Dreamcast SYSASIC.
20061028	Continuing on the SYSASIC.
		Adding the SH fsqrt instruction.
		memory_sh.c now actually scans the ITLB.
		Fixing a bug in dev_sh4.c, related to associative writes into
		the memory-mapped UTLB array. NetBSD/dreamcast now reaches
		userland stably, and prints the "Terminal type?" message :-]
		Implementing enough of the Dreamcast keyboard to make NetBSD
		accept it for input.
		Enabling SuperH for stable (non-development) builds.
		Adding NetBSD/dreamcast to the documentation, although it
		doesn't support root-on-nfs yet.
20061029	Changing usleep(1) calls in the debugger to to usleep(10000)
		(according to Brian Foley, this makes GXemul run better on
		MacOS X).
		Making the Maple "Controller" do something (enough to barely
		interact with dcircus.elf).
20061030-31	Some progress on the PVR. More test programs start running (but
		with strange output).
		Various other SH4-related updates.
20061102	Various Dreamcast and SH4 updates; more KOS demos run now.
20061104	Adding a skeleton dev_mb8696x.c (the Dreamcast's LAN adapter).
20061105	Continuing on the MB8696x; NetBSD/dreamcast detects it as mbe0.
		Testing for the release.

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

109 dpavlin 24 </ul>
110 dpavlin 2
111 dpavlin 24 <p>Some operating systems are listed with a version number <i>less</i>
112     than what was available at the time of this GXemul release (e.g.
113     NetBSD/prep). The reasons for this is because of incompleteness in
114     GXemul's machine, device, and/or processor implementations.
115 dpavlin 2

124 dpavlin 10 <h3>NetBSD/pmax:</h3>
125 dpavlin 2
126 dpavlin 24 <p><a href="http://www.netbsd.org/Ports/pmax/">NetBSD/pmax</a> was the
127 dpavlin 28 first guest OS that could be
128     <a href="http://mail-index.netbsd.org/port-pmax/2004/04/18/0000.html">installed</a>
129     onto a disk image in GXemul. The device emulation of the DECstation
130     5000/200 is reasonably complete; it should be enough to emulate a
131     networked X-windows-capable workstation.
132 dpavlin 24
133 dpavlin 32 <p>NetBSD/pmax 1.6.2 works perfectly with X out-of-the-box. Unfortunately,
134     newer NetBSD releases have changed slightly, and X does not work straight
135     away with NetBSD 2.x and 3.x. It seems that this has to do with NetBSD
136     switching console system to "WSCONS" somewhere between 1.6.2 and 2.0.
137 dpavlin 24
138 dpavlin 32 <p>What this means is that if you want to use emulated X11, then you need
139     to run NetBSD 1.6.2. At the time of writing this, 4.0_BETA snapshots work
140     fine too, but 4.0 isn't released yet. If you feel that you only need
141     serial-console emulation, then choose 3.1.
142    
143 dpavlin 24 <p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
144 dpavlin 6 <a href="20050317-example.png"><img src="20050317-example_small.png"></a>
145 dpavlin 4
146 dpavlin 24 <p>To install NetBSD/pmax onto a harddisk image in the emulator,
147     follow these instructions:
148 dpavlin 2
149 dpavlin 10 <p><ol start="1">
150 dpavlin 2 <li>Create an empty harddisk image, which will be the root disk
151     that NetBSD installs itself onto:<pre>
152 dpavlin 32 <b>dd if=/dev/zero of=nbsd_pmax.img bs=1024 count=1 seek=3000000</b>
153 dpavlin 2
154     </pre>
155     </ol>
156 dpavlin 4
157 dpavlin 2 <p>
158     From this point, there are two separate ways to continue the installation.
159     You can either download a CD-ROM iso image (and let the installation
160     program copy files from the CD-ROM image to the harddisk image), or you
161     can install via ftp. For an installation from a CD-ROM image, follow these
162     steps:
163     <p>
164     <ol start="2">
165    
166     <li>Download a NetBSD CD-ROM iso image:<pre>
167 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>
168 dpavlin 2 or
169 dpavlin 32 <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>
170 dpavlin 2
171     </pre>
172     <li>Start the emulator like this:<pre>
173 dpavlin 32 <b>gxemul -e 3max -d nbsd_pmax.img -d bc:pmaxcd-3.1.iso</b>
174 dpavlin 22 (or <b>pmaxcd.iso</b>)
175 dpavlin 2 </pre>
176 dpavlin 10 and proceed like you would do if you were installing NetBSD on a real
177 dpavlin 12 DECstation. Remember to choose <tt>vt100</tt> as your terminal
178     type, and not <tt>rcons</tt>.
179 dpavlin 2 </ol>
180     <p>
181     For an ftp install, substitute steps 2 and 3 above with these:
182     <p>
183     <ol start="2">

544     <p>One way to install the NetBSD/algor distribution onto a disk

546    
547     <p>The following instructions will let you install NetBSD/algor onto a disk
548     image, from an emulated DECstation 3MAX machine:
549    
550     <p>

554 dpavlin 30 </pre>
555     <p>
556     <li>Create an empty harddisk image, which will be the disk image

571     <li>At the <tt>Terminal type? [rcons]</tt> prompt, type <b>CTRL-B</b>

590    
591     <p>The installation instructions above create a filesystem
592     <i>without</i> a disklabel, so there is only one ffs partition and no

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

987    
988     <p>Note: The installation instructions above create a filesystem

1000     <ul>
1001     <li>There is a long delay when starting up NetBSD/netwinder
1002     (several seconds even on a very fast host machine),
1003     so you need to be patient.
1004     <li>There is a minor bug in the keyboard device, so you need to
1005     press a key (any key) before typing wd0c.
1006     <li>When halting/rebooting NetBSD/netwinder, the emulator
1007     prints a message saying something about an internal
1008     error. This doesn't matter; ignore the message.

1181    
1182     <p>
1183 dpavlin 2 OpenBSD/pmax died at release 2.8 of OpenBSD, so you should be
1184     aware of the fact that this will not give you an up-to-date OpenBSD
1185     system.
1186    
1187     <p>
1188     Following these instructions <i>might</i> work. If not, then use
1189     common sense and imagination to modify them as you see fit.
1190    
1191     <p>
1192     <ol>
1193     <li>Create an empty harddisk image, which will be the root disk
1194     that OpenBSD installs itself onto:<pre>

1208     </pre></td></tr></table>
1209 dpavlin 2 <li>You now need to make an ISO image of the entire directory you downloaded.
1210 dpavlin 10 (I recommend using <tt>mkisofs</tt> for that purpose. If you don't
1211 dpavlin 6 already have <tt>mkisofs</tt> installed on your system, you need
1212 dpavlin 10 to install it in order to do this.)<pre>

1219 dpavlin 2
1220     </pre>
1221 dpavlin 12 (If you add <tt>-X</tt>, you will run with the graphical
1222 dpavlin 6 framebuffer. This is <i>REALLY</i> slow because the console has to
1223     scroll a lot during the install. I don't recommend it.)
1224 dpavlin 2 <p>
1225     <li>Go on with the installation as you would do if you were installing on a real machine.
1226     If you are not used to the OpenBSD installer, then this will most likely
1227     be a very uncomfortable experience. Some important things to keep in mind are:
1228     <ul>
1229     <li>rz0 is the rootdisk you wish to install onto.
1230     <li>rz1 is the simpleroot image.
1231     <li>rz2 is the CDROM containing the "install sets".
1232     <li>When asked for the "<b>root device?</b>", enter <b>rz1</b>.
1233     <li>At "<b>Enter pathname of shell or RETURN for sh:</b>", press enter.
1234     <li>At the # prompt, do the following:<pre>
1235 dpavlin 12 <b>fsck /dev/rz1a</b> (and mark the filesystem as clean)
1236     <b>mount /dev/rz1a /</b>
1237     <b>mount -t kernfs kern kern</b>
1238     <b>./install</b>
1239 dpavlin 2
1240     </pre>
1241     and proceed with the install. Good luck. :-)
1242     <li>Answer "<b>y</b>" when asked if you wish to configure the network.
1243     (See the section about installing NetBSD/pmax for suitable
1244     network settings.)
1245     <li>Install from "<b>c</b>" (cdrom), choose "<b>rz2</b>" as the cdrom device, and "<b>/</b>" as
1246     the directory containing the install sets.
1247     </ul>
1248     <p>
1249 dpavlin 10 <li>For some unknown reason, the install script does not set the root
1250     password! The first time you boot up OpenBSD after the install, you
1251     need to go into single user mode and run <b>passwd root</b> to set
1252     the root password, or you will not be able to log in at all!<pre>
1253 dpavlin 24 <b>gxemul -e 3max -d obsd_pmax.img -d 2c:openbsd_pmax_2.8.iso -j bsd -o '-s'</b>
1254 dpavlin 2 </pre>
1255     While you are at it, you might want to extract the X11 install sets
1256     as well, as the installer seems to ignore them too. (Perhaps due to a bug
1257     in the installer, perhaps because of the way I used mkisofs.)
1258     <p>
1259     Execute the following commands in the emulator:

1342     (I recommend using <tt>mkisofs</tt> for that purpose. If you don't

1360     nameserver 10.0.0.254, the userland NAT-like networking layer is not

1396     The following instructions should let you install Ultrix onto a disk image:
1397    
1398 dpavlin 2 <ol>
1399     <li>Create an empty harddisk image, which will be the root disk
1400     that Ultrix installs itself onto:<pre>
1401 dpavlin 12 <b>dd if=/dev/zero of=rootdisk.img bs=1024 count=1 seek=800000</b>
1402 dpavlin 2
1403     </pre>
1404 dpavlin 6 <li>Place your Ultrix installation media in your CDROM drive.
1405     (On FreeBSD and similar systems, it is called <tt>/dev/cd0c</tt>.
1406     Replace that with the name of your CDROM drive, or the name of a
1407     .iso image file.) Then, start the emulator like this:<pre>
1408 dpavlin 24 <b>gxemul -X -e 3max -d rootdisk.img -d bc:/dev/cd0c -j vmunix</b>
1409 dpavlin 2
1410     </pre>
1411     <li>Once the first stage of the installation is done (restoring the root
1412     filesystem), you need to restart the emulator, booting from the
1413     new rootdisk, to continue the installation process.
1414 dpavlin 6 This is done by removing the bootflag ('<tt>b</tt>') from the second
1415 dpavlin 2 diskimage argument:<pre>
1416 dpavlin 24 <b>gxemul -X -e 3max -d rootdisk.img -d c:/dev/cd0c -j vmunix</b>

1418     </pre>
1419     </ol>
1420    
1421     <p>
1422     When the installation is completed, the following command should start
1423     Ultrix from the harddisk image:<pre>
1424 dpavlin 24 <b>gxemul -X -e 3max -j vmunix -d rootdisk.img</b>
1425 dpavlin 2 </pre>
1426    
1427 dpavlin 24 <p>If you have a very fast host machine, you might experience a weird
1428 dpavlin 10 timer related bug, which makes it impossible to logon to the system. It is
1429     triggered when the emulation goes faster than any real DECstation machine
1430     was capable of running. A temporary workaround is to add
1431     <b><tt>-I33000000</tt></b> to fix the emulated clock speed to 33 million
1432 dpavlin 32 instructions per emulated second.
1433 dpavlin 2
1434 dpavlin 32 <p>If the workaround above doesn't work, you can also start up other
1435     processes on the host, apart from the emulator, so that the emulator runs
1436     more slowly. This is an ugly workaround, but seems to work. Once you have
1437     logged in into Ultrix, you can kill the extra processes.
1438    
1439     <p>You can experiment with adding <b><tt>-Z2</tt></b> (for emulating a
1440 dpavlin 6 dual-headed workstation) or even <b><tt>-Z3</tt></b> (tripple-headed), and
1441     also the <b><tt>-Y2</tt></b> option for scaling down the framebuffer
1442     windows by a factor 2x2.
1443     There is also a <b><tt>-z</tt></b> option for supplying names of X11
1444     displays to use. The following example starts Ultrix on an emulated
1445     tripple-headed workstation, on three different displays (<tt>remote1:0.0</tt>,
1446     <tt>localhost:0.0</tt>, and <tt>remote2:0.0</tt>), using no scaledown:<pre>
1447 dpavlin 24 <b>gxemul -N -e 3max -jgenvmunix -d rootdisk.img \
1448 dpavlin 6 -XZ3 -z remote1:0.0 -z localhost:0.0 -z remote2:0.0</b>
1449 dpavlin 2 </pre>
1450    
1451 dpavlin 32 <p>The photo below shows a single Ultrix session running tripple-headed in
1452 dpavlin 6 GXemul on an Alpha 21164PC, with displays on a Sun Ultra1 (to the left),
1453     on the Alpha itself (in the middle), and on an HP700/RX X-terminal (8-bit
1454     color depth, running off the Alpha) to the right.

1457 dpavlin 6 <a href="20041209-ultrix-tripplehead.jpg"><img src="20041209-ultrix-tripplehead_small.jpg"></a>
1458    
1459 dpavlin 32 <p>The X11 displays may differ in bit depth and endianness. Unfortunately,
1460 dpavlin 2 there is no way yet to set the scaledown factor on a per-window basis, so
1461     the scaledown factor affects all windows.
1462    
1463 dpavlin 32 <p>(If you didn't use <tt><b>-Z<i>n</i></b></tt> during the installation, and
1464 dpavlin 6 compiled your own <tt>/vmunix</tt>, then it will not contain support for
1465     multiple graphics cards. To overcome this problem, use the generic kernel,
1466     <tt><b>-j genvmunix</b></tt>, whenever you are running the emulator with a
1467     different setup than the one you used when Ultrix was installed.)
1468 dpavlin 2
1469 dpavlin 32 <p>A note for the historically interested: OSF/1 for MIPS was quite similar
1470 dpavlin 4 to Ultrix, so that is possible to run as well. If you are unsuccessful
1471     in installing Ultrix or OSF/1 directly in the emulator, you can always
1472     install it on your real machine onto a real SCSI disk, and then copy the
1473 dpavlin 6 contents of that SCSI disk into a file (using <b><tt>dd(1)</tt></b>), and use
1474 dpavlin 4 that file as a disk image file in the emulator.

1547 dpavlin 10 <h3>Debian GNU/Linux for DECstation:</h3>
1548 dpavlin 2
1549 dpavlin 22 It is possible to run Debian GNU/Linux for DECstation in the emulator,
1550 dpavlin 32 on an emulated 5000/200 ("3max"). However, just choosing any
1551     Linux/DECstation kernel at random for the installation will not work.
1552    
1553     <p><ul>
1554     <li>Linux 2.4/DECstation DZ serial console output doesn't work too well in
1555     GXemul. Linux oopses randomly, which may be due to bugs in GXemul,
1556     but may also be due to bugs in the serial controller code in Linux.
1557 dpavlin 22 (The speed at which serial interrupts are generated can be
1558     lowered with the <tt>-U</tt> command line option, but it only
1559     reduces the risk, it doesn't take away the oopses completely.)
1560 dpavlin 32 <li>The Linux 2.6/DECstation DZ serial console driver doesn't work at
1561     all in the emulator, and I'm not really sure it would work on a
1562     real 5000/200 either. Hopefully this will be fixed in Linux in
1563     the future.
1564     <li>To get around the serial console problem, the obvious solution is to
1565     use a graphical framebuffer instead. Old Debian install kernels
1566     supported the graphical framebuffer on the 3max, but not the
1567     keyboard. (This has been fixed now, it seems.)
1568     <li>For quite some time, the MIPS linux cvs tree has had support for the
1569     framebuffer and keyboard, but it did not include Debian's
1570     patches for networking, which made it unusable for network
1571     installs. (Possibly fixed now.)
1572     <li>The kernel has to be for 5000/200. This rules out using
1573     the default kernel on netinst ISO images provided by Debian.
1574     These ISO images boot directly into a kernel which is meant
1575     for a different DECstation model.
1576     <li>The kernel has to have an initrd which more or less matches the
1577     version of Debian that will be installed.
1578 dpavlin 22 </ul>
1579 dpavlin 10
1580 dpavlin 32 <p>Luckily, a precompiled install kernel has been made available by David
1581     Muse, for Debian for R3000 DECstations, which has support for framebuffer,
1582     keyboard, and networking, which works pretty well. Thanks David. :-)
1583 dpavlin 2
1584 dpavlin 32 <p>The following steps should let you install Debian GNU/Linux for
1585     DECstation onto a harddisk image in the emulator:
1586 dpavlin 2
1587     <p>

1709    
1710     </pre>
1711     <li>This is the tricky part: on redhat_mips.img, you need to create an MS-DOS
1712     (!) partition table, and then an ext2 partition. This is what Linux
1713     will then see as /dev/sda1.
1714 dpavlin 24 <p>I recommend you run fdisk and mke2fs and untar the archive from within
1715 dpavlin 22 Debian/DECstation or <a href="#debiancats">Debian/CATS</a> running
1716 dpavlin 24 inside the emulator. (Alternatively, if you are on a Linux host,
1717     you could use a loopback mount, or similar. This might require
1718     root access. See e.g.

2006    
2007     It is (almost) possible to install and run OpenBSD/arc on an emulated Acer
2008     PICA-61 in the emulator.
2009    
2010     <p><font color="#e00000">Earlier, I had this guest OS listed as
2011     officially working in the emulator, but for several reasons, it has

2013     section.</font>
2014    
2015     <p>
2016     <ul>
2017     <li>The last OpenBSD/arc release was 2.3. This means that it is very
2018     old, it would not give a fair picture of what OpenBSD is (if you
2019     are just looking to find out what it is like), and it is not
2020     worth experimenting with it. See
2021     <a href="http://www.openbsd.org/arc.html">http://www.openbsd.org/arc.html</a>
2022     for more information.
2023     <li>OpenBSD/arc was (if I understood things correctly) never really
2024     stable, even on real hardare. Problems with too small an interrupt
2025     stack. Bugs are triggered in the emulator that have to do with
2026     issues such as this.

2033     <p>
2034     <font color="#e00000">Currently, I don't test for every release whether
2035     or not OpenBSD/arc can be installed. Releases prior to 0.3.7
2036     (but probably <i>not</i> 0.3.7) should work. Anyway, here are the
2037     old installation instructions:</font>
2038    
2039     <p>To install OpenBSD/arc onto an emulated harddisk image, follow these
2040     instructions:
2041    
2042     <p>
2043     <ol>
2044     <li>Create an empty harddisk image, which will be the root disk
2045     that OpenBSD installs itself onto:<pre>
2046     <b>dd if=/dev/zero of=obsd_arc.img bs=1024 count=1 seek=700000</b>
2047    
2048     </pre>
2049     <li>Download the entire arc directory from the ftp server: (approx. 75 MB)<pre>
2050     <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>
2051    
2052     </pre>
2053    
2054     <li>You now need to make an ISO image of the entire directory you downloaded.
2055     (I recommend using <tt>mkisofs</tt> for that purpose. If you don't
2056     already have <tt>mkisofs</tt> installed on your system, you need
2057     to install it in order to do this.)<pre>
2058     <b>mkisofs -o openbsd_arc_2.3.iso ftp.se.openbsd.org/pub/OpenBSD/</b>
2059    
2060     </pre>
2061     <li>Start the emulator using this command line:<pre>
2062 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>
2063 dpavlin 22
2064     </pre>
2065     and proceed like you would do if you were installing OpenBSD
2066     on a real Acer PICA-61. (Answer 'no' when asked if you want to
2067     configure networking, and then install from CD-ROM.)
2068     </ol>
2069    
2070     <p>
2071     Once the install has finished, the following command should let you
2072     boot from the harddisk image:
2073     <p>
2074     <pre>
2075     <b>gxemul -X -e pica -d obsd_arc.img ftp.se.openbsd.org/pub/OpenBSD/2.3/arc/bsd</b>
2076    
2077     </pre>
2078    
2079     The system is very sensitive to (I think) kernel stack overflow, so it
2080     crashes easily. If I remember correctly from mailing lists, this also
2081     happened on real hardware.

2100     <ul>
2101     <li>The DEC 21143 NIC is not emulated well enough for Linux to accept it.
2102     <li>Development of Debian for CATS seems to have died? The latest

2106     <p><font color="#ff0000">IT DOES <b>NOT</b> WORK YET!</font>
2107    
2108     <p>The following installation instructions would theoretically work:
2109

2112     <li>Create an empty harddisk image, which will be the root disk
2113     that Debian installs itself onto:<pre>
2114     <b>dd if=/dev/zero of=debian_cats.img bs=1024 count=1 seek=3300000</b>

2121     <li>Start the installation using the following command line:<pre>
2122     <b>gxemul -XEcats -d debian_cats.img tftpboot.img</b>
2123    
2124     </pre>
2125     </ol>
2126    
2127     <p>It doesn't work, though, because the NIC isn't working well enough.
2128    
2129     <p>The only use of Debian/CATS in the emulator right now is as a way to
2130     manipulate Linux disk images, if you are on a non-Linux host. By choosing
2131     "Execute a shell" in the installer's menu, you can have access to tools such as
2132     fdisk and mke2fs, which are useful for creating Linux paritions on disk images.

2382     <a href="ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-2.1/prep/binary/kernel/netbsd-INSTALL.gz">ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-2.1/prep/binary/kernel/netbsd-INSTALL.gz</a>
2383     </pre>
2384     <p>
2385     <li>Create an empty harddisk image, which will be the disk image
2386     that you will install NetBSD onto:<pre>
2387     <b>dd if=/dev/zero of=nbsd_bebox.img bs=1024 count=1 seek=999000</b>
2388     </pre>
2389     <p>
2390     <li>Download the NetBSD/bebox snapshot, and create a suitable .iso
2391     image of the files:
2392     <p><table border="0"><tr><td><tt>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</tt></td><td><pre>
2393     <b>wget -np -l 0 -r <a href="ftp://ftp.netbsd.org/pub/NetBSD/arch/bebox/snapshot/19981119/">ftp://ftp.netbsd.org/pub/NetBSD/arch/bebox/snapshot/19981119/</a>
2394     mv ftp.netbsd.org/pub/NetBSD/arch/bebox/snapshot/19981119/kern.tgz .
2395     tar zxvf kern.tgz
2396     rm -f kern.tgz
2397     mkisofs -o netbsd-bebox-19981119.iso ftp.netbsd.org/pub/NetBSD/arch/bebox/snapshot/19981119</b>
2398     </pre></td></tr></table>
2399     <p>
2400     <li>Now let's extract the files onto the Bebox disk image. Start NetBSD/prep
2401     with the following command line:<pre>
2402     <b>gxemul -x -e ibm6050 -d d:netbsd-bebox-19981119.iso -d nbsd_bebox.img netbsd-INSTALL.gz</b>
2403    
2404     </pre>Choose (S) for Shell, and execute the following commands:
2405     <p><table border="0"><tr><td><tt>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</tt></td><td><pre>
2406     <b>disklabel -I -i wd1

2427     cd /; umount /mnt; umount /mnt2
2428     sync; halt</b>
2429     </pre></td></tr></table>
2430     </ol>
2431    
2432     <p>You should now be able to boot NetBSD/bebox using this command:<pre>
2433     <b>gxemul -X -E bebox -d nbsd_bebox.img netbsd</b>
2434     </pre>
2435    
2436     <p>When asked for the root device, enter <b><tt>wd0a</tt></b>.
2437    
2438     <p><font color="#ff0000">IT DOES <b>NOT</b> WORK YET</font>, there are
2439     errors while uncompressing the tgz files, and the machine crashes when
2440     trying to run /sbin/init.
