$Id: HISTORY,v 1.1256 2006/06/23 20:43:44 debug Exp $
20060219	Various minor updates. Removing the old MIPS16 skeleton code,
		because it will need to be rewritten for dyntrans anyway.
20060220-22	Removing the non-working dyntrans backend support.
		Continuing on the 64-bit dyntrans virtual memory generalization.
20060223	More work on the 64-bit vm generalization.
20060225	Beginning on MIPS dyntrans load/store instructions.
		Minor PPC updates (64-bit load/store, etc).
		Fixes for the variable-instruction-length framework, some
		minor AVR updates (a simple Hello World program works!).
		Beginning on a skeleton for automatically generating documen-
		tation (for devices etc.).
20060226	PPC updates (adding some more 64-bit instructions, etc).
		AVR updates (more instructions).
		FINALLY found and fixed the zs bug, making NetBSD/macppc
		accept the serial console.
20060301	Adding more AVR instructions.
20060304	Continuing on AVR-related stuff. Beginning on a framework for
		cycle-accurate device emulation. Adding an experimental "PAL
		TV" device (just a dummy so far).
20060305	Adding more AVR instructions.
		Adding a dummy epcom serial controller (for TS7200 emulation).
20060310	Removing the emul() command from configuration files, so only
		net() and machine() are supported.
		Minor progress on the MIPS dyntrans rewrite.
20060311	Continuing on the MIPS dyntrans rewrite (adding more
		instructions, etc).
20060315	Adding more instructions (sllv, srav, srlv, bgtz[l], blez[l],
		beql, bnel, slti[u], various loads and stores).
20060316	Removing the ALWAYS_SIGNEXTEND_32 option, since it was rarely
		used.
		Adding more MIPS dyntrans instructions, and fixing bugs.
20060318	Implementing fast loads/stores for MIPS dyntrans (big/little
		endian, 32-bit and 64-bit modes).
20060320	Making MIPS dyntrans the default configure option; use
		"--enable-oldmips" to use the old bintrans system.
		Adding MIPS dyntrans dmult[u]; minor updates.
20060322	Continuing... adding some more instructions.
		Adding a simple skeleton for demangling C++ "_ZN" symbols.
20060323	Moving src/debugger.c into a new directory (src/debugger/).
20060324	Fixing the hack used to load PPC ELFs (useful for relocated
		Linux/ppc kernels), and adding a dummy G3 machine mode.
20060325-26	Beginning to experiment with GDB remote serial protocol
		connections; adding a -G command line option for selecting
		which TCP port to listen to.
20060330	Beginning a major cleanup to replace things like "0x%016llx"
		with more correct "0x%016"PRIx64, etc.
		Continuing on the GDB remote serial protocol support.
20060331	More cleanup, and some minor GDB remote progress.
20060402	Adding a hack to the configure script, to allow compilation
		on systems that lack PRIx64 etc.
20060406	Removing the temporary FreeBSD/arm hack in dev_ns16550.c and
		replacing it with a better fix from Olivier Houchard.
20060407	A remote debugger (gdb or ddd) can now start and stop the
		emulator using the GDB remote serial protocol, and registers
		and memory can be read. MIPS only for now.
20060408	More GDB progress: single-stepping also works, and also adding
		support for ARM, PowerPC, and Alpha targets.
		Continuing on the delay-slot-across-page-boundary issue.
20060412	Minor update: beginning to add support for the SPARC target
		to the remote GDB functionality.
20060414	Various MIPS updates: adding more instructions for dyntrans
		(eret, add), and making some exceptions work. Fixing a bug
		in dmult[u].
		Implementing the first SPARC instructions (sethi, or).
20060415	Adding "magic trap" instructions so that PROM calls can be
		software emulated in MIPS dyntrans.
		Adding more MIPS dyntrans instructions (ddiv, dadd) and
		fixing another bug in dmult.
20060416	More MIPS dyntrans progress: adding [d]addi, movn, movz, dsllv,
		rfi, an ugly hack for supporting R2000/R3000 style faked caches,
		preliminary interrupt support, and various other updates and
		bugfixes.
20060417	Adding more SPARC instructions (add, sub, sll[x], sra[x],
		srl[x]), and useful SPARC header definitions.
		Adding the first (trivial) x86/AMD64 dyntrans instructions (nop,
		cli/sti, stc/clc, std/cld, simple mov, inc ax). Various other
		x86 updates related to variable instruction length stuff.
		Adding unaligned loads/stores to the MIPS dyntrans mode (but
		still using the pre-dyntrans (slow) imlementation).
20060419	Fixing a MIPS dyntrans exception-in-delay-slot bug.
		Removing the old "show opcode statistics" functionality, since
		it wasn't really useful and isn't implemented for dyntrans.
		Single-stepping (or running with instruction trace) now looks
		ok with dyntrans with delay-slot architectures.
20060420	Minor hacks (removing the -B command line option when compiled
		for non-bintrans, and some other very minor updates).
		Adding (slow) MIPS dyntrans load-linked/store-conditional.
20060422	Applying fixes for bugs discovered by Nils Weller's nwcc
		(static DEC memmap => now per machine, and adding an extern
		keyword in cpu_arm_instr.c).
		Finally found one of the MIPS dyntrans bugs that I've been
		looking for (copy/paste spelling error BIG vs LITTLE endian in
		cpu_mips_instr_loadstore.c for 16-bit fast stores).
		FINALLY found the major MIPS dyntrans bug: slti vs sltiu
		signed/unsigned code in cpu_mips_instr.c. :-)
		Adding more MIPS dyntrans instructions (lwc1, swc1, bgezal[l],
		ctc1, tlt[u], tge[u], tne, beginning on rdhwr).
		NetBSD/hpcmips can now reach userland when using dyntrans :-)
		Adding some more x86 dyntrans instructions.
		Finally removed the old Alpha-specific virtual memory code,
		and replaced it with the generic 64-bit version.
		Beginning to add disassembly support for SPECIAL3 MIPS opcodes.
20060423	Continuing on the delay-slot-across-page-boundary issue;
		adding an end_of_page2 ic slot (like I had planned before, but
		had removed for some reason).
		Adding a quick-and-dirty fallback to legacy coprocessor 1
		code (i.e. skipping dyntrans implementation for now).
		NetBSD/hpcmips and NetBSD/pmax (when running on an emulated
		R4400) can now be installed and run. :-)  (Many bugs left
		to fix, though.)
		Adding more MIPS dyntrans instructions: madd[u], msub[u].
		Cleaning up the SPECIAL2 vs R5900/TX79/C790 "MMI" opcode
		maps somewhat (disassembly and dyntrans instruction decoding).
20060424	Adding an isa_revision field to mips_cpu_types.h, and making
		sure that SPECIAL3 opcodes cause Reserved Instruction
		exceptions on MIPS32/64 revisions lower than 2.
		Adding the SPARC 'ba', 'call', 'jmpl/retl', 'and', and 'xor'
		instructions.
20060425	Removing the -m command line option ("run at most x 
		instructions") and -T ("single_step_on_bad_addr"), because
		they never worked correctly with dyntrans anyway.
		Freshening up the man page.
20060428	Adding more MIPS dyntrans instructions: bltzal[l], idle.
		Enabling MIPS dyntrans compare interrupts.
20060429	FINALLY found the weird dyntrans bug, causing NetBSD etc. to
		behave strangely: some floating point code (conditional
		coprocessor branches) could not be reused from the old
		non-dyntrans code. The "quick-and-dirty fallback" only appeared
		to work. Fixing by implementing bc1* for MIPS dyntrans.
		More MIPS instructions: [d]sub, sdc1, ldc1, dmtc1, dmfc1, cfc0.
		Freshening up MIPS floating point disassembly appearance.
20060430	Continuing on C790/R5900/TX79 disassembly; implementing 128-bit
		"por" and "pextlw".
20060504	Disabling -u (userland emulation) unless compiled as unstable
		development version.
		Beginning on freshening up the testmachine include files,
		to make it easier to reuse those files (placing them in
		src/include/testmachine/), and beginning on a set of "demos"
		or "tutorials" for the testmachine functionality.
		Minor updates to the MIPS GDB remote protocol stub.
		Refreshing doc/experiments.html and gdb_remote.html.
		Enabling Alpha emulation in the stable release configuration,
		even though no guest OSes for Alpha can run yet.
20060505	Adding a generic 'settings' object, which will contain
		references to settable variables (which will later be possible
		to access using the debugger).
20060506	Updating dev_disk and corresponding demo/documentation (and
		switching from SCSI to IDE disk types, so it actually works
		with current test machines :-).
20060510	Adding a -D_LARGEFILE_SOURCE hack for 64-bit Linux hosts,
		so that fseeko() doesn't give a warning.
		Updating the section about how dyntrans works (the "runnable
		IR") in doc/intro.html.
		Instruction updates (some x64=1 checks, some more R5900
		dyntrans stuff: better mul/mult separation from MIPS32/64,
		adding ei and di).
		Updating MIPS cpuregs.h to a newer one (from NetBSD).
		Adding more MIPS dyntrans instructions: deret, ehb.
20060514	Adding disassembly and beginning implementation of SPARC wr
		and wrpr instructions.
20060515	Adding a SUN SPARC machine mode, with dummy SS20 and Ultra1
		machines. Adding the 32-bit "rd psr" instruction.
20060517	Disassembly support for the general SPARC rd instruction.
		Partial implementation of the cmp (subcc) instruction.
		Some other minor updates (making sure that R5900 processors
		start up with the EIE bit enabled, otherwise Linux/playstation2
		receives no interrupts).
20060519	Minor MIPS updates/cleanups.
20060521	Moving the MeshCube machine into evbmips; this seems to work
		reasonably well with a snapshot of a NetBSD MeshCube kernel.
		Cleanup/fix of MIPS config0 register initialization.
20060529	Minor MIPS fixes, including a sign-extension fix to the
		unaligned load/store code, which makes NetBSD/pmax on R3000
		work better with dyntrans. (Ultrix and Linux/DECstation still
		don't work, though.)
20060530	Minor updates to the Alpha machine mode: adding an AlphaBook
		mode, an LCA bus (forwarding accesses to an ISA bus), etc.
20060531	Applying a bugfix for the MIPS dyntrans sc[d] instruction from
		Ondrej Palkovsky. (Many thanks.)
20060601	Minifix to allow ARM immediate msr instruction to not give
		an error for some valid values.
		More Alpha updates.
20060602	Some minor Alpha updates.
20060603	Adding the Alpha cmpbge instruction. NetBSD/alpha prints its
		first boot messages :-) on an emulated Alphabook 1.
20060612	Minor updates; adding a dev_ether.h include file for the
		testmachine ether device. Continuing the hunt for the dyntrans
		bug which makes Linux and Ultrix on DECstation behave
		strangely... FINALLY found it! It seems to be related to
		invalidation of the translation cache, on tlbw{r,i}. There
		also seems to be some remaining interrupt-related problems.
20060614	Correcting the implementation of ldc1/sdc1 for MIPS dyntrans
		(so that it uses 16 32-bit registers if the FR bit in the
		status register is not set).
20060616	REMOVING BINTRANS COMPLETELY!
		Removing the old MIPS interpretation mode.
		Removing the MFHILO_DELAY and instruction delay stuff, because
		they wouldn't work with dyntrans anyway.
20060617	Some documentation updates (adding "NetBSD-archive" to some
		URLs, and new Debian/DECstation installation screenshots).
		Removing the "tracenull" and "enable-caches" configure options.
		Improving MIPS dyntrans performance somewhat (only invalidate
		translations if necessary, on writes to the entryhi register,
		instead of doing it for all cop0 writes).
20060618	More cleanup after the removal of the old MIPS emulation.
		Trying to fix the MIPS dyntrans performance bugs/bottlenecks;
		only semi-successful so far (for R3000).
20060620	Minor update to allow clean compilation again on Tru64/Alpha.
20060622	MIPS cleanup and fixes (removing the pc_last stuff, which
		doesn't make sense with dyntrans anyway, and fixing a cross-
		page-delay-slot-with-exception case in end_of_page).
		Removing the old max_random_cycles_per_chunk stuff, and the
		concept of cycles vs instructions for MIPS emulation.
		FINALLY found and fixed the bug which caused NetBSD/pmax
		clocks to behave strangely (it was a load to the zero register,
		which was treated as a NOP; now it is treated as a load to a
		dummy scratch register).
20060623	Increasing the dyntrans chunk size back to
		N_SAFE_DYNTRANS_LIMIT, instead of N_SAFE_DYNTRANS_LIMIT/2.
		Preparing for a quick release, even though there are known
		bugs, and performance for non-R3000 MIPS emulation is very
		poor. :-/
		Reverting to half the dyntrans chunk size again, because
		NetBSD/cats seemed less stable with full size chunks. :(
		NetBSD/sgimips 3.0 can now run :-)  (With release 0.3.8, only
		NetBSD/sgimips 2.1 worked, not 3.0.)

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
96 dpavlin 24 <ul>

102     <li><a href="#netbsdmacppcinstall">NetBSD/macppc 3.0</a>
103     </ul>
104 dpavlin 2
105 dpavlin 24 <p>Some operating systems are listed with a version number <i>less</i>
106     than what was available at the time of this GXemul release (e.g.
107     NetBSD/prep). The reasons for this is because of incompleteness in
108     GXemul's machine, device, and/or processor implementations.

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

555 dpavlin 24 <li>The dynamic translation core runs faster when emulating 32-bit
556     processors, so <tt><b>-C 4Kc</b></tt> might make things go faster.
557 dpavlin 20 <li>4Kc only has 16 TLB entries, whereas 5Kc has 48. This makes 4Kc
558 dpavlin 24 emulation slower in general, because there are more TLB misses.

561 dpavlin 20 <p>The installation instructions above create a filesystem

980 dpavlin 2
981 dpavlin 10 Installing <a href="http://www.openbsd.org/pmax.html">OpenBSD/pmax</a> is
982     a bit harder than installing NetBSD/pmax. You should first read the <a
983 dpavlin 22 href="#netbsdpmaxinstall">section above</a> on how to install NetBSD/pmax,
984 dpavlin 2 before continuing here. If you have never installed OpenBSD on any
985 dpavlin 10 architecture, then you need a great deal of patience to do this. If, on
986     the other hand you are used to installing OpenBSD, then this should be no
987     problem for you.
988 dpavlin 2

994    
995     <p>
996 dpavlin 2 OpenBSD/pmax died at release 2.8 of OpenBSD, so you should be
997     aware of the fact that this will not give you an up-to-date OpenBSD
998     system.
999    
1000     <p>
1001     Following these instructions <i>might</i> work. If not, then use
1002     common sense and imagination to modify them as you see fit.
1003    
1004     <p>
1005     <ol>
1006     <li>Create an empty harddisk image, which will be the root disk
1007     that OpenBSD installs itself onto:<pre>
1008 dpavlin 12 <b>dd if=/dev/zero of=obsd_pmax.img bs=1 count=512 seek=900000000</b>
1009 dpavlin 2
1010     </pre>
1011     <li>Download the entire pmax directory from the ftp server: (approx. 99 MB)<pre>
1012 dpavlin 12 <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>

1021     </pre></td></tr></table>
1022 dpavlin 2 <li>You now need to make an ISO image of the entire directory you downloaded.
1023 dpavlin 10 (I recommend using <tt>mkisofs</tt> for that purpose. If you don't
1024 dpavlin 6 already have <tt>mkisofs</tt> installed on your system, you need
1025 dpavlin 10 to install it in order to do this.)<pre>
1026 dpavlin 12 <b>mkisofs -o openbsd_pmax_2.8.iso ftp.se.openbsd.org/pub/OpenBSD/2.8/pmax</b>
1027 dpavlin 24 <b>rm -rf ftp.se.openbsd.org</b> <i>(this directory is not needed anymore)</i>
1028 dpavlin 2
1029     </pre>
1030     <li>Start the emulator with all three (!) disk images:<pre>
1031 dpavlin 24 <b>gxemul -e 3max -d obsd_pmax.img -d b:simpleroot28.fs -j bsd -d c:openbsd_pmax_2.8.iso</b>
1032 dpavlin 2
1033     </pre>
1034 dpavlin 12 (If you add <tt>-X</tt>, you will run with the graphical
1035 dpavlin 6 framebuffer. This is <i>REALLY</i> slow because the console has to
1036     scroll a lot during the install. I don't recommend it.)
1037 dpavlin 2 <p>
1038     <li>Go on with the installation as you would do if you were installing on a real machine.
1039     If you are not used to the OpenBSD installer, then this will most likely
1040     be a very uncomfortable experience. Some important things to keep in mind are:
1041     <ul>
1042     <li>rz0 is the rootdisk you wish to install onto.
1043     <li>rz1 is the simpleroot image.
1044     <li>rz2 is the CDROM containing the "install sets".
1045     <li>When asked for the "<b>root device?</b>", enter <b>rz1</b>.
1046     <li>At "<b>Enter pathname of shell or RETURN for sh:</b>", press enter.
1047     <li>At the # prompt, do the following:<pre>
1048 dpavlin 12 <b>fsck /dev/rz1a</b> (and mark the filesystem as clean)
1049     <b>mount /dev/rz1a /</b>
1050     <b>mount -t kernfs kern kern</b>
1051     <b>./install</b>
1052 dpavlin 2
1053     </pre>
1054     and proceed with the install. Good luck. :-)
1055     <li>Answer "<b>y</b>" when asked if you wish to configure the network.
1056     (See the section about installing NetBSD/pmax for suitable
1057     network settings.)
1058     <li>Install from "<b>c</b>" (cdrom), choose "<b>rz2</b>" as the cdrom device, and "<b>/</b>" as
1059     the directory containing the install sets.
1060     </ul>
1061     <p>
1062 dpavlin 10 <li>For some unknown reason, the install script does not set the root
1063     password! The first time you boot up OpenBSD after the install, you
1064     need to go into single user mode and run <b>passwd root</b> to set
1065     the root password, or you will not be able to log in at all!<pre>
1066 dpavlin 24 <b>gxemul -e 3max -d obsd_pmax.img -d 2c:openbsd_pmax_2.8.iso -j bsd -o '-s'</b>
1067 dpavlin 2 </pre>
1068     While you are at it, you might want to extract the X11 install sets
1069     as well, as the installer seems to ignore them too. (Perhaps due to a bug
1070     in the installer, perhaps because of the way I used mkisofs.)
1071     <p>
1072     Execute the following commands in the emulator:
1073 dpavlin 12 <p><table border="0"><tr><td><tt>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</tt></td><td><pre>
1074     <b>fsck /dev/rz0a

1077 dpavlin 2
1078 dpavlin 12 cd /; mount -t cd9660 /dev/rz2c /mnt; sh
1079     for a in /mnt/[xX]*; do tar zxvf $a; done
1080     ln -s /usr/X11R6/bin/Xcfbpmax /usr/X11R6/bin/X
1081     ln -s /dev/fb0 /dev/mouse
1082     echo /usr/X11R6/lib &gt;&gt; /etc/ld.so.conf
1083     ldconfig
1084 dpavlin 2
1085 dpavlin 12 sync
1086     halt</b>
1087     </pre></td></tr></table>
1088 dpavlin 2 </ol>
1089    
1090     <p>
1091     NOTE: It is also possible to install via ftp instead of using a CDROM image.
1092     This is not much less awkward, you still need the simpleroot filesystem
1093     image, and you still have to manually add the X11 install sets and set the
1094     root password, and so on.
1095    
1096     <p>
1097     Once you have completed the installation procedure, the following command
1098     will let you boot from the new rootdisk image:
1099     <pre>
1100 dpavlin 22 <b>gxemul -e 3max -X -o '-aN' -d obsd_pmax.img -j bsd</b>
1101 dpavlin 2 </pre>
1102    
1103     <p>
1104 dpavlin 6 (Normally, you would be asked about which root device to use (<tt>rz0</tt>),
1105     but using <b><tt>-o '-aN'</tt></b> supresses that.)
1106 dpavlin 2
1107     <p>
1108     When asked for which terminal type to use, when logging in as root,
1109 dpavlin 6 enter <b><tt>rcons</tt></b> if you are using the graphical framebuffer,
1110     <b><tt>vt100</tt></b> for text-mode.
1111     <br>Use <b><tt>startx</tt></b> to start X windows.

1211 dpavlin 4 <p>
1212     The following instructions should let you install Ultrix onto a disk image:
1213    
1214 dpavlin 2 <ol>
1215     <li>Create an empty harddisk image, which will be the root disk
1216     that Ultrix installs itself onto:<pre>
1217 dpavlin 12 <b>dd if=/dev/zero of=rootdisk.img bs=1024 count=1 seek=800000</b>
1218 dpavlin 2
1219     </pre>
1220 dpavlin 6 <li>Place your Ultrix installation media in your CDROM drive.
1221     (On FreeBSD and similar systems, it is called <tt>/dev/cd0c</tt>.
1222     Replace that with the name of your CDROM drive, or the name of a
1223     .iso image file.) Then, start the emulator like this:<pre>
1224 dpavlin 24 <b>gxemul -X -e 3max -d rootdisk.img -d bc:/dev/cd0c -j vmunix</b>
1225 dpavlin 2
1226     </pre>
1227     <li>Once the first stage of the installation is done (restoring the root
1228     filesystem), you need to restart the emulator, booting from the
1229     new rootdisk, to continue the installation process.
1230 dpavlin 6 This is done by removing the bootflag ('<tt>b</tt>') from the second
1231 dpavlin 2 diskimage argument:<pre>
1232 dpavlin 24 <b>gxemul -X -e 3max -d rootdisk.img -d c:/dev/cd0c -j vmunix</b>

1236    
1237     <p>
1238     When the installation is completed, the following command should start
1239     Ultrix from the harddisk image:<pre>
1240 dpavlin 24 <b>gxemul -X -e 3max -j vmunix -d rootdisk.img</b>
1241 dpavlin 2 </pre>
1242    
1243 dpavlin 24 <p>If you have a very fast host machine, you might experience a weird
1244 dpavlin 10 timer related bug, which makes it impossible to logon to the system. It is
1245     triggered when the emulation goes faster than any real DECstation machine
1246     was capable of running. A temporary workaround is to add
1247     <b><tt>-I33000000</tt></b> to fix the emulated clock speed to 33 million
1248     instructions per emulated second. (When using <tt><b>-CR4400</b></tt>,
1249     <b><tt>-I16000000</tt></b> should be used instead.)
1250 dpavlin 2
1251     <p>
1252 dpavlin 6 You can experiment with adding <b><tt>-Z2</tt></b> (for emulating a
1253     dual-headed workstation) or even <b><tt>-Z3</tt></b> (tripple-headed), and
1254     also the <b><tt>-Y2</tt></b> option for scaling down the framebuffer
1255     windows by a factor 2x2.
1256     There is also a <b><tt>-z</tt></b> option for supplying names of X11
1257     displays to use. The following example starts Ultrix on an emulated
1258     tripple-headed workstation, on three different displays (<tt>remote1:0.0</tt>,
1259     <tt>localhost:0.0</tt>, and <tt>remote2:0.0</tt>), using no scaledown:<pre>

1287     A note for the historically interested: OSF/1 for MIPS was quite similar
1288     to Ultrix, so that is possible to run as well. If you are unsuccessful

1290     install it on your real machine onto a real SCSI disk, and then copy the

1365 dpavlin 10 <h3>Debian GNU/Linux for DECstation:</h3>
1366 dpavlin 2
1367 dpavlin 22 It is possible to run Debian GNU/Linux for DECstation in the emulator,
1368     on an emulated 5000/200 ("3max"). Although the Debian project has released
1369     install ramdisk kernels for this purpose, these do not always work:
1370     <ul>
1371 dpavlin 24 <li>Serial console output doesn't work too well in GXemul. Linux
1372     oopses randomly, which may be due to bugs in GXemul, but may
1373 dpavlin 22 also be due to bugs in the serial controller code in Linux.
1374     (The speed at which serial interrupts are generated can be
1375     lowered with the <tt>-U</tt> command line option, but it only
1376     reduces the risk, it doesn't take away the oopses completely.)
1377     <li>Old install kernels supported the graphical framebuffer on the
1378     3max, but not the keyboard.
1379     <li>For quite some time, the MIPS linux cvs tree had support for the
1380     keyboard, but it did <i>not</i> include Debian's patches for
1381     networking. (Perhaps this has been fixed now, I don't know.)
1382     </ul>
1383 dpavlin 10
1384 dpavlin 22 <p>David Muse has made available a precompiled install kernel which

1810     It is (almost) possible to install and run OpenBSD/arc on an emulated Acer

1812    
1813     <p><font color="#e00000">Earlier, I had this guest OS listed as

1817    
1818     <p>
1819     <ul>
1820     <li>The last OpenBSD/arc release was 2.3. This means that it is very
1821     old, it would not give a fair picture of what OpenBSD is (if you
1822     are just looking to find out what it is like), and it is not
1823     worth experimenting with it. See
1824     <a href="http://www.openbsd.org/arc.html">http://www.openbsd.org/arc.html</a>
1825     for more information.
1826     <li>OpenBSD/arc was (if I understood things correctly) never really
1827     stable, even on real hardare. Problems with too small an interrupt
1828     stack. Bugs are triggered in the emulator that have to do with
1829     issues such as this.

1837     <font color="#e00000">Currently, I don't test for every release whether
1838     or not OpenBSD/arc can be installed. Releases prior to 0.3.7
1839     (but probably <i>not</i> 0.3.7) should work. Anyway, here are the
1840     old installation instructions:</font>
1841    
1842     <p>To install OpenBSD/arc onto an emulated harddisk image, follow these
1843     instructions:
1844    
1845     <p>
1846     <ol>
1847     <li>Create an empty harddisk image, which will be the root disk
1848     that OpenBSD installs itself onto:<pre>
1849     <b>dd if=/dev/zero of=obsd_arc.img bs=1024 count=1 seek=700000</b>
1850    
1851     </pre>
1852     <li>Download the entire arc directory from the ftp server: (approx. 75 MB)<pre>
1853     <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>
1854    
1855     </pre>
1856    
1857     <li>You now need to make an ISO image of the entire directory you downloaded.
1858     (I recommend using <tt>mkisofs</tt> for that purpose. If you don't
1859     already have <tt>mkisofs</tt> installed on your system, you need
1860     to install it in order to do this.)<pre>
1861     <b>mkisofs -o openbsd_arc_2.3.iso ftp.se.openbsd.org/pub/OpenBSD/</b>
1862    
1863     </pre>
1864     <li>Start the emulator using this command line:<pre>
1865 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>
1866 dpavlin 22
1867     </pre>
1868     and proceed like you would do if you were installing OpenBSD
1869     on a real Acer PICA-61. (Answer 'no' when asked if you want to
1870     configure networking, and then install from CD-ROM.)
1871     </ol>
1872    
1873     <p>
1874     Once the install has finished, the following command should let you
1875     boot from the harddisk image:
1876     <p>
1877     <pre>
1878     <b>gxemul -X -e pica -d obsd_arc.img ftp.se.openbsd.org/pub/OpenBSD/2.3/arc/bsd</b>
1879    
1880     </pre>
1881    
1882     The system is very sensitive to (I think) kernel stack overflow, so it
1883     crashes easily. If I remember correctly from mailing lists, this also
1884     happened on real hardware.

2020     <h3>NetBSD/macppc:</h3>
2021    
2022     It is <font color="#ff0000"><b>ALMOST</b></font> possible to install and run
2023     <a href="http://www.netbsd.org/Ports/macppc/">NetBSD/macppc</a> in GXemul
2024     on an emulated generic PowerPC machine. No specific Machintosh model
2025     is emulated, but it is enough to for NetBSD to recognize it.
2026    
2027     <p>To install NetBSD/macppc onto a disk image, follow these instructions:
2028    
2029     <p>
2030     <ol start="1">
2031     <li>Create an empty harddisk image, which will be the root disk
2032     that you will install NetBSD/macppc onto:<pre>
2033     <b>dd if=/dev/zero of=nbsd_macppc.img bs=1024 count=1 seek=2000000</b>
2034    
2035     </pre>
2036     <li>Download the NetBSD/macppc 3.0 ISO image and a generic kernel:<pre>
2037     <a href="ftp://ftp.netbsd.org/pub/NetBSD/iso/3.0/macppccd-3.0.iso">ftp://ftp.netbsd.org/pub/NetBSD/iso/3.0/macppccd-3.0.iso</a>
2038     <a href="ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-3.0/macppc/binary/kernel/">ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-3.0/macppc/binary/kernel</a>/<a href="ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-3.0/macppc/binary/kernel/netbsd-GENERIC.MP.gz">netbsd-GENERIC.MP.gz</a>
2039    
2040     </pre>
2041     <p>
2042     <li>Start the installation like this:<pre>
2043     <b>gxemul -x -e g4 -d nbsd_macppc.img -d b:macppccd-3.0.iso -j macppc/binary/kernel/netbsd-INSTALL.gz</b>
2044    
2045     </pre>
2046     </ol>
2047    
2048     <p>If everything worked, NetBSD/macppc should now be installed on the disk image.
2049    
2050     <p><font color="#ff0000"><b>2006-02-26:</b></font> That's it. The installation
2051     succeeds, but it is not possible to start from the newly installed disk.
2052     /sbin/init dies, so the following command doesn't really work yet:
2053    
2054     <p>Use the following command line to boot the emulated machine:<pre>
2055     <b>gxemul -x -e g4 -d nbsd_macppc.img netbsd-GENERIC.MP.gz</b>
2056    
2057     </pre>
