NetBSD/pmax:
-- +
NetBSD/pmax was the +first guest OS that could be +installed +onto a disk image in GXemul. The device emulation of the DECstation +5000/200 is reasonably complete; it should be enough to emulate a +networked X-windows-capable workstation. + +
NetBSD/pmax 1.6.2 works perfectly with X out-of-the-box. Unfortunately, +newer NetBSD releases have changed slightly, and X does not work straight +away with NetBSD 2.x and 3.x. It seems that this has to do with NetBSD +switching console system to "WSCONS" somewhere between 1.6.2 and 2.0. + +
What this means is that if you want to use emulated X11, then you need +to run NetBSD 1.6.2. At the time of writing this, 4.0_BETA snapshots work +fine too, but 4.0 isn't released yet. If you feel that you only need +serial-console emulation, then choose 3.1. + +

NetBSD/evbarm:

+
+It is tricky to install, because there is (as far as I know) no INSTALL +kernel. One way to install the NetBSD/evbarm distribution onto a disk +image is to install the files using another (emulated) machine. + +
The following instructions will let you install NetBSD/evbarm onto a disk +image, from an emulated CATS machine: + +
+
-
+
- Install NetBSD/cats 3.1 according to instructions
+ further up on this page.
+
+
- Create an empty harddisk image, which will be the disk image
+ that you will install NetBSD onto:
+ dd if=/dev/zero of=nbsd_iq80321.img bs=1024 count=1 seek=999000 + +

++
- The first step is to copy the distribution .tgz files onto the CATS
+ machine's harddisk. Start the CATS machine like this:
+ gxemul -XEcats -d nbsd_cats.img -d evbarmcd.iso netbsd.aout-GENERIC.gz + +
and execute the following commands as root: +
++mount /dev/cd0a /mnt; cd /root; cp /mnt/evbarm/binary/sets/[bcegmt]* . +sync; halt +
+
- Now let's extract the files onto the IQ80321's disk image. Start the
+ CATS machine again, with the following command line:
+ gxemul -XEcats -d nbsd_cats.img -d nbsd_iq80321.img netbsd.aout-GENERIC.gz + +
and execute the following commands as root: +
++disklabel -I -i wd1 + (enter suitable commands, e.g. a, 4.2BSD, 1c, 750M, b, + swap, a, 200M, P, W, y, Q) +newfs /dev/wd1a; mount /dev/wd1a /mnt; cd /mnt; sh +for a in /root/[bcegmt]*.tgz; do echo $a; tar zxfp $a; done +exit +cd dev; sh ./MAKEDEV all; cd ../etc +echo rc_configured=YES >> rc.conf +echo "/dev/wd0a / ffs rw 1 1" > fstab +echo "/dev/wd0b none swap sw 0 0" >> fstab +cd /; umount /mnt; sync; halt +

++
- Start the emulated DECstation machine like this:

+ - At the Terminal type? [rcons] prompt, type CTRL-B
+to simulate a CTRL-C sent to NetBSD/pmax. Then execute the following commands:

NetBSD/netwinder is now installed on the disk image. The following command +line can be used to start NetBSD/netwinder:

+ +This will result in a 1024x768 framebuffer. Add -Y2 to the +command line if you want to scale it down to 512x384. + +
Note: The installation instructions above create a filesystem +without a disklabel, so there is only one ffs partition and no +swap. You will need to enter the following things when booting with the +generic kernel:
+ root device (default wd0a): wd0c + dump device (default wd0b): (just press enter) + file system (default generic): (just press enter) + init path (default /sbin/init): (just press enter) +
+ +Known bugs/problems: + +
-
+
- There is a long delay when starting up NetBSD/netwinder + (several seconds even on a very fast host machine), + so you need to be patient. +
- There is a minor bug in the keyboard device, so you need to + press a key (any key) before typing wd0c. +
- When halting/rebooting NetBSD/netwinder, the emulator + prints a message saying something about an internal + error. This doesn't matter; ignore the message. +

-
+
- Put a "Windows NT 4.0 for MIPS" CDROM (or similar) into

+ usually called /dev/cd0c or similar. Change
+ that to whatever the CDROM is called on your system,
+ or the name of a raw .iso image. I have tried this
+ with the Swedish version, but it might work with
+ other versions too.)

+ dd if=/dev/zero of=obsd_landisk.img bs=1024 count=1 seek=900000 +
+ - Download the entire landisk directory from the ftp server:
+ wget -np -l 0 -r ftp://ftp.se.openbsd.org/pub/OpenBSD/snapshots/landisk/ + cp ftp.se.openbsd.org/pub/OpenBSD/snapshots/landisk/bsd . + cp ftp.se.openbsd.org/pub/OpenBSD/snapshots/landisk/bsd.rd . +
+ (Replace ftp.se.openbsd.org with a server closer to you, for + increased download speed.) ++
- You now need to make an ISO image of the entire directory you downloaded.
+ (I recommend using mkisofs for that purpose. If you don't
+ already have mkisofs installed on your system, you need
+ to install it in order to do this.)
+ mkisofs -allow-lowercase -o openbsd_landisk_snapshot.iso ftp.se.openbsd.org/pub/OpenBSD/ + rm -rf ftp.se.openbsd.org (this directory is not needed anymore) + +
+ - Start the emulator using this command line:
+ gxemul -x -Elandisk -d obsd_landisk.img -d d:openbsd_landisk_snapshot.iso bsd.rd + +
+ and proceed like you would do if you were installing OpenBSD + on a real landisk. The following hints are useful to get you + through the installation: +-
+
- Terminal type = xterm +
- root disk = wd0 (the disk to install onto) +
- Use the entire disk for OpenBSD = yes +
- Create one big root partition (a) and a small swap partition (b). c is the entire disk. +
- Do not configure the network. +
- Location of sets = disk +
- Is the disk partition already mounted = no +
- Disk containing the install media = wd1 +
- Pathname to the sets = snapshot/landisk +
Once the install has finished, the following command should let you +boot from the disk image: + +
+ gxemul -x -E landisk -d obsd_landisk.img bsd + +
- Download the OpenBSD/sgi GENERIC and RAMDISK kernels:
- Start the DECstation emulation again, and download the - NetBSD/sgimips distribution sets:
- Create an empty harddisk image, which will be the root disk
that NetBSD installs itself onto:
- Download a NetBSD pmax INSTALL kernel:
