NetBSD/pmax 1.6.2 works perfectly with X out-of-the-box. Unfortunately, +newer NetBSD releases have changed slightly, and nowadays X does not +work straight away.

+
+
+ +- The last OpenBSD/arc release was 2.3. This means that it is very + old, it would not give a fair picture of what OpenBSD is (if you + are just looking to find out what it is like), and it is not + worth experimenting with it. See + http://www.openbsd.org/arc.html + for more information. +
- OpenBSD/arc was (if I understood things correctly) never really + stable, even on real hardare. Problems with too small an interrupt + stack. Bugs are triggered in the emulator that have to do with + issues such as this. +

+
+ +- Put a "Windows NT 4.0 for MIPS" CDROM (or similar) into + your CDROM drive. (On FreeBSD systems, it is + 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.) +
+
- Create an empty harddisk image, which will be the disk image + that you will install Windows NT onto:
+ $ dd if=/dev/zero of=winnt_test.img bs=1024 count=1 seek=999000 + ++- Run the ARC installer, to partition the disk image:
+ $ gxemul -X -e pica -d winnt_test.img -d bc6:/dev/cd0c -j MIPS\\ARCINST ++ Note that ARCINST almost works, but not quite. ++
- Run the SETUP program:
+ $ gxemul -X -e pica -d winnt_test.img -d bc6:/dev/cd0c -j MIPS\\SETUPLDR ++SETUPLDR manages to load some drivers from the cdrom, +but then it crashes because of incomplete emulation of some hardware devices. + + + + + + + + +
NetBSD/macppc:
+ +It is ALMOST possible to install and run +NetBSD/macppc in GXemul +on an emulated generic PowerPC machine. No specific Machintosh model +is emulated, but it is enough to for NetBSD to recognize it. + +To install NetBSD/macppc onto a disk image, follow these instructions: + +
+
+
+ +- Create an empty harddisk image, which will be the root disk + that you will install NetBSD/macppc onto:
+ dd if=/dev/zero of=nbsd_macppc.img bs=1024 count=1 seek=2000000 + ++- Download the NetBSD/macppc 3.0 ISO image and a generic kernel:
+ ftp://ftp.netbsd.org/pub/NetBSD/iso/3.0/macppccd-3.0.iso + ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-3.0/macppc/binary/kernel/netbsd-GENERIC.MP.gz + +++
- Start the installation like this:
+ gxemul -x -e g4 -d nbsd_macppc.img -d b:macppccd-3.0.iso -j macppc/binary/kernel/netbsd-INSTALL.gz + ++If everything worked, NetBSD/macppc should now be installed on the disk image. + +
2006-02-26: That's it. The installation +succeeds, but it is not possible to start from the newly installed disk. +/sbin/init dies, so the following command doesn't really work yet: + +
Use the following command line to boot the emulated machine:
+ gxemul -x -e g4 -d nbsd_macppc.img netbsd-GENERIC.MP.gz + ++ + + + + + + + + + + + +NetBSD/bebox:
+ +There is an old snapshot of +NetBSD/bebox +from 1998-11-19 available at NetBSD's ftp server. NetBSD/bebox +could theoretically run in GXemul. +IT DOES NOT WORK RIGHT NOW! + +The following instructions will let you install NetBSD/bebox onto a +disk image, using a NetBSD/prep kernel temporarily during the install: + +
+
+
+ +- Download a NetBSD/prep 2.1 install ramdisk kernel:
+ ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-2.1/prep/binary/kernel/netbsd-INSTALL.gz +++
- Create an empty harddisk image, which will be the disk image + that you will install NetBSD onto:
+ dd if=/dev/zero of=nbsd_bebox.img bs=1024 count=1 seek=999000 +++
- Download the NetBSD/bebox snapshot, and create a suitable .iso + image of the files: +
+
+
- Now let's extract the files onto the Bebox disk image. Start NetBSD/prep + with the following command line:
+ gxemul -x -e ibm6050 -d d:netbsd-bebox-19981119.iso -d nbsd_bebox.img netbsd-INSTALL.gz + +Choose (S) for Shell, and execute the following commands: ++
You should now be able to boot NetBSD/bebox using this command:
+ gxemul -X -E bebox -d nbsd_bebox.img netbsd ++ +When asked for the root device, enter wd0a. + +
IT DOES NOT WORK YET, there are +errors while uncompressing the tgz files, and the machine crashes when +trying to run /sbin/init. + + + + + +
