Installing NetBSD/cobalt in GXemul:
+
+NetBSD/cobalt is tricky
+to install, because the Cobalt machines were designed for Linux, and not
+very flexible. There is no INSTALL kernel for NetBSD/cobalt. One way to
+install the NetBSD/cobalt distribution onto a disk image is to do it from
+another (emulated) machine.
+
+
+
+
+
+
+The following instructions will let you install NetBSD/cobalt onto a disk
+image, from an emulated DECstation 3MAX machine:
+
+
+
+ - Create an empty harddisk image, which will be the disk image
+ that you will install NetBSD/cobalt onto:
+ $ dd if=/dev/zero of=nbsd_cobalt.img bs=1024 count=1 seek=1999000
+
+
+ - Install NetBSD/pmax 2.0 according to instructions further up
+ on this page.
+
+
- Download the generic kernel for Cobalt (and gunzip it) and
+ the 2.0 ISO image:
+ ftp://ftp.se.netbsd.org/pub/NetBSD/NetBSD-2.0/cobalt/binary/kernel/netbsd-GENERIC.gz
+ ftp://ftp.se.netbsd.org/pub/NetBSD/iso/2.0/cobaltcd.iso
+
+
(You may want to choose a mirror closer to you, if .se is slow.)
+
+
- Start NetBSD/pmax like this:
+ $ gxemul -b -Edec -e3max -d nbsd_pmax.img -d cobaltcd.iso -d nbsd_cobalt.img
+
+
+ - Log in as root (on the emulated 3MAX machine), and execute the
+ following commands: (adjust according to taste)
+ # newfs /dev/sd1c
+ # mount /dev/cd0c /mnt
+ # mkdir /mnt2; mount /dev/sd1c /mnt2
+ # cd /mnt2; sh
+ # for a in /mnt/cobalt/binary/sets/*.tgz; do echo $a; tar zxfp $a; done
+ # exit
+ # cd dev; sh ./MAKEDEV all; cd ../etc
+ # echo rc_configured=YES >> rc.conf
+ # echo "/dev/wd0d / ffs rw 1 1" > fstab
+ # cd /; umount /mnt; umount /mnt2; halt
+
+
+
+
+You should now be able to boot NetBSD/cobalt like this:
+ $ gxemul -b -M128 -E cobalt -d nbsd_cobalt.img netbsd-GENERIC
+
+
+Note that 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): wd0d
+ dump device (default wd0b): none
+ file system (default generic): ffs
+
+
+
+
