Initial test versions of a NetBSD/sparc binaries install are available
at
ftp.iastate.edu:/pub/netbsd/NetBSD-current/binaries/sparc
sun-lamp.cs.berkeley.edu:pub/NetBSD/arch/sparc
ftp.wonderland.org:NetBSD/arch/sparc [UK]
ftp.informatik.tu-muenchen.de:\
/pub/comp/os/bsd/NetBSD/NetBSD-current/binaries/sparc
and many other NetBSD mirror sites. Some mirror sites may take a day
or two to catch up.
The NetBSD/sparc port runs on sun4c class machines, ie. the
SS 1, 1+, 2, IPC, IPX, SLC, and ELC. it does not run on the
server-series machines, or the SS10-series machines.
The ftp directory contains a number of very large .tar.gz files in there,
as well as this document and a helper install script.
NOTE: THESE INSTRUCTIONS MAY CHANGE WITH EACH SNAPSHOT.
Until there are better instructions written, here's a rough idea:
1. format and partition the disk using sunos. yup, NetBSD/sparc uses
sunos disk labels. i am running a quantum 105 with these partition
sizes:
a: 28140 0 4.2BSD 1024 8192 16 # (Cyl. 0 - 133)
b: 16170 28140 unused 0 0 # (Cyl. 134 - 210)
c: 204540 0 unused 0 0 # (Cyl. 0 - 973)
g: 160230 44310 4.2BSD 1024 8192 16 # (Cyl. 211 - 973)
Filesystem 512-blocks Used Avail Capacity Mounted on
/dev/sd0a 26090 18846 4634 80% /
/dev/sd0g 149444 131496 3002 98% /usr
amd:43 0 0 0 100% /home
gecko:/usr/src 1549722 851783 542966 61% /usr/src
komodo:/usr/local 269346 243428 -1016 100% /usr/local
newt:/newt.usera 1128328 836910 178584 82% /tmp_mnt/newt/newt.usera
2. newfs it using sunos. yup, the filesystem format is identical.
UFS hasn't changed much over the years. (If you can, there is
a performance benefit from newfs'ing using NetBSD.)
If you newfs using the NetBSD newfs command, be sure to use -O
to specify the `4.3BSD filesystem format' for your / partition,
otherwise you will not be able to boot.
3. put a SunOS /boot program in the root partition, and use
"installboot" to cause it to work. the "installboot" man page
says to do something like this: say you are running SunOS, and
the drive you are installing NetBSD/sparc on is currently at
/dev/sd1. You have made the filesystems on that drive already.
# mount /dev/sd1a /mnt
# cp /boot /mnt/boot
# cd /usr/mdec
# ./installboot -vlt /mnt/boot bootsd /dev/rsd1a
4. extract the provided *.tar.gz files and dev.cpio.gz onto the disk.
the file "install.sh" will help you do this.
(the file dev.tar.gz is included, but is of limited use because
SunOS tar is not capable of extracting device nodes from tar
archives.)
mount your partition(s) in a proper tree starting at /mnt.
In the same directory as your *.tar.gz and *.cpio.gz files are, run
"./install.sh". (Now you may cut the head off the chicken and
spray the blood over your walls and ceiling.)
If you have done anything weird with partitions, take this moment
to ensure that etc/fstab is corrent for your disk layout.
5. the install script puts both the standard kernels in /mnt, and
links netbsd to netbsd-sd0. the filesystem images do NOT contain
these kernels. The same /etc/fstab file will work with either kernel.
the kernel "netbsd-sd0" expects your root drive to be at the standard
sunos sd0/scsi-id#3 location. "netbsd-sd1" maps scsi-id#1 to be sd0.
6. your rom may need some setup. make sure you boot from `new command mode'.
If your machine comes up and gives you a `>' prompt instead of `ok', type:
>n
ok setenv sunmon-compat? false
ok
this is needed because netbsd cannot handle the old-mode yet,
and will firework on you.
you cannot use the security modes of the sparc rom. sorry, same
problem as above.
ok setenv security-mode none
7. if needed, swap your scsi id's. now try a reboot. initially I'd
suggest you boot "-bs", then try multiuser after that. if you boot
single-user the netbsd incantation for making root read-write
is "mount -u /dev/sd0a /". alternatively, the command reboot is
found in /sbin.
8. to boot from netbsd by default, tell something like this to your
rom.
>n
ok setenv boot-from sd(0,0,0)netbsd
ok
please let me know of any errors in these instructions or in the
archives. if so i'll correct them.
good luck.
