In June I described a way to install OpenBSD 3.5 on a Soekris Net4801 small form factor system. I followed a similar method today with OpenBSD 3.6, installing from floppy to 2.5 inch HDD on one laptop and then moving the HDD to the Soekris.
I had two problems. The first involved not being able to use dd to write the OpenBSD floppy image to the floppy drive. I used this syntax:
orr:/root# dd if=floppyC36.fs of=/dev/fd0
At one point I got errors from dd. Later I saw these error messages from the kernel:
fdc0: ready for input in output
...repeats...
fdc0: ready for input in output
fdc0: too many errors, not logging any more
I was able to use the same syntax on a FreeBSD 4.10 box to create the boot floppy. I booted with the OpenBSD boot floppy and installed OpenBSD 3.6 on the laptop. When I moved the laptop HDD to the Soekris, I got this error via serial console as OpenBSD tried to boot:
booting hd0a:?1;2c: open hd0a:?1;2c: No such file or directory
failed(2). will try /obsd
boot>
I tried a generic 'boot' command next:
boot> boot
booting hd0a:/obsd: open hd0a:/obsd: No such file or directory
failed(2). will try /bsd.old
No joy. Then I remembered OpenBSD usually sees HDDs as device wd, so I tried this:
boot> boot wd0a:/bsd
booting wd0a:/bsd: 4918204+859636 [52+230528+209187]=0x5ee0fc

Booting from drive wd0a worked. I pondered having to repeat this process the next time I booted the system. However, after a reboot, I did not have to pass any parameters to the boot loader:

This second boot shows OpenBSD apparently booting from hd0a, which failed the first time. I don't know why this worked. I didn't have this issue with 3.5. I intend to turn this Soekris system into a firewall. For full dmesg output, see my new entry at NYCBUG.org.
