Opps, 2 drives, both as IDE master, one on primary and one on secondary.
Also a CDROM as secondary slave. Also to make matters worse 2 SCSI drives.
The complete mapping is...
BIOS number FreeBSD name
0x80 wd0
0x81 wd2
0x82 da0
0x83 da1
For the moment I am not trying to do anything with the SCSI drives,
although da1 has a FreeBSD slice. Both wd0 and da0 re FAT32 Winblows.
New information...
I have been able to get the kernel into single user mode, where mount /
barfs about not being able to mount /dev/wd2s1a on / because the
filesystem is different. However an ls shows it _did_ get the right one,
it just thinks it's wrong. Also curiously the normal boot-time message
"changing root device to wd2s1a" doesn't appear. I can get this far using
2 methods...
Booting using 1:wd(1,a)/boot/loader
Then at the loader type
load kernel
set currdev=disk3s1a:
boot
With this both currdev and loaddev are initially set to disk2s1a:
Or boot using 1:wd(2,a)/boot/loader
Then at the loader type
set currdev=disk2s1a:
load kernel
set currdev=disk3s1a:
boot
With this both currdev and loaddev are initially set to disk3s1a: The
loader is also unable to access files (ls, source, help, load, etc) until
I set currdev to disk2s1a:
It seems that I need currdev=disk2s1a: so that the loader can load files,
and I need currdev=disk3s1a: so that the kernel will mount root. Two
conflicting requirements.
I'm off now to play now with rootdev and boot_askname.
Cheers.
