So I've been searching for hours now, and it appears that short of
reading the C code, there's no documentation of the boot2 menu prompt.
Sure, it says drive:driver(unit,slice,part)
But no combination of those three that I can find actually works.
There's two LUNs:
drive 0: single 2TB slice
drive 1: 264GB, with root, swap, etc
How do I tell boot2 to find the loader on disk1?
1:da(1,a)
1:da(1,1,a)
1:da(0,1,a)
1:da(0,a)
0:da(1,a)
0:da(0,a)
...etc none of them work.

How do you determine this for a SCSI drive? And what is the difference between the drive number and the unit number anyway? That entire section is actually impossible to decipher except for the single drive IDE disk scenario which is documented there. -- Jo Rhett senior geek Silicon Valley Colocation

I think you need to specify the file to load: 1:da(1,a)/boot/loader -- Suleiman

Does it show any devices besides the raw disks? I had similar problem with ASUS Vintage-PE1 hardware. It never showed any devices to boot except two raw disks (I had GEOM Mirror setup). And I never found a way to work around this. -- VH -------------- next part -------------- A non-text attachment was scrubbed...
