The thing is, BIOS doesn't number them differently, ata is always
first, then sata drives (there is no sata/pata in bios boot order, just
hd-0,1,2,3,4...), it is the OS renumbering the drives, so I imagine it
could be programmed or configured to do "the thing I expect" -- whether
that is right or not.
dkcsum: wd0 matched BIOS disk 81
dkcsum: wd1 matched BIOS disk 80
I think the only thing required is a "configuration" to make BIOS 0x80
always map to wd0.
biosboot(8), boot(8), disklabel(8), fdisk(8), init(8), boot_i386(8),
installboot(8) autoconf(4), biosboot(8), boot_config(8), config(8)
...but I don't see mention of "BIOS disk"...
