It seems that wd1 intercepts >whatever incantation I use (sd1, hd1, etc.) This configuration isn't supported by the standard bootblocks. If the BIOS supports sd1, then you can boot from it after changing an 0 to a 1 in the bootblock source or binary. Then boot by typing hd(n,a)/kernel, where `n' is the BIOS number of the drive. `n' might be 3 for the above configuration. hd(n,a) now forces the FreeBSD unit to 0 so it only works for wd0 and sd0.
