Oh, it also means that the protected mode disk driver can't find the root device that the real mode BIOS boot blocks successfully loaded the kernel from. Typically, you can fix this by hacking the disklabel, which must be accessible from DOS. Unfortunately it doesn't report exactly why it can't mount root (partition ID, wrong disk if a second drive, unreadable disklabel, or disklabel absolute offsets don't refer to the untranslated location), so the above is just a "most likely" guess. Can you mount from floppy? What about trying various hd and wd and sd devices at the boot prompt? (did you install on a SCSI or wd drive, does tha machine have both types of controllers, is the BIOS enabled or disabled on the controller for the BSD disk, is it the first disk, etc.).
