Hi guys, All my drive problems went away when I used a different IDE cable. Unfortunately, I only have one spare, non-pin-blocked IDE cable around, so I'm running just the hard drive for now. FreeBSD booted just fine from the IDE drive, though. When I round up another non-pin-blocked IDE cable I'm certain the CD-ROM and second hard drive will show up without problem. The IDE performance on this PC164 leaves much to be desired. I'm going to have to toss a SCSI card in this thing and just go SCSI.
