I tried what you suggested and it worked ... sort of. Situation: I removed the power cord from scsi disk one and booted up and the bootmgr successfully saw both disks: IDE and (normally the second) scsi disk. So I plugged scsi disk 1 back in (power cord) , rebooted the machine and noticed that the bootmgr only displayed one function choice again (F1: dos). Just for grins I decided to choose F5 and the bootmgr showed me the second disk boot option (F1: freebsd). So I decided to swap the scsi disk's device ids (so scsi disk 1 became scsi disk 2 and vice versa) and reinstalled FreeBSD. Now the bootmgr stills displays only one option (F1: dos) but I can still access FreeBSD by choosing F5. However, when freeBSD boots it gets to the point where it attempts to mount root and it says: . . changing root device to sd1a PANIC: Unable to mount root. . . Well of course it can't mount root from sd1a as I did not install any mount points to that partition. What I did when installing: I went into the partition editor and picked sd0. I used the entire disk and set it bootable. I did nothing else with either the IDE disk or scsi disk 2 via the partition editor. I went to the partition label tool next and noticed that it only displayed my sd0 as available to label (which made sense to me since the other two disks I didn't identify as available). I divided the disk: / ....... 80M (swap) .. 80M /usr .... 652M Then I installed (committed) selecting the bootmgr (booteasy) option. Question: Why did the system want to use sd1a when I didn't create any partitions on that disk (scsi disk 2), or label? Do I have to somehow associate DOS as the owner of the other partitions on IDE disk and scsi disk 2, before I install?

My guess is that your BIOS only supports two harddisks, so you're not going to be able to boot off the third disk. Swap disks 2 & 3 and see if DOS still sees the DOS SCSI disk. > Question: Is there a simple way for me to tell the bootmgr > about this second bootable drive? The bootmanager asks the BIOS, AFAIK.
