- The SCSI tape drive I was using had the same problem. Try
- configuring it as lunit 2. It seems to work at 2 with one or
- two SCSI drives. I have not traced down why it will not work as
- unit 4, but I suspect it could be changed in the kernel configuration.
-
- I believe you are correct in that most other O/Ss expect it as unit 4.
- If Bill is reading this and it is possible to change in the configuration,
- maybe the first set of official patches will change this.

- I'm interested. Especially in the part that allows possible booting from
- a second disk. The partition booter I was using is not compatible with
- 386BSD.
