With `b' or with `b sd(0,6,2)' ?

Sounds like you're booting off the hard disk, but it was originally
configured with external disks as well, which are either missing or
have the wrong SCSI IDs. If you're going to wipe everything, don't
worry about this.

This is all just it booting into SunOS, but with important disks missing
(because they were originally external or suchlike).

esp0 is the first SCSI controller.

If you want to see if it's found all the devices, get it to the
`b for boot, ...' prompt, and type `n'. That will get you to an
`ok' prompt. Then type `probe-scsi-all', which will print out
a list of all the SCSI devices found.

Otherwise, do a `b sd(0,6,2)' from the `b for boot, ...' prompt,
as Bill suggested.
