SPARCClassic won't boot cdrom

[Mouse]

> Are SCSI ID numbers likely to be an issue?

No.  Possible, certainly, but I would not say likely.

> Which ones are most commonly used on SparcClassic?

Disk at 0, 1, 2, 3; tape at 4, 5; CD at 6; the Classic itself at 7.

Those are what SunOS used, unless you reconfigured your kernel, and my
wild guess is that they're still the commonest, though modern systems
normally classify devices based on what they are rather than what ID
they're at.  (I don't know which camp post-SunOS versions of Solaris
fall into, though I would hope it's the one I called `modern'.)
