 I'm confused a bit by this. You say that this CD-Rom drive
isn't the original one to the u10 and came from an older
machine, but the part number that you mention is for a 32x
ATAPI drive that is shipped with u5s and u10s originally.
 Can you clarify this somewhat?

 Did you try to boot the CD on any other machines? As
pointed out already, there is a difference between
booting to a CD versus just being able to read it on
a running system.

 Nope, Sun systems can boot to non-SCSI cdroms (hdds too).

 Can you write down the full physical path from doing the
following command? (Assuming that c0t2d0 is output from
the u10 and not a different machine that you used to
read the CD) Showing us the df -k output which refers
to the CD-Rom drive wouldn't hurt, either.

 # ls -la /dev/dsk/c0t2d0

 Also can you show us the output of the following two
commands (to be executed from the OpenBoot Prom)?

 ok show-devs
 ok devalias

 More than likely you just need to create a proper
'cdrom' alias for your OBP environment.
