It could easily be an old enough drive that it wants good CD-R media (I have a spindle of Taiyo Yuden for that very purpose). Since the Ultra 5 uses IDE, you could put in another drive and see if that solves your problem.

You can also do a device scan at the boot prom ("help" will help you find the command) and scan to see what device address the CD-ROM has, but since it's IDE, I expect that the PROM would expect the CD to be the slave drive on the primary channel (assuming the Ultra 5 has only one channel, which I think is the case).

Hi, all.

It's a few years since I've posted to the list, and my last Sparc was an SS20.

've just taken delivery of a 'new' Ultra 5, but for the life of me
can't boot a CD.  The cd drive is an OEM model that was originally
sold with the Ultra 5 and I have no reason to suspect that it hasn't
been fitted since new.  I suspect that my 'cdrom' alias is pointing to
the wrong place, or my cd media is incompatible (cd-r).  Having read
several how-to's, I am still unable to fathom this one out.  Can
anyone lend me a helping hand?

Many thanks,

Chris.
