What is the specific error you get about Solaris 10 and in what context? Unless you don't have enough memory, there's no reason that an Ultra 10 can't run Solaris 10.
If you reset the machine, can you do a probe-ide and see the drive? Can you boot to single-user from the CD and run format->analyze on the hard drive?

No Ultra 10 has that configuration. Perhaps you meant you had an Ultra 1?
All Ultra 10s have an UltraSPARC IIi of at least 300MHz and are supported by Solaris 10 (provided you have enough RAM).

And no Ultra 1 has an ATA device... I'm not sure what kind of machine you have.
What is the context for this timeout? Is it immediately after typing 'boot cdrom' and before anything else appears? If so, I'd assume you either had a bad CD drive, a bad media disk, or a bad cable. But I don't know that you'd see 'c0 d0' (or anything like that) until the OS started booting.
Maybe it's complaining about the internal hard drive. If you can boot from the cd, you can run an analysis on the internal hard drive.

Daren-
First, thanks for the help thus far. You are correct, the machine is an Ultra 1 with 512Mb of RAM and two 4Gig hard drives. The processor is 168MHz. I'm trying to load Solaris 8 on it. I get all the way through the drive selection process where it tries to write to the hard drives and then it fails with WARNING: ata_timeout c0 d0

So the CD boot process is working. Sounds to me like the hard drive has a problem. Are you sure the drive is working?
If you boot single-user from CD ('boot cdrom -s'), you can run 'format', select a disk, then enter 'analyze'. Does a read analysis on the disk run for any period of time?
Disk failure is the most likely problem from the description you've posted so far.
