Ultra AXmp SCSI CDROM

I have an Ultra AXmp with a SCSI CDROM drive. The drive has performed flawlessly to install both Solaris 9 and a Debian distro of linux. While attempting to load another distro of linux I believe I chose the wrong driver and the cdrom drive has stopped working. probe-scsi-all detects the drive knows where it is and what it is but, will not boot. I've reloaded the OpenBoot prom and that had no effect. Any ideas?

Thanks,
Michael
