Thanks for all the responses. I got it:
This machine has SCSI hard drives and my other linux based ide - cdr
does not have SCSI disks. When I originally built this kernel, I
modularized everything to-do with the cdrom including ide support and
the generic SCSI stuff. On the one that cdr works, all ide stuff is
compiled into the kernel, so that it can boot from the ide hard drive.
So I added the ide support directly into the kernel and not as a
module. This worked. I just burn my first cdrom on the new drive.
cdrecord -scanbus:
scsibus0:
