So what's stopping it from using wide protocol?  Have you checked all 
the jumpers on the CD-ROM?

Remember that if you have multiple SCSI-HBAs in the system that each has 
it's own BUS and EACH BUS can have a SCSI-ID0/1/2/3/4/5/6/8/9 ....... 
they can be duplicated - you could have four devices with SCSI-ID=0, one 
on each of four HBAs fitted  for example.  Have you ever had 15 devices 
attached to a single HBA?

Hi Don,
I noticed in one of Felix's replies that he stated that search order for 
first active boot device is from LOW to HIGH not as you stated above. I 
aleays though that primarily SCSI-IDs 8-15 were intended for external 
devices.  After SCSI-ID=7, ID=6 is next highest priority, as used by 
second HBA for example.

Another thought is that PARITY checking must be the same on all devices 
on the bus.
