Sure it was detected. It was also disabled because we couldn't talk to it at Ultra speeds. The BIOS does not perform much if any I/O at Ultra speeds to CDROMs during boot, so it may not see this problem. > When I replace the 2940U by a 2940 I don't have those problem??? The 2940 doesn't run at Ultra speeds. Your drive may work just fine when you slow down the bus. Do you get similar results when you set the failing CDROM to 10MB/s in SCSI-Select? Your cabling or termination doesn't seem to be up to snuff for Ultra speeds to the failing drive. -- Justin
