DESCRIPTION

When installing OS/2 Warp on a system with a CD-ROM drive connected to 
a Buslogic SCSI adapter (ISA AND PCI), a red screen appears when the 
system attempts to access the CD.

When attempting a Selective Install to add support for a CD-ROM drive 
when OS/2 Warp was installed without the CD-ROM drive, a SYS1201 error 
occurs, and the OS2DASD.DMD driver is not loaded when you restart the 
system.

The CD-ROM drive, and any other drives correctly attached to the 
Buslogic SCSI adapter, are usable in DOS or Windows.

If the Buslogic adapter and all the drives are transferred to another 
system, they all, including the CD-ROM drive, work correctly in OS/2.

RESOLUTION

Obtain and install the OS/2 Warp Fullpack version of the BTSCSI.ADD 
device driver.

Certain systems seem to present a timing discrepancy to a broad range 
of Buslogic ISA and PCI SCSI adapters. This is resolved by using 
BTSCSI.ADD. Currently, there is no definitive list of OEM systems or 
Buslogic-adapter combinations that experience the problem. It might be 
possible that only some Pentium systems with specific motherboards and 
BIOS revisions experience the problem.

It is reasonable to expect systems on the Compatibility List to work 
without experiencing this problem.
