PREMIUM SE 4/33 AND MAYNARD INTERNAL TAPE ADAPTER
PROBLEM: When using a Maynard (2000 DAT) Tape Backup with a 16-bit
internal Maynard SCSI adapter the system hangs.
CAUSE: The problem is caused by the Maynard SCSI controller cards
(part number 08-9-6010000 revision 3) that uses an AMD 33C93
chip at location U12. This chip generates noise which results
in an un-requested interrupt causing a system hang.
Maynard controllers shipping with a WD 33C93A chip at location
U12 do not have this problem.
AFFECTED
SYSTEMS: Premium SE and Premium TE systems with EISA motherboards (part
number 202377-00X).
SOLUTION: Contact Maynard Technical Support at 800-227-6296 for further
information and resolution.
