Several IBM PS/2 Models have a unique SCSI hard drive controller that
may cause Seagate Backpack Software version 5.3.x to lock-up the
computer while the system is "searching" for a backup device. This
lock-up has occurred with several PS/2 models including models 77, 80,
90, and 9557. There is the potential for this problem to occur on other
PS/2 and NCR computer models as well. This problem can be fixed by
installing an updated driver within the Seagate Backup software. This
update can be downloaded from the Micro Solutions BBS or Website. The
filename to download is SB53PS2.EXE and can be found in the "Utilities
and Misc." section of the "Software Library".
