IBM has determined that some 9556 and 9557 486SLC3 Systems manufac-
tured and shipped prior to February 16, 1994 may fail to load large
software applications from diskettes.

The failures encountered may be system hangs, OS/2 system errors
(SYS0049, SYS3175, SYS0318) and Trap Errors 0004,0006, 0008 or 000D.

If any of the above errors are encountered and the system board has a
FRU P/N of 71G3599 or 65G8615, replace the system board with new FRU
P/N 65G9714. If the system board FRU P/N is 65G9714 further problem
determination should be utilized to isolate the failing FRU. This
system board is not affected by this problem and is not to be replaced
under this ECA.

NOTE:  IBM recommends that all affected system boards be replaced
before a customer experiences a potential problem.

All orders for FRU P/N 71G3599 and 65G8615 will be substituted to FRU
P/N 65G9714.
