ECA 031 - 8580-111/311 + Busmaster

Compatibility with "wizard" and Busmaster adapters

PURPOSE:
To make available a current level system board for 8580 models 111 + 311 which are using the ps/2 wizard adapter or other Busmaster adapters.

NOTE: The IBM SCSI adapter with cache memory and SCSI adapter without cache memory are "Busmaster".

This ECA is not applicable to 8580 models 041 + 071.

PHYSICAL check:
Inspect the installed system board for a FRU part number. The FRU number is located near the lower rear corner of the system board and will be printed in white letters or on a white label. Removal of adapters may be necessary to locate the FRU part number.

This ECA is only applicable to 8580 models 111 and 311 which have FRU P/N 90X7390, or those model 111 + 311 systems where the installed system board FRU part number cannot be determined.

This ECA is not applicable to 8580 models 111 + 311 which have system board FRU P/N 33F8415 installed.
(FRU P/N 33F8415 was previously released with ECA:011).

DETAIL:
If 110 parity errors are experienced when using a Busmaster adapter card such as the IBM "wizard" adapter and the system board FRU part number is applicable for this ECA:, as described in the physical check, replace the system board with the currently available system board FRU.

If the system board FRU part number does not apply to this ECA:, as defined by the physical check, and problems are being experienced with a Busmaster adapter, use normal problem determination procedures for problem resolution.

Marketing literature refers to EC C00835 as being required on 8580 systems using the wizard adapter. This EC has been incorporated on all system boards except FRU P/N 90X7390, which was the initial system board for 8580 models 111 + 311.
