IBM PC730/PC750 - Failures after installing MicroChannel bus
Applicable to: World-Wide
Symptom:
A limited number of early production PC 700 ISA/PCI Series systems 6875 and 6885 may exhibit one or more of the following symptoms after installing the MicroChannel SelectaBus Option.
1. Intermittent system hangs.
2. Errors loading or using Crystal Business Audio Drivers.
3. Errors loading or using MicroChannel adapter device drivers.
4. MicroChannel adapter configuration errors.
Problem Isolation Aids:
The symptoms stated above may be related to the level of system board installed in the PC 700 6885 or 6875. Early ship levels of this system which are typically used for Marketing demonstrators, loaners, or sold to end users, were not released with support for the SelectaBus option.
The SelectaBus option changes the bus type from ISA/PCI to MicroChannel by replacing the existing riser card with a MicroChannel version and updating the Flash BIOS. System boards with the following manufacturing part numbers on the barcode label attached to system board FRU P/N88G4270 are affected:-
P/N11H5588
P/N11H5589
P/N11H5590
P/N11H5611
P/N11H5618
P/N12H1970
P/N39H8258
Fix:
If the system contains a system board with one of the affected part numbers, installation of the SelectaBus option is not supported. Do not replace the system board. The customer should be directed back to their point of sale.
