IBM PC730/PC750 - Fails to boot after updating Flash BIOS
Applicable to: World-Wide
Symptom :
IBM PC 700 Series 6875, 6885, 6876 or 6886 systems may not function after exiting from a Flash BIOS update procedure when it is determined that the system already contains the same BIOS level as the Flash update diskette.
Problem Isolation Aids :
**** DO NOT ATTEMPT TO RECREATE THE FAILURE SYMPTOM ****
The failure occurs as a result of performing a flash update on a system containing the same level as the flash update diskette.
The system warns the user that "The Flash level currently installed on the system is the same as the flash update diskette." If the user selects option to discontinue the update when prompted "Do you want to continue Y/N?", the system will appear to function normally following the prompted Ctl+Alt+Del sequence, but will exhibit no video, no POST (Power On Self Test), and no beep code following a power off/on cycle.
Fix :
The system board must be replaced in the systems that have been affected by this problem.
To prevent this failure from reoccurring, perform the following step as a standard procedure PRIOR to installing a flash BIOS update:
1) Determine the flash BIOS level currently installed on the by accessing the Configuration Setup Utility by pressing F1 during the memory count. The fifth, sixth and seventh positions of the Flash BIOS Revision Level represents the code level; for example: N1JT84AUS is code level 84A.
Compare the flash BIOS Revision Level of the system to the flash BIOS update diskette or image. DO NOT install the BIOS update if the levels are the same.
An updated version of the Flash Update utility has been developed to prevent the symptom stated above from occurring. The new Flash Update utility, FLSHUPDT.EXE will be contained on the next revision of the PC 700 6875/6885 6876/6886 Flash Update diskettes (levels following N1JT84A ISA/PCI & N2JT47A Micro Channel).
If the FLSHUPDT.EXE on the flash update diskette is dated 7-20-96 or earlier and has a byte count of 66460, this update has the capability to cause the symptoms stated above.
