CONFIDENTIAL COMPAQ Computer Corp. Larry Kunkel 07/13/06 Microcode Update ROMPAQ for systems using the 786C Family System ROM, revision 1.10 I. Reason for release: - Intel released updated production level microcode for the following processors: PROCESSOR CPUID PATCHID STEP TYPE ~~~~~~~~~ ~~~~~ ~~~~~~~ ~~~~ ~~~ Prescott F34 17 (D-0) Production update Prescott F41 17 (E-0) Production update Prescott F43 05 (N-0) Production Prescott F49 03 (G-1) Production Prescott F4A 03 (R-0) Production CedarMills F64 04 (C-1) Production CedarMills F65 07 (D-0) Production II. Release Document Details DESTINATION: Web, Factory Operating System: Independent Products: Grantsdale 786Cx ROM Family Notes: - This ROMPAQ operates in the same manor as the System ROM ROMPAQ, with the exception that the microcode ROMPAQ does not make a backup of the existing microcode on the system. - The Microcode Update ROMPAQ will only update the processor microcode, stored in the System BIOS, if the processor configuration requires it and the utility has the appropriate microcode. The two reasons that the microcode could need to be updated is when a new processor was installed in the system or the Microcode Update ROMPAQ contains a later version of the microcode for the currently installed processor. The correct operation of this utility is the identification of the system processor, then update the System BIOS microcode if necessary, and successful completion . If the ROMPAQ determines that the System BIOS microcode does not require updating or if the microcode versions contained in the ROMPAQ are not applicable to the system processor, the utility will complete successfully. The only reasons that the Microcode Update ROMPAQ would indicate an error is if a failure occurred while the System BIOS microcode was being updated or this version of the Microcode Update ROMPAQ in not supported on the system.
