Anyone one else here having trouble with the ASUS P4C800-E Deluxe motherboard and the Microsoft SP2? Anyone hear about this - Intel P4 Prescott, Celeron D, or Extreme Edition processor
Some affected motherboards
Albatron PX865 PE Pro
Aopen AX4SG Max
Asus P4P800-E deluxe
Motherboards with one of these types of processor may need a BIOS update. One emergency measure is to either boot into safe mode or disable both L1 and L2 caches in the BIOS to get the machine to boot, then uninstall Service Pack 2, then wait for an updated BIOS or...
The cause appears to be that the machine's BIOS does not install a production level microcode update (a correction to a fault in the microprocessor's own microcode).
To check whether the BlOS is at the correct level download the Intel Processor Frequency ID utility from http://support.intel.com/support/processors/tools/frequencyid/. The microcode version is identified by this utility as "CPU Revision".
Family 15 (0xF), model 3, stepping 4 â€“ must have a microcode update signature of at least 8. Latest microcode update signature is E.
Family 15 (0xF), model 3, stepping 3 â€“ must have a microcode update signature of at least 7. Latest microcode update signature is B.
Family 15 (0xF), model 3, stepping 2 â€“ must have a microcode update signature of at least 7. Latest microcode update signature is A.
If the revision number is lower than that or zero, boot into Safe Mode. Rename the file:
to some other name like updateDISABLED.sys so that it does not load.
Reboot into normal mode. Install Service Pack 2 again, and the computer should now boot up completely.
Check your motherboard manufacturer's website often for updates to your BIOS, as this is only a temporary workaround.
