    I upgraded my CPU from P4 531 to P4 641 and now all I get is "Alert!Incompatible processor detected" during POST, I press F1 to continue, everything is OK, OS can identify P4 641 CPU.

    Error Message:"Alert! incompatible processor detected
    Strike the F1 to continue,F2 to run the setup utility "

    I did the following:
    1. Loaded the latest ver A11 BIOS , failed.
    2. Put the p4 531 3 G CPU in and got the machine up, no issue.
    3. Cleared the CMOS, failed.

    I known the chipset of GX520 is intel 945, it can support P4 641. It seems BIOS can not support it.
    Would you please help me to add CPU Microcode to support P4 641?
    or modify the BIOS to disable the alert during POST

    Thanks in advance.:p

    Perhaps a BIOS update?

    That needs a CPU Microcode added to the Bios.
    It's not easily done.
    These guys are doing some work on that but their success rate seems to be low so far:

    Good Luck.
