P3B-F and Celeron 1400 (Tualatin)

Discussion in 'Asus' started by DIS Towncrier, May 14, 2007.

  1. I have recently come into possession of a P3B-F motherboard as a
    replacement for an aging Abit BH6. I did some preliminary poking
    around the internet and was under the impression that this motherboard
    transplant would be a no brainer. I had not anticipated the fact that
    the engineers at Asus apparently made a concious effort to NOT
    officially support the Celeron 1400 processor (CPUID 06B4).

    I have seen several pages devoted to patching the 1008.004 bios to
    support this processor, but have noticed conflicting suggestions
    regard whether or not to try to include the 06B4 microcode in the
    patched bios. Most of the instructions are for the P2B motherboard. I
    have no experience whatsoever with Asus motherboards and was looking
    for the easy solution to this problem.

    I realize that I can simply ignore the warning message and that the
    system will work without the patches, but ideally I would like to
    patch the bios and be done with it.

    You don't have to flash upgrade the BIOS. There is a procedure
    based on CTMC from Heise magazine. That is what I used to
    fix the microcode on my P2B-S that had a Tualatin fitted to
    it (using a slocket). (The file CTMC.ENG is English text.)


    Basically you use CTMC to extract a 2KB microcode from a
    BIOS known to carry the proper microcode. Then use CTMC to
    store the 2KB microcode in the microcode cache in the
    Award BIOS.

    The microcode cache will remain valid, as long as you
    don't unplug the processor and put a different processor
    in place. If you swap processors a lot, you'd have to
    repeat the CTMC procedure to refill the microcode cache
    when the Tualatin is put back.

    Since there is no flashing operation (i.e. flashing the
    whole BIOS), there is relatively little danger of something
    bad happening.

  3. Thanks for the reply, Paul. I will give this a try as soon as I get a
    chance. I appreciate your help.
