A7A266 rev 03, what cpu ?, bios version unknown just got the board

  1. Hi,
    I just got 2 ATA266 boards rev 1.03 for my kids machine.
    Could someone help me with the following since I do not know the actual
    bios version

    What is the best cpu I can get it to run? I would like to get it to
    run a athlon xp if possible.

    What ram should I use? I know the board takes some of the older sdram
    133 which I have should I use it or
    avoid it

    If I had to update the bios to get the board to run an athlon xp how can
    I do this.

    That is fairly simple to answer by this site


    it shows that you are limited to a fsb266 cpu (so no barton and no
    fsb333 or fsb400 cpu).

    I would go fot the thorougbred 2400+. It is 2.0 GHz.
    Yes, avoid it, memory benchmarks are half numbers with sdram, but this
    might lead to just some 10-20 % performance loss totally for the PC

    I would go for some second hand pc2100 ddr ram. People sell them
    because they need more speed for an fsb333 or fsb400 cpu.
    How to do it ?

    Well, I will definitely recommend that you call a nerd friend to help

    Bios flash program:

    the aflash221


    beware if you have a7a266 or a7a266-e

    best regards

    I have that exact motherboard and am running a Athlon XP 2400 but the board
    does not recognize the chip properly. Even with the newest bios. You need a
    rev 1.10 to be able to take full advantge of the XP cpu. Some people do
    manage to get them working normally but mine wont post at 133 fsb due to
    multiplier woes.
    Tried unlocking multipliers on chip and still no go. Also tried running it
    in manual with the dip switches but still the same. Chip is running at
    100mhz fsb with 20x multiplier which is still better than my old Athlon
    1200. Other than that it has been a rock stable board.
    best of luck.
