BIOS Boot Order changes by itself

    I built a system for my daughter awhile ago using MSI's K8NGM2-FID
    motherboard. Recently, she told me that, occasionally, it is booting to
    a black screen.

    Her system currently has 3 hard drives:

    WD 80GB - IDE 0 master
    Samsung 250GB - SATA
    WD 500GB - SATA

    She originally had a different motherboard in the machine, and just the
    80GB drive, but when I rebuilt the machine with the MSI motherboard, I
    added the Samsung drive, and so I installed Windows XP SP2 as the 1st
    partition on the Samsung drive. I then set the boot order in the BIOS
    so that the Samsung was the 1st in the boot order.

    She added the WD500GB drive later.

    The first time I looked into the problem, it looked like the boot order
    in the BIOS had changed so that the WD 80BG drive was the 1st, and I was
    able to get the machine to boot to WinXP again by just changing the boot
    order back to having the WD80GB drive as the 1st.

    This happened a couple of more times in the last couple of weeks, and I
    flashed the BIOS from 3.50 to 3.70, hoping that that would solve the
    problem of the "changing boot order", but then the problem has happened
    again several times.

    It seemed like whenever the boot order changed, the WD 80GB was always
    set as the 1st in the boot order, so I just moved the WinXP partition to
    the 1st partition of WD 80GB (My logic for this is that, for whatever
    reason, the boot order was changing to some kind of default order, where
    the WD 80GB drive was the 1st, so if I put WinXP on the WD 80GB, that
    should always boot ok, even if the boot order got mysteriously changed
    back to the "default" boot order).

    We'll be watching to see if she continues to have the same problem after
    that last change, but I was wondering if anyone had encountered such a
    problem before, esp. with this motherboard?

    I have run across a similar problem at work awhile ago, with some IBM
    blades. In that case, IBM fixed the problem with a new BIOS, but I've
    been searching for any info on this problem with the K8NGM2-FID, but
    haven't found anything.

    BTW, I just got a response from MSI support suggesting that the problem
    may be the CMOS battery being dead.

    But, as I noted back to them, when it wouldn't boot, it wasn't going to
    the BIOS display, where I think it would normally go and display a CMOS
    checksum error message. Is that not the case with the MSI/AMI BIOS?

    A weak battery can cause all kinds of odd and unrepeatable behavior.
    Replacing the battery is something cheap to try. Sometimes battery
    failure is caused by improper grounding. Check and see if the board is
    touching the case or you have a misaligned support post.

    I talked to my daughter (I had built the system for her), and she
    reminded me that we had put in a new CMOS battery already, so we don't
    think that that is the problem.

    But, while talking about it, I think that I've come up with a "working
    theory" about something that has been puzzling me.

    We actually have 2 of these mobos: the one in her system, and also in
    one of my systems, which I use daily. The problem is only occurring on
    her system, so I've been trying to figure out why hers, and not mine.

    So, when I was talking to her this morning, I think that I realized the

    If you recall, when she was having the problem, her boot sequence was
    set to boot to the Samsung 250 SATA.

    On the other hand, while I also have a SATA drive in my system, my
    system has always been booting off of a PATA drive.

    This reinforces my "theory" that, for whatever reason, the BIOS on this
    mobo is intermittently resetting to the default boot order, where the
    PATA drive is booting 1st, ahead of the SATA drives.

    If this is happening, it is not happening in such a way that it is
    "corrupting" the BIOS settings, because we are not seeing any CMOS
    checksum error on boot.

    Now that I've re-configured her system so that WinXP is on the WD 80GB
    PATA drive, I guess we'll see. So far, it has survived on night, and
    hasn't had a problem, but I hope that this takes care of the problem for
    her :)...
