    I need to update my bios for the P4C-800 E Deluxe motherboard and
    would be happy to know the absolute correct way of doing it so there
    are no problems. Should I use the latest bios update which appears to
    be 1024, or is there a previous update that is more stable? Is using
    AFUDOS.EXE and booting into DOS the most foolproof way of updating, or
    does ASUS EZ FLASH work as well? While looking for info on what kind
    of boot disk I needed in order to get the system up to flash the bios,
    I found this site that contains boot disks for all the Microsoft
    operating systems if anyone is interested:


    Thanks for any help.

    I used ez flash and no problems. Just make sure you read the instructions
    and understand them if you use this method.

    1024 is a BETA version. The latest stable release BIOS is 1023.

    There are special restrictions for updating the last several BIOS
    versions on P4C800-E Deluxe. The BIOS cannot be updated using certain
    older versions of ASUS LiveUpdate or AFUDOS. Go to ASUS download
    pages for your motherboard and read the details on the BIOS download

    I always recommend DOS method, whether by USB flash drive, bootable
    CD, or floppy. Win-based methods (e.g. ASUS LiveUpdate) are
    responsible for more failed updates than DOS, being dependent on a
    more complicated (and potentially fragile) interaction between the OS,
    HAL, and system BIOS.

    After all, we're talking about Microsoft Windows here. ;-)

    I second this too, DOS is the best and safest way to flash BIOS. I always
    use the latest AFUDOS release. Works for me type in AFUDOS at the dos prompt
    and get set of options for the flash.

    Thanks all for the replies. So am I typing: afudos /ip4ced23.rom at
    the A: prompt in order to install the bios? I'm not sure about the i
    but I saw it in the instruction manual for the motherboard.

    That's correct, booted to a pure DOS environment, not a DOS window
    inside of Windows.

    One other thing; do I need to reset the bios to the default properties
    before I do the upgrade?

    Not before, but after the update.

    I just did the update. Thanks for the help. The strange thing is
    when I had bios 10019 installed only a little over 3 gigs out of 4 of
    memory was reported as being installed. With the new bios, 3.9 out of
    4 gigs is reported as being installed.
