    I have a system that uses the Aopen AP5VM motherboard with AMI v2.50
    BIOS. I am trying to upgrade to a 40 gig IDE HD and am getting errors
    evry time. Ihave tried with Windows 2000 Pro and get a kernel
    exception. When I try with W98 I get a dos extender error. I have
    tried with Disk Manager to get around the BIOS size limit, but still
    get errors. I've tried various seemingly plausible variations in the
    install, but no joy.

    Ideas? Pointers to online material?

    I would flash the BIOS. It looks like there is a problem with your BIOS
    version according to the AOpen site:



    Just make sure you match the BIOS to your board revision number.

    If you want to use the Disk Manager, it should work after that. I'm not a
    big fan of it, but it does work. There can be problems if you ever try to
    restore a backup image such as from Norton Ghost or Drive Image Pro, but if
    you don't use them it shouldn't be an issue. In my opinion, the best
    solution would be a hard drive controller card. The reasons for this are
    twofold. First, they support at least a 137GB hard drive, and second, your
    motherboard uses PIO4 mode ATA interface which is extremely slow by today's
    standards. This mode transfers data at 16.6MB/sec max. where as most hard
    drives now support 100 or 133MB/sec. transfer rate. These are ATA100 and
    ATA133 interface. The cards a re very simple to install in an open PCI slot
    and are relatively inexpensive, especially if you shop on eBay. Information
    on these cards can be found at www.promise.com and you can look for prices
    on www.pricewatch.com. Your hard drive is more than likely an ATA66 or
    ATA100, so I would go with the ATA100 card which is Promise model Ultra100
    TX2. I just looked on eBay and these are available there for $15-20.

  3. Dave,

    I ran into similar problems when upgrading a client's older
    AP5VM. I finally had to use a Promise Ultra66 PCI card to get
    around the BIOS limitation.

    You can find similar Promise cards for dirt cheap on eBay.

    Good luck,
