IDE ATA/ATAPI controllers question.

    I have a motherboard with an Intel 875 chipset (Intel 82845E MCH and Intel
    82801 DB ICH4). This is probably because of the Beta and the chipset driver
    contained in it, but I am showing something a little strange in Device
    Manager.

    Under the IDE ATA/ATAPI controllers heading, I have 2 Intel 82801EB Ultra
    ATA Storage Controllers, designated 24D1 and 24DB.

    Along with that, I have 2 ATA Channel 0 and 2 ATA Channel 1 entries. Each
    ATA Channel entry says it can support 2 devices, so it would appear I can
    now support 8 devices on a 4 device motherboard. One of the ATA Channel 1
    entries does show my 2 CD/DVD devices with Target ID 1 and 0, which would
    seem to be normal.

    I tried deleting each of the main controller entries but it reinstalled
    itself. Could this be related to a SATA situation?

    Thanks,
    Clark

    Yes. If your BIOS allows the SATA device to be
    identified as a SATA (IDE) channel, and the
    software drivers also supports that, then you
    will have multiple ATA channels because the SATA
    is being identified as a ATA channel as well as
    the Parallel ADA (PATA) channel. So you have 2
    channels in your case.

    OK, Thanks--it seems to be working fine. No data corruption or anything.
    Normally in XP the SATA controllers are in a different area in the device
    manager. But I suppose that might depend on the motherboard and how it is
    set up.
