    Neither exists. Just so you know: My motherboard (Asus A7V133) has 2
    integrated IDE controllers. Besides the native VIA controller there is a
    Promise ATA100. The following are the relevant snippets from dmesg:

    atapci0: <VIA 82C686B UDMA100 controller> port 0xd800-0xd80f at device 4.1
    on pci0
    ata0: at 0x1f0 irq 14 on atapci0
    ata1: at 0x170 irq 15 on atapci0

    atapci1: <Promise PDC20265 UDMA100 controller> port

    (yes, I use atapicam)

    and ls /dev/ad*:

    Let me know if you come up with any suggestions on what I should try next.
    Thanks ever so much!
