    SubjectUDMA on ASUS P5A
    Hi all!

    I'd like to enable DMA transfers on a ASUS P5A, kernel 2.2.6.
    I have it enabled in the BIOS, but I still get the following:


    PCI_IDE: unknown IDE controller on PCI bus 00 device 78, VID=10b9, DID=5229
    PCI_IDE: not 100% native mode: will probe irqs later
    PCI_IDE: simplex device: DMA disabled
    ide0: PCI_IDE Bus-Master DMA disabled (BIOS)
    PCI_IDE: simplex device: DMA disabled
    ide1: PCI_IDE Bus-Master DMA disabled (BIOS)
    hda: Maxtor 91000D8, ATA DISK drive
    hdc: Pioneer CD-ROM ATAPI Model DR-A24X 0102, ATAPI CDROM drive
    hdd: IOMEGA ZIP 100 ATAPI, ATAPI FLOPPY drive


    and later:

    /dev/hda:
    setting multcount to 16
    setting using_dma to 1 (on)
    HDIO_SET_DMA failed: Operation not permitted
    multcount = 16 (on)
    using_dma = 0 (off)

    Slow devsel. Master Capable. Latency=64.
    Non-prefetchable 32 bit memory at 0xe0000000 [0xe0000000].
    Bus 0, device 1, function 0:

    Min Gnt=2.Max Lat=4.
    I/O at 0xd800 [0xd801].



    What's the matter?

    Thank you.
