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)

What's the matter?

Thank you.
