Subject: VIA VT8366 and IDE/DMA?

Hi,

I have a K7 mainboard with VT8366 chipset, but I can't
turn IDE DMA on:

atlantis# hdparm -d1 /dev/hda

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


Writing to /proc/ide/ide0/hda/settings has no effect.


Can anyone give me a hint how to turn DMA on?

regards
Hadmut

VT8366 (KT266) is a north bridge and has nothing to do with IDE.

Compile kernel with VIA IDE support:

CONFIG_BLK_DEV_VIA82CXXX=y
