в ядре
Device Drivers --->
ATA/ATAPI/MFM/RLL support --->
[*] Generic PCI bus-master DMA support
[*] Use PCI DMA by default when available

в биосе тоже вроде дма включено.

а когда пишу hdparm -d 1 /dev/hda то:

localhost ~ # hdparm -d 1 /dev/hda

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

Code:

При конфигурации ядра для работы DMA нужно указывать правильный контроллер IDE, что зависит от чипсета. Generic -- это самые общие функции контроллера...

Не поверишь - с этой материкой у меня и были проблемы. дма не удалось влючить даже под виндой.
С тех пор я к VIA отношусь не очень хорошо.
Совет - меняй "маму", потому как геммороится ещё будешь долго. Либо просто про дма - забудь.
