In several days I discovered that DMA is turned off on my HDD (fsck sayed it while Debian booting). Please, help me turn on DMA mode.

My hardware:
motherboard: Epox 8RDA3I rev 3.3 (nForce 2 Ultra)
hdd: WD1200JB (ide, 120gb)
cpu: Sempron 2200 (k7)

My software:
Debian lenny
kernel: linux 2.6.24-1-686
bootloader: grub 0.97-41


Today I upgraded my linux kernel to 2.6.25-2-686, but problem hasn't been solved yet.

I'm giving you some lines about DMA from '/var/log/syslog' file. Perhaps, this will help you to solve my problem:

Excuse me if I gave you something not very useful because I'm novice at Debian.
