I tried the 2.4.17-rc2 kernel and I was able to boot. (but I'm not with 2.4.9, 2.4.12-ac5 and 2.4.16)

Unfortunately, when I try hdparm -d1 /dev/hda, I get the same errors 

hda: timeout waiting for DMA
ide_dmaproc: chipset supported ide_dma_timeout func only: 14
hda: irq timeout: status=0x58 { DriveReady SeekComplete DataRequest }

What can influence the DMA on the BIOS else than the disk configuration?

I always get this PCI bus warning : 
ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx

Maybe I have somthing wrong with PCI bus that change everything???

PS: I have the lastest asus BIOS update (1003).
