Do you use hdparm to get these speeds? Check if DMA is on by using hdparm -i /dev/hd? (change to your device of course) , if it's not try e.g. hdparm -d1 -X66 /dev/hd? (X66=ultra DMA 2 if your device supports that or even try multiword, example X34=multiword DMA 2) Brien On Monday 01 September 2003 05:51 pm, JD Gray wrote: > I use an SiS SATA controller that uses the siimage driver > (drivers/ide/pci/siimage.c) I have an -ac 2.4 kernel that uses version > 1.06 of this driver, and it works very well (~65MB/s).
