How to enable DMA at boot time
Following the tips in another thread, I have successfully used hdparm to enable DMA and to measure its improvement on my IDE hard disk.
Now I want to enable DMA at boot time. According to the kernel docs (ide.txt.gz and kernel-parameters.txt.gz) I should be able to do this with the kernel parameter ide0=dma, but it doesn't work. Am I doing something wrong, or is this not supported? If not, should I enable DMA with an hdparm command in an init script, or do something else?
I'm using kernel 2.4.18-k7 in Woody.
Motherboard: Micro-Star K7T Pro2-A (MS-6330)
Disk: Maxtor DiamondMax UDMA100.
Any help is appreciated.
