Use the /proc interface:

/proc/ide/hd[a-d]/settings

To set DMA (for example):

echo "using_dma:1" > /proc/ide/hdc/settings

I do:

echo "using_dma:1" > /proc/ide/hdc/settings
echo "io_32bit:1" > /proc/ide/hdc/settings
echo "unmaskirq:1" > /proc/ide/hdc/settings
echo "keepsettings:1" > /proc/ide/hdc/settings

in /etc/conf.d/local.start.

Thanking you good sir.


May I then assume, that hdparm is essentially unnecessary, aside from
changing the DMA mode and changing power saving settings?
(and getting a nice concise list of info about a drive)

Cheers,
