 Hello, here's here.

/etc/rc.local
hdparm -c3 -u1 /dev/hda ( -d 1 is okay too, if it can't, it wont) (anybody have a reason not to do this? curious.)

idebus=66 to lilo.conf on the append line

Been doing both for years now, no probs yet.

hdparm -i /dev/hda tells lots of info, for more use a -I (drive speaks directly).
The * with hdparm -i will tell you what your drive is running at as is.
The test performance type options, -T -t are a must too. (tune with)
I remember playing with the other options, just don't remember what happened....No smoking drives though!
You get warned or simply refused if ya try something to silly, but then again...|;P)

Hope that helps,

bests,
eddie
