maybe this will help -

 I enabled the HD optimizations during my Mandrake 7.2 install.
Unfortunalty under heavy HD load my system would experience CPU
spikes that would reneder everything inoperapble for 1-2 seconds
at a time.  This was very anoying and not what UDMA is supposed
to do.  My xfers were also pretty slow.  So I dug into /etc/lilo.conf
and saw that Mandrake and put a kernel option in there that reads :
append=" ide1=autotune ide0=autotune" .  I dug into the Linux Mini-how-
to for UDMA and found it stating that one should try this instead:
append=" ide0=dma ide1=dma" .  So I created another entry in lilo.conf and
replaced autotune with dma and rebooted.   I then chose that linux opion on
reboot and Wow what a difference.  Just like things are supposed to be.
 I copied about 200 megs of mp3s from one IDE to another and I had 0
interuptions.  and teh xfer is very fast. :) No it could be my older ata/33
and BX chipset don't work well with the autotune parameter but
using plain old dma works much better.
