Hello,
Back when Fedora handled disc drives as ide, I would use hdparm to turn
on DMA. Now that Fedora 8 seems to run them as SCSI devices, hdparm
can't tell them to turn on DMA. Any ideas how to get them blazing fast
again?
Its always done automatically by libata.

Thanks,
It would appear the issue wasn't DMA, but nvidia-config omitted
something from my xorg.conf that allows hardware acceleration for XVideo.
... and that was? Inquiring minds would like to know! :) Ric
The appropriate method would have been to make one change at a time in
the conf and test, but
I didn't want to spend that amount of time on it =P My guess is the fix
was in Section "Module".
Here nvidia-config only puts "Load "glx"". In a prior working xorg.conf
I had
Section "Module"
Load "dbe"
Load "extmod"
Load "type1"
Load "freetype"
Load "glx"
EndSection
At least one of those Loads is for the composite graphics, but I can't
remember which one.
The following was mainly for composite and extra features, thus I
wouldn't expect these to
be part of the fix:
Section "ServerFlags"
Option "AIGLX" "on"
EndSection
and
Section "Extensions"
Option "Composite" "Enable"
EndSection
From Section "Screen" to Section "Device" I moved:
Option "RandRRotation" "True"
Option "RenderAccel" "True"
and added to Section "Device":
Option "AddARGBGLXVisuals" "True"
Option "DisableGLXRootClipping" "True"
for composite.
