How does one go about verifying that DMA is enabled on
their harddrive?
hdparm /dev/hda
(or whatever the name of your hard drive is; "/dev/sda" for SCSI or
SATA).
What kind of video is it? Dvd? Do you use the regular video drive
provided by X, or an accelerated one? Might make a difference.
You might also want to try enabling ultradma, as well. Hdparm says
messing with that is dangerous, but, honestly, I never saw any kind of
harm doing hdparm -X etc /dev/some-drive. If not possible, hdparm
outputs an error, that's all.
Check 'hdparm --help' for the -X (case) option. This shall bring you to
the best possible transfer speed for the drive.
