I have a P4S800 E based system and the optical drives (Sony DVD-RW and
Plextor CD-RW) are stuck in pio mode 4.
I have the BIOS set to auto detect the transfer mode but the system seems
not to want to enable DMA. Could it be the cables or a driver that is not
installed?
Running Win XP with 1GB ram and BFG 6800 GT.
Thanks for any help in advance.

This may be matter of the Windows installer somehow getting "scared" of the
hardware and installing a de-nutted ide miniport driver instead of something
more interesting. I've only seen it happen once in a decent number of
installations, but this might fix you up as it did me.

Simply go into Device Manager and Uninstall the secondary ide channel, then
restart the system. This time through, Windows may correctly detect and
configure DMA drivers for the IDE channels. You may have to repeat this for
each IDE channel that is stuck in PIO mode, sometimes it fixes 'em all in one
pass...

D00d! I bow before your techie greatness.
Uninstalled and required two reboots for the proper drivers to install, but
it worked!
Many thanks!
