I bet you can. There will either be jumpers on the board to disable the on
board graphics and sound, or it will be a setting in the BIOS. On my board
it's a jumper labelled "VGA" which switches between on-board graphics
(shared memory - urgh!) and PCI card. It's very unusual not to have a board
with this facility - even old 386s had this ability.

You mean do something like take a trip to www.minidisc.org and build a TTL
to Toslink converter (projects section) and connect to the S/PDIF output on
the board.... yes that works very well. Of course, it's far more exciting
when you realise you can make a similar unit using a Toslink reciever and
connect to the S/PDIF input, giving you digital input from your MD rather
than CD-ROM.
Here's how I would set up the system:
S/PDIF input on board - Toslink reciever module - Socket on PC for in
from MD.
S/PDIF output on board - Toslink transmitter module - Socket on PC for
out to MD.
Sound card CD audio - CD-ROM analogue audio output
If you want to record digitally from a CD, then rip it to the hard drive
with one of the many "CD ripper" programs available free on the net then
playback to MD. You can then "normalise" the CD tracks to make them all the
same volume which gets around the problem of many portables not having
digital record levels.
Hope this helps!
