My new motherboard has a spdif in/out header on the motherboard.

Was just wondering if the old digital out two pin connector on my
toshiba sd-m1402 DVDRom is capable of supplying cleaner audio to the
motherboard audio through the spdif in header ? The spdif cable fits
both, but I'm wondering if both are on the same page technologically
speaking ;)

Yes, they are the same signal. It will most likely be better than the
analog cables, and quite possibly that digital audio over the IDE bus.

*Do realiize that that auidio is for audio CDs only, the audio from
DVDs comes off the IDE with the video, and is decoded in your player
software.

Thanks for the info. I'll try it out, but since I don't listen to too
many audio CD's, it'd probably be a waste of a good audio input ;) 

You wouldn't know where I can find the header cable/pci slot cover for
the spdif I/O would you ?

AFAIK, it is proprietary each manufacturer, or at least each seems to
sell a bracket for their boards.

Audio from an optical drive (other than that in a file such as a DVD or
other video format) can be transferred over the PCI bus with zero quality
loss... that's the whole point of digital, it makes no difference how it
gets to it's destination so far as quality is concerned.

If you can't find the header cable for your board you might start by
noting the motherboard's pin-header configuration and go from there.
Another make of (motherboard) optical dongle may work as-is or after
swapping a position of the wires in the connector, providing connector has
proper # of rows/columns. Another option is to make your own, relatively
easy since anyone could drill a suitable hole in a slot cover bracket,
attach an RCA jack or two and solder two wires to an appropriate
pin-header socket, if they're inclined to do so.
