If stability is what you after, an Intel motherboard will not disappoint you.
The BIOS will be VERY limited though, with very few options. But, everything will work, including Sound Blaster Live's
if you are going Pentium 4, make sure its the Socket 478 version; so you'll have a future upgrade path
Pentium 3, you need to get the "B" stepping of the Intel 815, which is also known as the Intel 815EP chipset (no onboard video, 4 USB ports, support for Tulatin CPU's, etc..)
These boards also come with or without onboard audio & lan. There will be an "L" in the model for the lan model
