Chances are, with a bare bones system that you are describing, that you are not going to find a set of drivers like you want. What you may need to look for is the chipset drivers for the motherboard, particularly if you have on board video and ethernet.
from the looks of it this is a
VIA KM266 chipset. with a Relatek RTL8139 network card, and AC97/8233A VIA sound and S3 Savage4-PRO+ 266DDR graphics.
If you search around for those drivers, you will probably have better luck, but be advised, that just because they use this chipset on one system, doesn't mean that they didn't change up to something else. So no guarantees that this is yours chipset, but my guess is that this will get you pretty close
