I bought a couple of these. The only 2 cards I have that work reliably are:
-- the voodoo3 ( can play ppc quake2 with no problems )
-- and the rtl8090 ( can't remember if this is the exact model number ), a 10mbps network card.
Nothing else works afik due to dma and driver issues. Someone, Michael Boehmer?, is working on new firmware. Last I read, the firmware was working but needed some finetuning before release. The boards will have to be shipped to be updated. No user flashing.
Btw, I'm not an "expert" on these boards. Just a user/owner. Still waiting for news myself.
