- Make sure the card is seated properly
- Make sure the cache ram is installed properly
- Try a different slot in case you're having mobo problems
- Try updating the system BIOS
- Try updating the card BIOS

Once you get it working...

If that card is a 1M or 2M you need to be using either a 2.2 kernel or 2.4.9 
or newer. The firmware in those cards doesn't work right with 64bit pci. 
Workarounds were added to the driver in the 2.4.8, and 2.4.9 timeframe, and 
2.2 doesn't support 64bit pci.

Good luck,
