Embrace & extend tactics from Intel? I think so.

The firmware in my alphas includes an x86 emulator for running the BIOS on VGA cards and sometimes SCSI cards.

Its quite possible that the RIVA128 would co-exist with the TNT. I'm pretty sure that you can have >1 TNTs in a box. -- Doug Rabson Mail: dfr@nlsystems.com Nonlinear Systems Ltd.
