If you mess up the BIOS prom, all that does is prevent the card from being console. It can still be reprogrammed. But if you mess up the FPGA serial prom, you're hosed.... you then have to reprogram it externally. Note that when we find a bug, we'll first try to work around it in software. Reprogramming the FPGA is a last resort! _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
