If the PROM contents are bad due to runaway software or whatever reason, does the board become a doorstop, or is there a fail-safe method to reprogram it? Some mainboards have a fail-safe loader. Some have two copies of the firmware, and you only flash one copy at a time. Some turn into doorstops if the flash doesn't work. :-( The two copies method could be useful for a development board. Wire the select pins to a toggle switch. Easy way to safely test new firmware, and quickly recover if it doesn't work. _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
