My next question, how to proceed with fitting another LPC BIOS? I am under the impression that I can source any LPC BIOS chip to replace substitute my current one, use AWG30 wiring to connect the new chip over my current chip, and connecting the OE# pin of both to a switch of some sort. The difficutly is that LPC runs at 33MHz, and the chip is a 32-pin VSOP. I am not sure what mode (FWH/LPC) the device operates in when booting. This may help to eliminate some connections if using LPC mode. There is mention of an A/A Mux mode, but I believe this is used for an EEPROM programmer, not a computer (normally). Looking more closely at the data sheet, it may be possible to tie some pins to a fixed logic voltage (e.g.: TBL#, WP#, IC, possibly GPI pins, R/C#, AD pins). Any help suggesting how to proceed with retrofitting a second BIOS chip to the board would be very helpful. Regards, Michael Cassaniti
