probably a good guess. Another way I found it on one board was to try every combination of GPIOs until the FLASH started working. Not fun, but pretty fast if you write a program. > I can always cut the traces and hard-wire to +12V but I'd like to see if I > can't do this programmatically.

Or put a PCI bus analyzer on the machine, run the flash program, and watch the IOs. It's not going to be fun. I still don't see how running under Bochs helps with the chipset but maybe I missed something. > Now I know that every motherboard is different and that there may be other > things locking me out, but generally speaking is there an "industry standard" > way of enabling/disabling BIOS reflash? No, the goal is to make it hard for you to reflash. So the vendors keep coming up with new ways to hide this. Very annoying! ron _______________________________________________ Linuxbios mailing list [EMAIL PROTECTED] http://www.clustermatic.org/mailman/listinfo/linuxbios
