Thanks, committed in r2995.


  +	dev = pci_dev_find(0x8086, 0x2440);     /* Intel
ICH2 LPC */
 +	if (!dev) {
 +		fprintf(stderr, "\nERROR: ICH2 LPC bridge not found.\n");
 +		return -1;
 +	}
 +
 +	/* use GPIOBASE register to find where the GPIO is mapped */
 +	port = (pci_read_word(dev, 0x58) & 0xFF80) + 0xE;
Maybe I have a thinko, but shouldn't this be 0xffc0 instead of 0xff80?


  +
 +	val = inb(port);
 +	val |= 0x80; /* Top Block Lock -- pin 8 of PLCC32 */
 +	val |= 0x40; /* Lower Blocks Lock -- pin 7 of PLCC32 */
This is board-specific I assume? Did you trace the connections going to
the ROM to find the specific lines?

You are correct ... feel free to fix that.
Apparently this patch needed *a bit* more work. :P

Yes. I traced them across and through the board to under the
southgate. After I got some hints from the 'AWDFLASH' page
provided by the stock BIOS, I poked at the I/O port,
measured the voltage at those pins ...
