my Asus m2n-mx motherboard seems not supported by Flashrom. The w39v040c was not found automatically, so I tried a forced read. The flashrom dump and the original bios are very similar but not the same.
That's OK. Most modern BIOSses save some system information in the Flash.
Motherboard: Asus m2n-mx rev. 1.06G
MCP61 + non-SPI flash. Interesting to hear about!
This chipset is not really supported yet. The flash write enable bit for LPC/FWH flash is the same as in MCP55, which is not yet enabled for MCP61. A board enable bit is GPIO31 on the IT8712F chip. To access this chip, the BIOS sets PCIConf[0x7B] in the ISA bridge to 0x19, accesses the port (0xA02 in your case) and restores PCIConf[0x7B] of the ISA bridge to 0x20. Just for reference: The board enable procedure is at 3E5D in the F segment.
