I've got a HP Pavilion desktop that has an ASUS OEM motherboard model A8M2N-LA. Manufacturer details are here (there is a nice schematic): http://tr.im/qHw7
It appears to have an MCP51 southbridge, ASUS A8000 SuperIO, a "GeForce 6150 LE" northbridge, Pm49FL004 flash, and also has a Nvidia C51PVG chip on it. I have no idea what that last chip is, but I saw some references to it in an earlier thread here http://tr.im/qHvZ .
I don't see the MCP51 listed in the supported southbridges, but then I saw some reference to mcp51_early_setup_car.c in this thread http://tr.im/qHr8 so maybe some headway has been made?
I'm really interested in getting the memory hole enabled so I can actually use all my memory... Would that be possible with coreboot?

I'm afraid this board will not be supported anytime soon. Both the NVIDIA C51 and MCP51 are not supported and we generally don't have _any_ NVIDIA datasheets, so this will not change a lot...
(Only MVIDIA MCP55 and CK804 are supported because a developer had NDA datasheets back then, but he no longer has access to them also)

Nice, thanks! We didn't yet have a dump from an A8000, nice to see that the code seems to work ok. Will link to it in the superiotool wiki page.

Looks good so far. If you have a working backup chip (and the chip is in a socket, not soldered) then you can try to erase the chip and write random data on it to see if flashrom supports your board out of the box or if any special flashrom code will be required. That would be helpful.
But please only attempt this if you are sure you can recover in case the flashing doesn't work.
Uwe.
