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?
