The chip set is NVidia, exactly the same as a Gigabyte M57SLI,

AMD Athlon(tm) 64 dual core
Nvidea MCP55
PMC Pm49FL004

The board is a DFI Infinity NF570, and I have done a little tutorial on 
it, (the code changes from M57SLI to NF570 are trivial)


I have no real knowledge of BIOS chips, and the handbook just describes 
the "Award BIOS" as though this is all you need to know.  At my stage of 
learning I just do not know about  "SPI and not FWH/LPC", (yet).

If I know exactly what to order, I can probably get them, but anything 
with 49FL in it just comes in 4M bit or 8M Bit.
