[coreboot] ASUS M488t-m

[Dave Houston]

Afternoon all,

I have an ASUS M488t-m which is very close to m4a785-m. I am currently making sure that I have a method to reflash should my build is bad ( which it most likely will be ) and I have been doing some digging regarding my Flash chip. The data sheet suggests that the current chip is 16Mb http://www.alldatasheet.com/datasheet-pdf/pdf/272751/EON/EN25F16.html. 

High resolution of mainboard: http://media.ldlc.com/ld/products/00/00/77/92/LD0000779214_2.jpg

I have included all relevant output below. Is there any gotchas I should be aware of and is there a good flashing solution (I'm not adverse to buying a hardware solution ) ?
