Although I haven't seen discussion of disassembling factory BIOS, I would think this has been discussed; why is this not routine, or effective, for these unruly Intel chipsets which can't get DRAM happy?
Of course it has been done. It won't tell you _why_ certain things are done, or what they actually do -- disassembling machine code doesn't give you source code.
Not that I would look forward to disassembling legacy BIOS, but if that's what it takes...
If that's what it takes I for one am not al that interested in supporting such chipsets.
