a) setup the most minimal northbridge memory registry b) detect spd to find memory parimeters c) set the spd parimeters in the northbridge memory registry d) startup memory
Is this correct??
a) sounds suspicious. No "minimal" setup, but rather "those registers of the memory controller that don't have to be setup via c.
The main question I have is how do I know which of the northbridge memory registers need to be setup on initially?? If they are to use their default values to I even need to include them?? Or should I just set them all up??
Heh. :-) That is the tricky part. You have to read the docs, and try to understand, and you can compare the registers to those of the legacy bios.
Some chipsets have a "bios porting guide", but except for AMD chipsets, they are usually hard to get.
