Hi. Please,scomeone,add these files to coreboot project (attached archive).
I've fount that Asus L1N64 is very similar to Asus M2N-E as hardware
(mcp+ite8716f+adt7475) and pcb
So I fix m2n-e files for diffrent socket *Socket_F*, add *select
DIMM_REGISTERED* , turn on *device pci e.0 on end*
I can't read any information from i2c-tools
. I have the similar log from Asus M2N-E, I could continue after I replaced
memory stick to last dimm.
At this board Asus L1n64 two first dimms connect to CPU0,others - to CPU1,
I've tried all variants - nothing change. Maybe someone can explain how
these two mcp55 aree connected between them to nforce 680a.
Scheme of this board,look at attached image
