I was able to start up the internal graphics core, but unfortunately only in text mode. I think the problem in the initialization in funcution - internal_gfx_pci_dev_init and rs780_internal_gfx_enable (src\southbridge\amd\rs780\gfx.c).
The lack of documentation does not give me the opportunity to properly install the necessary bits for gfx.
Thanks for any help.

Subject: [coreboot] Porting coreboot on ASUS M5A78L-M LX3


I need help to porting coreboot Asus M4a785m on Asus M5a78l-m lx3.

I'm trying to porting coreboot on the motherboard Asus M5a78l-m lx3 (rs780l/sb710). I cannot find documentation for the northbridge rs780l.

My configuration:  cpu - Athlon 2 x2 220 (K10), memory - 2 + 2 Gb DDR3, video - Asus GT520, sata segate hdd 500Gb, sata asus dvd-rw.

I have a positive result for the configuration with memory 2Gb and external video card Asus GT520. I can load Linux kernel 2.6.

But, i have two problems:

1. I cannot load coreboot with internal graphics card (hd 3000). Coreboot stops loading and to print on console "Calling option ROM…". May be the problems with gfx configuration?

2. I cannot run Linux with memory 4Gb. Coreboot is loading, SeaBios is loading too, but  Linux stop load on usb3-2 and ata1 setup. May be the problems with memory map?

Please, help me. I can provide all the necessary information from the log coreboot, SeaBios and Linux.
