Matt, Could you put your coreboot .config file somewhere for us to look at?
The PCI ID of the graphics device (BDF 0:1.0) must match CONFIG_VGA_BIOS_ID in order for the vga option rom to get loaded. The alternative is to put the vga rom in the CBFS vgaroms/ directory with any name you want (e.g. vgaroms/matts_vga.rom) Seabios will then load it. You can disable CONFIG_VGA_ROM_RUN with this method. Also make sure you are building your seabios for coreboot. This would be clearer if your serial console was working. You will want CONFIG_EARLY_CONSOLE=y CONFIG_CONSOLE_SERIAL=y CONFIG_CONSOLE_SERIAL_COM1=y CONFIG_CONSOLE_SERIAL_115200=y CONFIG_DEFAULT_CONSOLE_LOGLEVEL_8=y Thanks, Dave On Tue, Oct 29, 2013 at 8:29 AM, Haywood-Evans Matthew <[email protected] > wrote: > Hi, > > I am presently looking at trying to get Coreboot up and running on an > ASUS F2A85-M system.
