Dear SeaBIOS,
using the AMD/ATI based ASRock E350M1 [1] with coreboot and SeaBIOS 1.7.2.1 as a payload and GRUB 2 (1.99-27 from Debian Sid/unstable) on the hard drive, letting coreboot load the VGA Option ROM and disabling »Option ROMs« in the menu »BIOS interfaces«
config OPTIONROMS bool "Option ROMS" default y # I set it to n. help Support finding and running option roms during POST.
I only see »AMD Wrestler …« printed to the screen (from the VGA Option ROM loaded by coreboot I guess) and I neither see the SeaBIOS header(?) with version nor the bootmenu. GRUB 2 does not show its (terminal) menu either and just shows funny, colorful characters covering the whole screen.
Linux is able to print something to the screen, but Linux’ Radeon driver complains too that it does not find the BIOS ROM and kernel mode setting (KMS) is disabled.
