Greetings,
i am trying to get coreboot running on x230 and have some trouble regarding the execution of the vga option rom.
As far as i understand seabios should load all option roms existing in cbfs, but it won't.
Only if i set CONFIG_VGA_ROM_RUN=y vga option rom gets loaded but whether coreboot nor seabios output is displayed. Only a blinking cursor idles until boot continues.
coreboot.rom: 12288 kB, bootblocksize 1936, romsize 12582912, offset 0xb00000 alignment: 64 bytes, architecture: x86
Name Offset Type Size cmos.default 0xb00000 cmos_default 256 cmos_layout.bin 0xb00140 cmos_layout 1984 pci8086,0166.rom 0xb00940 optionrom 65536 cpu_microcode_blob.bin 0xb10980 microcode 22528 config 0xb16200 raw 5457 revision 0xb17780 raw 570 (empty) 0xb17a00 null 34136 fallback/romstage 0xb1ff80 stage 73116 fallback/ramstage 0xb31d80 stage 74814 fallback/payload 0xb44200 payload 55077 pci8086,1502.rom 0xb51980 raw 61952 bootsplash.jpg 0xb60bc0 raw 59966 (empty) 0xb6f640 null 461144 mrc.cache 0xbdffc0 mrc_cache 65536 (empty) 0xbf0000 null 63512
Any idea what is going wrong here?
Best regards,

If i am correct this comes from src/northbridge/intel/sandybridge/acpi.c line 95:

Just to double check: did you add the vgabios with or without compression? coreboot only supports uncompressed vgabios images (while seabios allows them compressed as well, if the name matches)
