Hi all,
I am experimenting Coreboot on an Intel Rangeley based system using Seabios (master) as payload. The system does not have VGA adapter. So I added sgabios.
$ ./build/cbfstool build/coreboot.rom print
coreboot.rom: 8192 kB, bootblocksize 720, romsize 8388608, offset 0x400000
Alignment: 64 bytes

FvFsp.bin 0x37ffc0 raw 372736
(empty) 0x3db000 null 150760
However I don’t see Seabios boot menu on console. The system pauses after Seabios is loaded and then starts OS. There is no problem with Coreboot and Linux console output, but no output from Seabios is seen at all on the console.

Seabios (master) is pulled and automatically built as part of the coreboot build. During the build, it popped out a menu to for VGA hardware type.
VGA Hardware Type
> 1. None (NO_VGABIOS)
2. GeodeGX2 (VGA_GEODEGX2)
3. GeodeLX (VGA_GEODELX)
4. coreboot linear framebuffer (VGA_COREBOOT) (NEW)
choice[1-4]:
I tried both 1 and 4. Neither of them seem to work. Did I miss something?
Thanks!
