Hi Maillist,
I am a bios engineer from Byosoft.
Unfortunately, I meet 2 questions about building
Grub2 as coreboot's payload.
(1)How can I enable vga support during post?
I have configure the following token:
CONFIG_VGA_BIOS=y
CONFIG_VGA_BIOS_ID="8086,0166"
CONFIG_VGA_BIOS_FILE="./src/vbios.bin"
But it seems that it doesn't make sence.Is
there something need I to do in Grub2 to support vga.
(2)How can I enable serial prot debug after Grub2
Payload is loaded?
I have add the following to grub.cfg and use
"grub-mkimage -c ./grub.cfg ......." to make the Grub2.elf.
serial
--speed=115200 --unit=0 --word=8 --parity=no --stop=1
terminal_input
--append serial
terminal_output
--append serial
But it doesn't work after grub2 payload is called!
I need your great help!
Thanks,
TankTang
