New subject: vga & serial debug support when building grub2 as payload

25 Sep 2013


      I think that's the same vendor ID as the Pixel, so perhaps the Pixel
VGA bios in "snm_2137.dat" in "3rdparty/mainboard/google/link" will
work?

Hello Paul,
David,
...
I have the same problem with VGA, I am looking into my
coreboot settings:
...
CONFIG_VGA_ROM_RUN=y
CONFIG_VGA_BIOS=y
...
CONFIG_VGA_BIOS_ID="8086,0166"
CONFIG_VGA_BIOS_FILE="./src/vbios.bin"
...
I do not see any of:
vbios.bin or vgabios.bin in directory src/ I am using Cougar Canyon 2 or
equivalent which is Emerald Lake 2.
...
What PCIe VGA should I use (I
think I know how to discover this one)?
...
How I can get vbios.bin
for these boards (I assume the vbios.bin) is the same for both of them?
...
Thank you,
Zoran

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_ROM_RUN=y
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.
...
...
...
...
What board do you use?
If coreboot successfully runs the VGA
BIOS/Option ROM (and if it is
...
...
needed), GRUB 2 should be able to
display text on the monitor. I am
...
...
successfully doing that on the
ASRock E350M1.
...
...
Do you get graphics with SeaBIOS as a payload and
letting SeaBIOS run
...
...
the VGA BIOS/Option ROM?
...
(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!
...
...
That should work. Do you get serial
output with coreboot? Do you get
...
...
serial output from the GRUB
installed on your hard disk?
...
Does TankTang also need to set
GRUB_GFXMODE (ie GRUB_GFXMODE=640x480) in grub.cfg?
