Re: [coreboot] Troubles with 17'' WXGA on Roda RK886EX

[zxy__1127]

Then need to let it run correctlly first.
3 steps:
1)  CONFIG_VGA_BIOS_ID="8086,27ae"
2)  modify VGA rom in hex, offset 46h =0xae
3）ignor the checksun error in payload(seabios....).

may be there are  better ways,let me know :-)

Thanks!

Hi

I think it's a issue about lvds setting in VGA rom.
You can get the vbios from Intel's web site, and you need to modify it to fit your screen.
8086/27ae 8086/27a2 just different ID,because your have let the VGA rom run, so it doesn't matter  :-)

It should be easier to grab the vbios from the existing BIOS. According to the logs that were attached, at least coreboot did not run the vbios at all.
