Oh thank you! I have changed to none now. BTW, could the source set it to none automatically if add the VGA BIOS? I have used this for months and don't know it's flawed... But the same setting none+VGA BIOS+SeaBIOS also not work for T440p to show bootloaders. > This is very odd. The software interface is 100% the same as in the T420 > case.

I have swapped the disks between the two and tested, the result is the same. Could it be some issues with hardware? How to debug like get logs from libgfxinit/grub? I can pull the logs for you. > Wasn't this 2? Yes that's the same, sorry for mistake. > For systems from the last 10 years, Windows only needs the VBT, AIUI.

I see the option is on by default for both T420 and T440p. 2020年3月16日 17:38 来自 [email protected]: > Hello Dalao, > > On 16.03.20 09:23, Dalao via coreboot wrote: > >> 1, Run VGA Option ROMs+Legacy VGA text mode+VGA BIOS+SeaBIOS: >> > > this combination is flawed.
