Situations of Arrandale GPU
If Legacy boot, Arrandale GPU
supports 1366x768
for UEFI Grub2, the same as resolution of screen, higher than 1024x768
;
If UEFI boot, Arrandale GPU
supports 1024x768
for UEFI Grub2 at max, lower than resolution of screen, with graphical interface stretched horizontally.
Precedents with Solutions
In order to avoid graphical interface stretched horizontally, teams of CloverBootloader
have developed CsmVideoDxe.efi
and teams of OpenCore
have developed BiosVideo.efi
, used to make Arrandale GPU
loaded in the way of being loaded by CSM or Legacy Mode ,under UEFI_Mode, so graphical interface of UEFI can use higher resolutions from CSM or Legacy Mode, such as 1366x768, the same as resolution of screen, higher than 1024x768
.
Hope and Ask
Hope
- I would like so do
UEFI Grub2
andrEFInd
.
However,UEFI Grub2
andrEFInd
cannot loadCsmVideoDxe.efi
orBiosVideo.efi
.
Ask
- Is there a
Generic EFI Video Driver
to make all bootloader x64 to achieve that?
At least, supports to makeUEFI Grub2
andrEFInd
use higher resolutions from CSM or Legacy Mode, such as 1366x768, the same as resolution of screen, higher than1024x768
. - Is there any other way to achieve that?
