Some degree of VBE is required for Windows to boot in BIOS mode (and even in EFI mode before Windows 8 for really tedious reasons). I'd expect it to be fine for basic mode setting, but you're still stuck with the modes the card firmware provides which means it's probably 4:3 ratios.
- bibaheu 4y agoWhat are those tedious reasons? Like when booting on very old hardware, you got a Vista-like splash screen on Win7?
- mjg59 4y agoSome part of the boot stack expected to be able to make VBE calls to set the inital screen mode before loading actual drivers, which means hardware that wants to support Windows 7 needs to provide a CSM layer to support that even if it's otherwise booting via EFI (the CSM layer just rewrites VBE calls into EFI GOP calls, so the graphics card doesn't need to provide VBE itself)
