Is it possible to check at run-time on which platform we are running.
Specifically, any way to distinguish between EFI and legacy BIOS?

TIA

Something like below should work (requires grub 2.00, not 1.99):

[CODE - part of grub.cfg]

if [ "${grub_platform}" == "efi" ]; then

    set _GRUB_PLATFORM="UEFI"

    

    if [ "${grub_cpu}" == "x86_64" ]; then

        set _UEFI_ARCH="x64"

    fi

    

    if [ "${grub_cpu}" == "i386" ]; then

        set _UEFI_ARCH="ia32"

    fi

    

    insmod efi_gop

    insmod efi_uga

fi

if [ "${grub_platform}" == "pc" ]; then

    set _GRUB_PLATFORM="BIOS"

    

    insmod vbe

    insmod vga

fi

[/CODE]

Regards.
