Single grub.cfg For BIOS and EFI

[Marc Smith]

Hi,

In my Linux distro, I'm using a single grub.cfg and the user can boot
in either BIOS or EFI mode. However, some modules are specific to EFI,
and some to BIOS it appears.

Is there a way to test if we're "running" in EFI or BIOS mode in
grub.cfg and then use that to make a decision on what modules to load?

Something like this:
if in_efi_mode; then
  # Load modules (EFI mode)
else
  # Load modules (BIOS mode)
fi

Just not sure what to test to determine what mode we're booting with.


Thanks,

Marc
