That would make sense. It did not perform the check before my change, so I saw
no reason to add it. As far as I know, there are no issues with it operating
the it does now.
I have no insider knowledge of EFI, PXE, or GRUB. I am just a sysadmin who took
a C class 10 years ago that is very frustrated trying to get a solution to
netboot both Windows and Linux for BIOS, EFI32 and EFI64.
