There was also the scenario where the CPU was 64 bit but the EFI was 32 bit.

Booting a 32 bit OS was fine, but 64 bit OS' generally came with a 64 bit bootloader, so you had to do a special song and dance to load a 32 bit bootloader with a 64 bit OS.

Those cheap 2006 Mac Pros also had 32 bit EFI

Polycarbon Macbooks too.

I remember creating the special boot disks with 32bit grub.

Mine (Acer Aspire One 756) had an EFI disguised as a BIOS. I only discovered it was EFI after a few years, when I inserted some bootable flash drive, opened the boot menu and saw an EFI entry for the flash drive there. Other than that, it’s as if they were trying to keep the EFI a secret (nothing in the settings hinted at it and I couldn’t get it to boot in EFI mode by default).

Forgot about this. That was annoying.

Ah yes, my big netbook (sold as the "2006 Apple Mac Pro") was so afflicted
