+# grub-memtest.iso can be used for testing the various different boot modes,
+# using GRUB as an intermediate bootloader. Upstream GRUB only supports the
+# 16-bit and 32-bit boot protocols, via the "linux16" and "linux" commands.
+# Fedora add support for the EFI handover boot protocols, via the "linuxefi"
+# command, and, since 2019, remove support for the 32-bit protocol, aliasing
+# the "linux" command to either "linux16" or "linuxefi", depending on whether
+# you boot in legacy or EFI mode. Mageia follows Fedora, but restores support
+# for the 32-bit protocol, via the "linux32" command. Other distributions no
+# doubt do their own thing. The boot menu on grub-memtest.iso attempts to
+# support all these options.
