====== Grub ======

''Grub'' is a bootloader for X86 machines.

===== Booting Floppy Images =====

The ''syslinux'' package contains a loader for floppy images that can be booted
using ''grub''. When both packages are installed, the procedure is quite
straight forward:

  * optionally create a subdirectory in ''grub'''s root to contain the specific stuff
  * copy the ''memdisk'' binary and the desired floppy image to the above directory
  * add an entry to ''grub'''s config like so:
<file>
title Boot some floppy image
kernel /dos/memdisk
initrd /dos/BOOT.IMG
</file>

===== Defaulting to previous Selection =====

Edit ///etc/default/grub//, add:

  GRUB_DEFAULT=saved
  GRUB_SAVEDEFAULT=true

Then recreate grub config:

  grub2-mkconfig -o /boot/grub2/grub.cfg

This should do the trick, works at least with a recent Fedora 39.
