grub4dos uses an older version of the kernel boot protocol
ELF ⇒ real-mode probably easier
hard to retain BIOS memory
kexec_test exercises most of the interesting code paths that are needed to load a kernel (mainly BIOS calls)
booting another OS will work — AS LONG AS that OS doesn't make any BIOS calls
would it be possible to load
SeaBIOS
and then use that to boot
any
OS without restriction?
