Comment 8 for bug 19885

As a workaround for the memory-testers that cannot wait, just boot it
from a floppy:

1) insert a Floppy
2) cat /boot/memtest86/memtest.bin > /dev/fd0
3) boot from floppy

This will bypass GRUB and overwrite a bit of these "reserved" memory
regions... I don't think this is a problem (it isn't on my machine).

Another source that tells that some of these regions can be overwritten
without problems is the memtest86 README:
 zless /usr/share/doc/memtest86-3.2/README.gz

Probably these tables (etc) are only used by an OS... but since we only
run memtest there's no problem at all.
