Running MemTest86+

Once in a while you begin to suspect your RAM and want to test it. Booting off floppy (huh?) or USB can be a pain, and cutting an ISO gives WALL-E unwanted business. The easiest option on Debian is to apt-get install memtest86+ and then add to your grub's (I use Grub4Dos) menu.lst the following lines

title Memtest86+
find --set-root /boot/memtest86+.bin
kernel /boot/memtest86+.bin
and boot to this utility.

(2020/12/15) Now of course there's memtester which does not need you to reboot the computer but cannot test all areas of RAM.
