any more than that right now, just one action to prove that the boot really

You ask strange questions. Put memtest86 there.

Thanks for answering my strange questions. I just took a look at
http://www.memtest86.com
and downloaded some stuff. They emphasize that no operating system is
needed to be able to use it. That's good.

Am I correct in concluding that I can take any bootable floppy, for example,
and execute (in Linux):
cat /dev/fd0 > /dev/hda1
to make hda1 bootable and put in lilo.conf, say,

other=/dev/hda1
optional
label=abf

get the same effect as booting the bootable floppy, except that I would
boot from /dev/hda1?

I guess I can also use dd to copy just a few bytes at a time to /dev/hda1
to see what it does, one step at a time, when it boots.
