And this again seems to imply that the best boot order probably would be 1)
floppy, 2 ) CD, and 3) hard drive (keep it last). (IMO)
My opinion is very different. My view is that the hard drive should be
kept as first in the boot order.
Boot sector viruses aren't as common as they used to be, but they are
still around. If the floppy is set to boot first, and you happen to
have left a floppy in the drive, and that floppy happens to have a
boot sector virus on it, you're infected.
The risk may be small, but there's no reason to run it at all. The
hard drive should be kept as the first boot device, and it should be
changed to another device *only* when you need it.
