you can use the dd command, stands for diskdump i think..

man dd for more details.

OK.
How can I BackUp my startup boot disk to my hard drive.

You can use the dd command.

Per the man page, you'll want to use /dev/fd0 as the "input file" (if) and the name of the backup file you want to create as the "output file" (of). Here's an example:

Code:

dd if=/dev/fd0 of=floppy.backup

This will create a copy of the disk in fd0 to your current directory as floppy.backup.

Reverse the if and of values to create a floppy from the image.

Well, to be honest the man page for dd is not newbie material... An itsy-bitsy explanation wouldn't hurt.

BTW, anyone tried using dd to make ISO images from CDs and to copy floppies formatted in "unorthodox" ways (such as the 1.7 meg Micro$oft Windoze 95 and OS/2 Warp floppies)? I tried, but failed to produce successful copies.

I use dd to create ISO images of CDs all the time. I have had problems with some CDs though. CD's that are not closed sometimes give me problems.
