Creating DOS boot image to flash BIOS or firmware

Gavin Burns, from I Do Linux has a useful tip that you can use to upgrade of flash your servers BIOS and/or firmware. These utils are often DOS floppy images. Besides not having a floppy anymore these days, getting the server to boot a floppy image can present challenges too. Dell's DRAC often eludes me because the boot order won't choose the floppy (unless I hit F11 to get the boot menu, of course).

From the article Create DOS Boot Disk for CD or GRUB you'll learn to get the DOS floppy image and create a bootable ISO from it. You can burn the ISO to CD or use the boot image to add a GRUB menu option. Handy!
