Creating Bootable Media

To update BIOS in MS-DOS, you must have a bootable floppy or another media with the MS-DOS operating system. To create the MS-DOS bootable disk in Windows XP/Vista/7, follow these steps:

  1. Place a blank floppy in the floppy drive.
  2. Open “My Computer”, right-click the icon of A disk and select “Format”.
  3. Select “Creating Bootable Media of MS-DOS” check box, press “Start”, confirm your action by pressing OK and wait until the procedure is completed.

A floppy media in Windows 95/98 and MS-DOS may be crated with the help of “format a: /s” in the command-line mode.

A lot of modern computers have not any floppy drives as they are outdated. But you may create a bootable CD or a flash-disk with the MS-DOS operating system. To create a bootable flash-disk, you will need utility to format it, for example HP USB Disk Storage Format Tool, and also the MS-DOS system files on a floppy, hard drive or in the form of a sample. The flash-disk should be formatted in FAT32, you need to specify the mode of bootable disk creation (Create a DOS startup disk) and the path to the MS-DOS system files. After the disk has been formatted, copy the file with the firmware on it.

To create a bootable CD, you can find the ISO image in the Internet or record your own image by using UltraSo (www.ezbsystems.com) or another program that is similar to this one. The file with your BIOS version and the firmware shall be added into the ISO image and then record it on the disk. Some motherboards’ manufacturers, for example Intel, may offer their own disk images for updating.
