To make a diskette using MS-DOS, use the rawrite utility included on the Red Hat Enterprise Linux CD #1 in the dosutils directory do the following:

Label a blank, formatted diskette appropriately (such as Boot Disk or Updates Disk). Insert it into the diskette drive. Then, use the following commands(assuming your CD-ROM is drive D:):

C:\> d:
D:\> cd \dosutils
D:\dosutils> rawrite
Enter disk image source file name: ..\images\bootdisk.img
Enter target diskette drive: a:
Please insert a formatted diskette into drive A: and
press --ENTER-- : [Enter]
D:\dosutils>

First, rawrite asks you for the file name of a diskette image; enter the directory and name of the image to write (for example, ..\images\bootdisk.img ). Then rawrite asks for a diskette drive to write the image to; enter a:. Finally, rawrite asks for confirmation that a formatted diskette is in the drive you have selected. After pressing [Enter] to confirm, rawrite copies the image file onto the diskette. To make another diskette, label that diskette, and run rawrite again, specifying the appropriate image file.

Note: The rawrite utility only accepts 8.3-type file names, such as filename.img.

The 8.3-type file name originates from the naming convention of eight characters, a period, and three characters for a file name extension. This naming convention supports file names between 1 and 8 characters, which cannot have spaces, and may not contain ? or _ characters at the start of the name

If you download an update image from http://www.redhat.com/ named something similar to update-anaconda-03292002.img , you must rename it as updates.img before you run rawrite .
