Making Installation Diskettes
You may need to create a diskette from an image file; for example, you may need to use updated diskette images obtained from the Red Hat Linux errata page:
http://www.redhat.com/apps/support/errata/
An image file contains an exact copy (or image) of a diskette's contents. Since a diskette contains file system information in addition to the data contained in files, the contents of the image file are not usable until they have been written to a diskette.
To start, you will need a blank, formatted, high-density (1.44MB), 3.5-inch diskette. You will need access to a computer with a 3.5-inch diskette drive. The computer must be able to run either an MS-DOS program or the dd utility found on most Linux-like operating systems.
The images directory on your Red Hat Linux CD-ROM contains the boot images for Red Hat Linux/x86. Once you have selected the proper image (such as boot.img for a CD-ROM-based installation or bootnet.img for a network installation), transfer the image file onto a diskette using one of the following methods.
Using the rawrite Utility
To make a diskette using MS-DOS, use the rawrite utility included on the Red Hat Linux CD-ROM in the dosutils directory. First, label a blank, formatted 3.5-inch 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\boot.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 filename of a diskette image; enter the directory and name of the image you wish to write (for example, ..\images\boot.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. If you need 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[2]. 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. |
