What page isn't available? "boot.img" which you need will be on your cd's. here's what that link said about it:
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] 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.
Using the dd Command
To make a diskette under Linux (or any other Linux-like operating system), you must have permission to write to the device representing a 3.5-inch diskette drive (known as /dev/fd0 under Linux).
First, label a blank, formatted diskette appropriately (such as "Boot Disk" or "Updates Disk"). Insert it into the diskette drive (but do not mount[3] the diskette). After mounting the Red Hat Linux CD-ROM, change to the directory containing the desired image file, and use the following command (changing the name of the image file and diskette device as appropriate):
# dd if=boot.img of=/dev/fd0 bs=1440k
To make another diskette, label that diskette, and run dd again, specifying the appropriate image file.
