The files in this directory are raw disk images.  Some are boot disks
for booting the Red Hat Linux installation program.  Others are driver
disks to support loading the installation program from less common
hardware.

Follow the instructions in the Red Hat Linux Installation Guide,
Chapter 2, section "Making Installation Diskettes" to create the
disks.

The drivers.img driver disk image has been split into several disks
because of the increasing size of the supported modules.

The following boot images images available:

boot.img - boot image for CD and hard drive based install
bootnet.img - boot image for network based install
pcmcia.img - boot image for installing on laptops

The following driver disks are available:
