While the Red Hat Enterprise Linux installation program is loading, a screen may appear asking you for driver media. The driver media screen is most often seen in the following scenarios:
If you need to perform an installation from a network device
If you need to perform an installation from a PCMCIA device
If you run the installation program by entering linux dd at the installation boot prompt (Itanium users should enter elilo linux dd)
If you run the installation program on a computer which does not have any PCI devices
