Installation guide

For Itanium users:

To pass options to the boot loader on an Itanium system, enter the following at the EFI Shell prompt:

elilo linux option

For x86, AMD64, and Intel® 64 users:

To pass options to the boot loader on an x86, AMD 64, or Intel® 64 system, use the instructions as

provided in the boot loader option samples below.

Note

Refer to Chapter 8, Additional Boot Options for Intel® and AMD Systems for additional boot

options not covered in this section.

To perform a text mode installation, at the installation boot prompt, type:

linux text

ISO images have an md5sum embedded in them. To test the checksum integrity of an ISO image,

at the installation boot prompt, type:

linux mediacheck

The installation program prompts you to insert a CD or select an ISO image to test, and select OK

to perform the checksum operation. This checksum operation can be performed on any Red Hat

Enterprise Linux CD and does not have to be performed in a specific order (for example, CD #1

does not have to be the first CD you verify). It is strongly recommended to perform this operation

on any Red Hat Enterprise Linux CD that was created from downloaded ISO images. This

command works with the CD, DVD, hard drive ISO, and NFS ISO installation methods.

Also in the images/ directory is the boot.iso file. This file is an ISO image than can be used to

boot the installation program. To use the boot.iso, your computer must be able to boot from its

CD-ROM drive, and its BIOS settings must be configured to do so. You must then burn the

boot.iso file onto a recordable/rewriteable CD-ROM.

If you need to perform the installation in serial mode, type the following command:

linux console=<device>

For text mode installations, use:

linux text console=<device>

In the above command, <device> should be the device you are using (such as ttyS0 or ttyS1). For

example, linux text console=ttyS0.

Text mode installations using a serial terminal work best when the terminal supports UTF-8. Under

UNIX and Linux, Kermit supports UTF-8. For Windows, Kermit '95 works well. Non-UTF-8 capable

terminals works as long as only English is used during the installation process. An enhanced

serial display can be used by passing the utf8 command as a boot-time option to the

installation program. For example:
