Installing Red Hat* Enterprise Linux 4*

Intel® Server Board S5000PAL

Note: Refer to Appendix A “Additional Boot Options” for additional boot options not covered in this section.

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

linux text

2)ISO images have an md5sum embedded in them. To test the checksum integrity o f an ISO image, at the installation boot prompt, type:

linux mediacheck

3)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.

4)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.

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

linux console=<device>

6)For text mode installations, use:

linux text console=<device>

Note: In the above command, <device> should be the device you are using (such as ttyS0 or ttyS1). For example, linux text console=ttyS0.

7)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:

linux console=ttyS0 utf8

Kernel Options

1)Options can also be passed to the kernel. For example, to instruct the kernel to use all the RAM in a system with 128 MB of RAM, at the installation boot prompt, enter:

linux mem=128M
