Chapter 4. Installing Red Hat Enterprise Linux 19
HTTP
If you are installing directly from an HTTP (Web) server, use this method. You need a boot CD-
ROM (use the linux askmethod boot option). Refer to Section 4.10 Installing via HTTP, for
HTTP installation instructions.
4.5. Installing from CD-ROM
To install Red Hat Enterprise Linux from a CD-ROM, choose the CD-ROM option and select OK.
When prompted, insert the Red Hat Enterprise Linux CD into your CD-ROM drive (if you did not
boot from the CD). Once the CD is in the CD-ROM drive, select OK, and press [Enter].
Note
The first CD-ROM is required when booting the installation program, and again after subsequent
CD-ROMs have been processed.
The installation program then probes your system and attempts to identify your CD-ROM drive. It
starts by looking for an IDE (also known as an ATAPI) CD-ROM drive. If found, continue to the next
stage of the installation process (refer to Section 4.12 Language Selection).
Note
To abort the installation process at this time, reboot your machine and then eject the boot media.
You can safely cancel the installation at any point before the About to Install screen. Refer to
Section 4.24 Preparing to Install for more information.
If your CD-ROM drive is not detected, and it is a SCSI CD-ROM, the installation program prompts
you to choose a SCSI driver. Choose the driver that most closely resembles your adapter. You may
specify options for the driver if necessary; however, most drivers detect your SCSI adapter automati-
cally.
Tip
A partial list of optional parameters for CD-ROM drives can be found in the Red Hat Enterprise Linux
Reference Guide, in the General Parameters and Modules appendix.
4.5.1. What If the IDE CD-ROM Was Not Found?
If you have an IDE (ATAPI) CD-ROM on an x86, AMD64, or Intel® EM64T system, but the in-
stallation program fails to find your IDE (ATAPI) CD-ROM and asks you what type of CD-ROM
drive you have, try the following boot command. Restart the installation, and at the boot: prompt
enter linux hdX=cdrom. Replace X with one of the following letters, depending on the interface
the unit is connected to, and whether it is configured as master or slave (also known as primary and
secondary):
