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
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 diskette or CD-ROM. You can safely cancel the installation at any point before the About to Install screen. Refer to Section 4.25 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 automatically.
 | 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 or AMD64 system, but the installation 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 the 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):
a — first IDE controller, master
b — first IDE controller, slave
c — second IDE controller, master
d — second IDE controller, slave
If you have a third and/or fourth controller, continue assigning letters in alphabetical order, going from controller to controller, and master to slave.
