Chapter 8. Additional Boot Options for Intel® and AMD Systems

This section discusses additional boot and kernel boot options available for the Red Hat Enterprise

Linux installation program.

To use any of the boot options presented here, type the command you wish to invoke at the

installation boot: prompt.

Bo o t T ime C o mman d Arg umen t s

askmethod

this command asks you to select the installation method you would like to use when

booting from the Red Hat Enterprise Linux CD-ROM.

apic

this x86 boot command works around a bug commonly encountered in the Intel 440GX

chipset BIOS and should only be executed with the installation program kernel.

this argument causes the installation program to prompt you to use a driver diskette.

dd=url

this argument causes the installation program to prompt you to use a driver image from a

specified HTTP, FTP, or NFS network address.

display=ip:0

this command allows remote display forwarding. In this command, ip should be replaced

with the IP address of the system on which you want the display to appear.

On the system you want the display to appear on, you must execute the command xhost

+remotehostname, where remotehostname is the name of the host from which you are

running the original display. Using the command xhost +remotehostname limits access

to the remote display terminal and does not allow access from anyone or any system not

specifically authorized for remote access.

driverdisk

this command performs the same function as the dd command and also prompts you to use

a driver diskette during the installation of Red Hat Enterprise Linux.

linux upgradeany

this command relaxes some of the checks on your /etc/redhat-release file. If your

/etc/redhat-release file has been changed from the default, your Red Hat Enterprise

Linux installation may not be found when attempting an upgrade to Red Hat Enterprise

Linux 5. Use this option only if your existing Red Hat Enterprise Linux installation was not

detected.
