Chapter 8. Additional Boot Options

for Intel® and AMD Systems

This appendix discusses additional boot and kernel boot options available for the Red Hat En-

terprise Linux installation program.

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

stallation boot: prompt.

Boot Time Command Arguments

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.

apm=allow_ints

this x86 boot command changes how the suspend service is handled (and may be neces-

sary for some laptops).

apm=off

this x86 boot command disables APM (advanced power management). It is useful because

some BIOSes have buggy power management (APM) and tend to crash.

apm=power_off

this x86 boot command makes Red Hat Enterprise Linux shutdown (power off) the system

by default. It is useful for SMP systems that do not shutdown by default.

apm=realmode_power_off

some BIOSes crash on x86-based systems when trying to shutdown (power off) the ma-

chine. This command changes the method of how this is done from the Windows NT way to

the Windows 95 way.

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
