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 Linux CD ROM.

apic

should only be executed with the installation program kernel.

apm=allow_ints

This command changes how the suspend service is handled (and may be necessary for some

laptops).

apm=off

This command disables APM (Advanced Power Management). This is useful because some

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

apm=power_off

This command will make Red Hat Linux shutdown (power off) the system by default. This is

useful for SMP systems that do not shutdown by default.

apm=realmode_power_off

Some BIOSes crash when trying to shutdown (power off) the machine. This command changes

the method of how this is done from the Windows NT way to the Windows 95 way.

dd

This command will prompt you to use a driver disk during the installation of Red Hat Linux.

display=IP:0

This command allows remote display forwarding. In this command, IP should be replaced with

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

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 you are running the

original display from. Using the command

xhost +remotehostname

limits access to the
