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.

apm=allow_ints
This x86 boot command changes how the suspend service is handled (and may be necessary for

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

apm=realmode_power_off
Some BIOSes crash on x86-based systems 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 Win-
dows 95 way.
dd
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 speci-

display=IP:0
