Appendix A: Additional Boot Options
This appendix 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.
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 necessary for some
laptops).
apm=off:
This x86 boot command disables APM (Advanced Power Management). It 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 machine. This
command changes the method of how this is done from the Windows NT way to the Windows 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?ed
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
