installation program. It can be used to test keyboard and mouse configuration screens
during stage 2 of the installation program when performing a network installation.
nopcmcia

information.
noshell

nousb
this command disables the loading of USB support during the installation. If the installation
program tends to hang early in the process, this command may be helpful.

numa=off
Red Hat Enterprise Linux supports NUMA (non-uniform memory access) on the AMD64
architecture. while all cpus can access all memory even without numa support, the numa
support present in the updated kernel causes memory allocations to favor the cpu on which
they originate as much as possible, thereby minimizing inter-CPU memory traffic. This can
provide significant performance improvements in certain applications. to revert to the
original non-NUMA behavior, specify this boot option.
reboot=b
this x86, AMD64, and Intel® EM64T boot command changes the way the kernel tries to
reboot the machine. If a kernel hang is experienced while the system is shutting down, this
command may cause the system to reboot successfully.
rescue
this command runs rescue mode. Refer to Chapter 27, Basic System Recovery for more
information about rescue mode.
resolution=
tells the installation program which video mode to run. it accepts any standard resolution,
such as 640x480, 800x600, 1024x768, and so on.
