enables self-diagnosis on the CPU by default (called machine check exception). Early Compaq Pentium systems may need this option as they do not support processor error checking
correctly. A few other laptops, notably those using the Radeon IGP chipset, may also need
this option.
nonet
this command disables network hardware probing.
nopass
this command disables the passing of keyboard and mouse information to stage 2 of the 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
this command ignores any PCMCIA controllers in system.
noprobe
this command disables hardware detection and instead prompts the user for hardware information.
noshell
this command disables shell access on virtual console 2 during an installation.
nostorage
this command disables probing for SCSI and RAID storage hardware.
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.
nousbstorage
this command disables the loading of the usbstorage module in the installation program's
loader. It may help with device ordering on SCSI systems.
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 26, Basic System Recovery for more information about rescue mode.
resolution=
tells the installation program which video mode to run. it accepts any standard resolution,
