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
information about rescue mode.
resolution=

640x480, 800x600, 1024x768, and so on.

this command turns on serial console support.
text
this command disables the graphical installation program and forces the installation program to
run in text mode.

anaconda installation program. It is not needed if you are performing a network installation and
have already placed the updates image contents in rhupdates/ on the server.
updates=
this command allows you to specify a URL to retrieve updates (bug fixes) for the anaconda
installation program.
