This appendix discusses additional boot and kernel boot options available for the Red Hat Linux installation program.
To use any of the boot options presented here, type the command you wish to invoke at the installation boot: prompt.
For example:
boot: text

Boot Time Command Arguments
This command asks you to select the installation method you would like to use when booting from the Red Hat Linux CD-ROM.
This command works around a bug commonly encountered in the Intel 440GX chipset BIOS and should only be executed with the installation program kernel.
This command changes how the suspend service is handled (and may be necessary for some laptops).
This command disables APM (Advanced Power Management). This is useful because some BIOSes have buggy power management (APM) and tend to crash.
This command will make Red Hat Linux shutdown (power off) the system by default. This is useful for SMP systems that do not shutdown by default.
Some BIOSes crash 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.
This command will prompt you to use a driver disk during the installation of Red Hat Linux.
This command allows remote display forwarding. In this command, IP should be replaced with the IP address of the system you want the display to appear on.
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 you are running the original display from. Using the command xhost +remotehostname limits access to the remote display terminal and does not allow access from anyone or any system not specifically authorized for remote access.
This command performs the same function as the dd command and will also prompt you to use a driver disk during the installation of Red Hat Linux.
This command will turn on the following special features:
allows partitioning of removable media
prompts for driver disk
This command disables DMA on all IDE devices and may be useful when having IDE-related problems.
This command prompts you for ISA device configuration.
This command forces the graphical (GUI) installation program to run at a lower resolution (640x480).
This command gives you the option of testing the integrity of install source (if an ISO-based method). Verifying that the ISO images are intact before you attempt an installation will help to avoid problems that are often encountered during an installation.
This command allows you to override the amount of memory the kernel detects for the machine. This may be needed for some older systems where the only 16 MB is detected and for some new machines where the video card shares the video memory with the main memory. When executing this command, xxx should be replaced with the amount of memory in megabytes.
This command enables the built-in kernel deadlock detector. This command can be used to debug hard kernel lockups. By executing periodic NMI (Non Maskable Interrupt) interrupts, the kernel can monitor whether any CPU has locked up, and print out debugging messages as needed.
This command tells the kernel to not use the APIC chip. This command may be helpful for some motherboards with a bad APIC (such as the Abit BP6) or with a buggy BIOS.
This command disables hyperthreading (when available in SMP systems).
This command disables self-diagnosis checks performed on the CPU. The kernel enables self-diagnosis on the CPU by default (called Machine Check Exception). On some older Compaq machines, this check is run too often and may need to be disabled.
This command disables automatic mounting of any installed Linux partitions in rescue mode.
This command disables the passing of keyboard and mouse information to stage 2 of the installation program. This is good for testing keyboard and mouse configuration screens during stage 2 of the installation program when performing a network installation.
This command ignores any PCMCIA controllers in system.
This command disables hardware detection and instead prompts the user for hardware information.
This command disables shell access on virtual console 2 during an installation.
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.
This command disables the loading of the usbstorage module in the installation program's loader. It may help with device ordering on SCSI systems.
This 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 will allow the system to reboot.
This command will run rescue mode. Refer to the Official Red Hat Linux Customization Guide for more information about rescue mode.
Tells the installation program which video mode to run. It accepts any standard resolution, such as 640x480, 800x600, 1024x768, and so on.
This command turns on serial console support.
This command skips the ddc monitor probe which causes problems on some systems.
This command disables the graphical installation program and forces the installation program to run in text mode.
This command will prompt you to insert a floppy diskette containing updates (bug fixes). This is not needed if you are performing a network installation and have already placed the updates image contents in RHupdates/ on the server.
