Bootup Screen

Bootup Screen

Some of the most common options passed to the installer on this screen is
  • linux text
  • linux serial
  • linux rescue
  • linux noprobe
  • linux nousb

Another popular thing to do is to bypass many of the standard questions
  • Get all the way to the graphics screen, except putting in the driver disk, using dhcp
    linux lang=en keymap=us ip=dhcp
  • Get all the way to the graphics screen, except putting in the driver disk, using a static ip
    linux lang=en keymap=us ip= netmask= gateway= dns=

One other interesting option is the display option. It is described below about how to use it. Please note that it only redirects the graphical part of the install, and will not work at all on a text install. One of the reasons someone might want to do this is if you are doing a long install on a machine far away. You could get it started locally, directing it's output to your desktop. Then finish the install from your desktop.

Installation Help

To begin an installation or upgrade with the most common options, simply wait 60 seconds, hit enter, or type 'linux' and then <Enter>.
This is also where you can pass options to the installation program to make it perform differently.
Options should be passed by typing 'linux <option>' and then hitting <Enter> such as
    linux rescue <Enter>

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). It useful because some BIOSes have buggy power management (APM) and tend to crash.


This command makes Red Hat Linux shutdown (power off) the system by default. It 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 argument causes the installation program to prompt you to use a driver diskette.


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 original display. 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.


Comma separated list of nameservers to use for a network installation.


This command performs the same function as the dd command and also prompts you to use a driver diskette during the installation of Red Hat Linux.


This command turns on the following special features:

  • allows partitioning of removable media

  • prompts for driver diskette


Gateway to use for a network installation.


This command disables DMA on all IDE devices and may be useful when having IDE-related problems.


IP to use for a network installation, use 'dhcp' for DHCP.


This command prompts you for ISA device configuration.


Keyboard layout to use. Valid values are those which can be used for the 'keyboard' kickstart command.


This command tells the installer to use a kickstart file, and where to get it from.

  • ks
    Kickstart over NFS.

  • ks=cdrom:
    Kickstart from CDROM

  • ks=nfs:<path>
    Kickstart from NFS.

  • ks=hd:<dev>
    Kickstart via harddrive (dev = 'hda1', for example)

  • ks=file:<path>
    Kickstart from a file (path = 'fd0/ks.cfg')

  • ks=<url>
    Kickstart via HTTP.

  • ks=ftp://<path>
    Kickstart from FTP.

  • ks=http://<path>
    Kickstart from HTTP.


Language to use for the installation. This should be a language which is valid to be used with the 'lang' kickstart command.

linux upgradeany

This command relaxes some of the checks on your /etc/redhat-release file. If your /etc/redhat-release file has been changed from the default, your Red Hat Linux installation may not be found when attempting an upgrade to Red Hat Linux 9.


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 the install source (if an ISO-based method). Verifying that the ISO images are intact before you attempt an installation helps 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 allows you to tell how you want to install, and from where:

  • method=nfs:<path>
    Use <path> for an NFS installation.

  • method=http://<path>
    Use <path> for an HTTP installation

  • method=ftp://<path>
    Use <path> for an FTP installation

  • method=hd://<dev>/<path>
    Use <path> on <dev> for a hard drive installation

  • method=cdrom
    Do a CDROM based installation.


Netmask to use for a network installation.


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 not to use the APIC chip. It may be helpful for some motherboards with a bad APIC (such as the Abit BP6) or with a buggy BIOS.


This command tells the kernel to disable Athlon optimizations. This command may be helpful where Athlon optimizations are found not to work on certain chipsets.


Do not load support for firewire devices


Do not load the VGA16 framebuffer required for doing text-mode installation in some languages


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.


Don't automatically mount any installed Linux partitions in rescue mode.


Do not attempt to load support for parallel ports


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.


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 may cause the system to reboot successfully.


This command runs rescue mode. Refer to the 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 prompts you to insert a floppy diskette containing updates (bug fixes). It is not needed if you are performing a network installation and have already placed the updates image contents in RHupdates/ on the server.
