Installing Red Hat* Enterprise Linux 4*

Intel® Server Board S5000PAL

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.

driverdisk:

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 Enterprise Linux.

ide=nodma:

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

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 Enterprise Linux installation may not be found when attempting an upgrade to Red Hat Enterprise Linux 4. Use this option only if your existing Red Hat Enterprise Linux installation was not detected.

mediacheck:

This command gives you the option of testing the integrity of the install source (if an ISO-based method). This command works with the CD, DVD, hard drive ISO, and NFS ISO installation methods. Verifying that the ISO images are intact before you attempt an installation helps to avoid problems that are often encountered during an installation.

mem=xxxM:

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 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,

xxxshould be replaced with the amount of memory in megabytes. nmi_watchdog=1:

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.

noapic:

This x86 boot 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. Systems based on the NVIDIA nForce3 chipset (such as the ASUS SK8N) have been known to hang during IDE detection at boot time, or display other interrupt-delivery issues.

noht:

This x86 boot command disables hyperthreading.
