Chapter 4. Installing Red Hat Enterprise Linux Figure 4-16. Boot Loader Installation Caution If you have a RAID card, be aware that some BIOSes do not support booting from the RAID card. In cases such as these, the boot loader should not be installed on the MBR of the RAID array. Rather, the boot loader should be installed on the MBR of the same drive as the partition was created.
Chapter 4. Installing Red Hat Enterprise Linux 4.18.2. Rescue Mode Rescue mode provides the ability to boot a small Red Hat Enterprise Linux environment entirely from a diskette, CD-ROM, or some other boot method instead of the system’s hard drive. There may be times when you are unable to get Red Hat Enterprise Linux running completely enough to access files on your system’s hard drive.
Chapter 4. Installing Red Hat Enterprise Linux 4.18.4. SMP Motherboards, GRUB, and LILO This section is specific to SMP motherboards only. SMP, short for Symmetric Multiprocessing, is a computer architecture providing fast performance by making multiple CPUs available to complete individual processes simultaneously (multiprocessing).

Appendix A. Upgrading Your Current System This appendix walks you through a typical Red Hat Enterprise Linux 3 upgrade. Note If you currently use Red Hat Enterprise Linux 2.1 on an x86 system, you can perform an upgrade. Although upgrades are supported by the Red Hat Enterprise Linux family on x86 processors, you are likely to have a more consistent experience by backing up your data and then installing this release of Red Hat Enterprise Linux over your previous Red Hat Enterprise Linux installation.
Note If the contents of your file have been changed from the default, your Red Hat /etc/redhat-release Enterprise Linux installation may not be found when attempting an upgrade to Red Hat Enterprise Linux 3. You can relax some of the checks against this file by booting with the following boot command:...

Appendix D. An Introduction to Disk Partitions D.1.2. Partitions: Turning One Drive Into Many As disk drive capacities soared, some people began to wonder if having all of that formatted space in one big chunk was such a great idea. This line of thinking was driven by several issues, some philosophical, some technical.
Appendix D. An Introduction to Disk Partitions Figure D-6. Disk Drive With Single Partition In many cases, there is only a single partition spanning the entire disk, essentially duplicating the method used before partitions. The partition table has only one entry used, and it points to the start of the partition.
Appendix D. An Introduction to Disk Partitions continued to grow, it became more and more likely that a person could configure four reasonably- sized partitions and still have disk space left over. There needed to be some way of creating more partitions.

Appendix D. An Introduction to Disk Partitions Linux native Figure D-8. Disk Drive with Unpartitioned Free Space In Figure D-8, 1 represents an undefined partition with unallocated space and 2 represents a defined partition with allocated space. If you think about it, an unused hard disk also falls into this category. The only difference is that all the space is not part of any defined partition.

Appendix D. An Introduction to Disk Partitions plete backup is necessary. For your own sake, make two backups, use verification (if available in your backup software), and try to read data from your backup before you delete the partition. Caution If there was an operating system of some type installed on that partition, it needs to be rein- stalled as well.
Page 100
Appendix D. An Introduction to Disk Partitions Figure D-11. Disk Drive Being Compressed In Figure D-11, 1 represents before and 2 represents after. This step is crucial. Without it, the location of your data could prevent the partition from being resized to the extent desired.
Appendix D. An Introduction to Disk Partitions Note The following information is specific to x86-based computers only. As a convenience to our customers, we provide the utility. This is a freely available program parted that can resize partitions. If you decide to repartition your hard drive with , it is important that you be familiar with parted disk storage and that you perform a backup of your computer data.
Appendix D. An Introduction to Disk Partitions The final number denotes the partition. The first four (primary or extended) partitions are num- bered through . Logical partitions start at . So, for example, is the third primary /dev/hda3 or extended partition on the first IDE hard disk, and is the second logical partition /dev/sdb6 on the second SCSI hard disk.
Appendix D. An Introduction to Disk Partitions Keeping this in mind, we recommend that, unless you have a reason for doing otherwise, you should at least create the following partitions: (or a partition for Itanium systems)„ swap /boot/ /boot/efi/ /boot/efi/, and (root).

Appendix D. An Introduction to Disk Partitions On First IDE or First SCSI Drive If you have one IDE (or EIDE) drive and one or more SCSI drives, must be located /boot/ either on the IDE drive or the SCSI drive at ID 0. No other SCSI IDs will work. On First Two SCSI Drives If you have only SCSI hard drives, must be located on a drive at ID 0 or ID 1.
Appendix E. Driver Media E.1. Why Do I Need Driver Media? While the Red Hat Enterprise Linux installation program is loading, a screen may appear asking you for driver media. The driver media screen is most often seen in the following scenarios: If you need to perform an installation from a network device •...
Another option for finding specialized driver information is on Red Hat’s website at http://www.redhat.com/support/errata/ under the section called Bug Fixes. Occasionally, popular hardware may be made available after a release of Red Hat Enterprise Linux that does not work with drivers already in the installation program or included on the driver images on the Red Hat Enterprise Linux CD #1.
Appendix F. Additional Boot Options This appendix discusses additional boot and kernel boot options available for the Red Hat Enterprise Linux installation program. To use any of the boot options presented here, type the command you wish to invoke at the installation prompt.
