Red Hat Linux 5.2 Installation and Configuration 3

BRIEF SUMMARY OF LINUX STRATEGY FOR COMPAQ PROFESSIONAL

WORKSTATIONS

In 1H99, Compaq began compatibility testing and pursuing certification of select

Professional Workstation models under the Red Hat Linux distribution (versions 5.2 and 6.0).

Compaq is investigating other distributions and certification programs in the future.

Currently, Compaq does not provide driver support for Linux on Professional Workstations.

Customers who wish to run Linux will need to rely on existing driver sets available through

commercial Linux distributions, VARs, or the official Linux Internet web site. The Compaq

warranty does not cover technical support and service for Professional Workstations running

Linux. Compaq, however, will provide telephone-based technical support for Linux-certified

models on a fee basis. Although plans to offer Linux as a preinstalled operating system do

not yet exist, this strategy is subject to change.

4Red Hat Linux 5.2 Installation and Configuration

Overview

This document covers the installation and configuration of Red Hat Linux 5.2 Compaq

Professional Workstations AP and SP models.

All Web URLs and FTP sites listed in this guide are embedded links and permit the reader to

jump directly to those sites using an installed Web browser.

Prepare the Hardware

The IRQ number of the network interface controller (NIC) must be changed before

installation of the operating system or initialization fails. Prior to installation of Linux, run

Setup (F10) and change the IRQ number assigned to the NIC (typically 11) to either IRQ 9 or

10.

Install Red Hat Linux

The Red Hat Linux 5.2 install program includes pre-defined installation classes. Any of the

installation classes are appropriate for the AP200, AP400, and AP500. The Workstation class

is the most appropriate. The Custom installation class is required for the SP700.

Initial Installation Steps

1. Insert the Red Hat Linux 5.2 Operating System CD into the CD-ROM drive and restart

the workstation.

The Red Hat Linux GUI starts and takes the user through each step of the installation

process. Read each screen carefully for instructions and explanations. Use the up/down

arrow keys to access the appropriate selection.

2. Choose a language; this varies from site to site.

3. Choose a keyboard type; this varies from site to site.

4. Choose an Installation method (file source).

Note: This guide assumes a local CD-ROM installation. Alternative installation methods

are discussed in the Red Hat 5.x installation manual.

5. Install Path; choose install or upgrade.

Installation Class; Choose Workstation or Custom for AP200, AP400, AP500; Choose

Red Hat Linux 5.2 Installation and Configuration 5

Note: The AP400 and AP500 SCSI probe automatically finds the NCR 53C8xx PCI adapter.

The SP700 SCSI probe does not identify any SCSI devices so you must answer:

Do you have any SCSI adapters? Yes

When prompted to load a SCSI module: Select NCR 53C8xx PCI

Class-Based Installation Path

The Workstation and Server Installation Path installs a pre-configured disk partitioning

scheme. If the Workstation or Server Installation Path is chosen, the RedHat Linux

Installation program prompts the user twice that disk data will be lost, then creates a new file

system with three or more partitions. After automatically partitioning the drive, the

installation program automatically formats the newly created partitions and proceeds to install

packages. Jump ahead to “Finishing the Installation.”

Important Note: Workstation or Server Installation Path ignores any Compaq System

Partitions! The installation program removes any Linux partitions found on the drive(s) and

recreates a filesystem, then installs the Linux Loader (LILO) into the boot sector of the

primary drive.

Custom Installation Path

The Custom Installation Path gives the user complete control of creating the Linux filesystem

partitions formatting, and software package selection. Users who wish to create custom

filesystem configurations or to preserve a previous configuration should choose Custom

Installation.

Disk Partitioning

The Red Hat Linux GUI offers the user a choice of either the disk partitioning utility, Disk

Druid, or the fdisk utility. Disk Druid displays a table representing the:

•Disk partitions

•Amount of disk used and amount available

•Partition type (Linux Native, Linux Swap, etc.)

•Mount points (i.e. /, /home /usr/local, etc.)

Disk Druid permits the user to add, edit, or delete partitions. In addition, Disk Druid permits

the user to designate certain partitions as “growable,” in which the partition is initially created

as a certain size, but is permitted to “grow” in size as needed.

6Red Hat Linux 5.2 Installation and Configuration

In general, the swapfile partition size should equal the amount of installed memory. A

practical minimum size is 16MB. The maximum swap size is 127MB per swap area.

Multiple swapfile partition may be created.

Package Selection

After formatting the partitions, the user must select which RPM packages to install. If the

unit will connect to an Ethernet network, you must select the package "Networked

Workstation."

Finishing the Installation

Configure Mouse

The RedHat mouseconfig utility probes for a mouse, and typically detects a PS/2-style

mouse; however, the user must designate which mouse type to use:

•Systems with a two-button mouse should Emulate 3 buttons.

•Emulate 3 buttons is not necessary on a 3 or 4 button mouse.

Configure X Windows

If you selected X Windows package, RedHat’s Xconfigurator tool attempts to detect the

installed video board and selects the appropriate X server or presents a list of video boards. If

the list appears, select Unlisted Card, then select VGA16 server, you will have to install the

X86Free update as explained later in this document.

Note: RedHat Linux 5.2 ships with XFree86 version 3.3.2, which includes support for

Matrox Millennium II PCI and AGP. XFree86 3.3.3.1 has recently been released and includes

an Xserver for Matrox Productiva G100 and Millennium G200 and 3Dlabs chipsets (ELSA

and Oxygen GMX).

The information needed to properly configure the monitor should be obtained directly from

the specification sheet in the monitor documentation to ensure the best performance of

XFree86 (see monitor specification table in the Appendix). The information required in this

module is:

•Monitor type - for Compaq monitors, I recommend choosing Custom or Generic

Multisync.

Note: XFree86 3.3.3.1 update adds several Compaq monitor definitions. Choose the

appropriate Compaq Monitor if it is supported by Xconfigurator.

•Vertical (frequency) Range - see your monitor specs

Red Hat Linux 5.2 Installation and Configuration 7

During controller configuration steps:

1. Select Don't Probe

2. Select the correct amount of video RAM,

3. Select No Clockchip option

4. Probe for Clocks screen - select Skip

Network Configuration

If you select Yes when asked to configure the network, Red Hat Linux 5.2 probes and finds

the Intel EtherExpress Pro 100 controller on the AP200, AP400, and AP500. The probe does

not find the network controller on the SP700, and you should choose the Intel EtherExpress

Pro 100 controller.

Timezone Configuration

Linux needs to know the timezone in which the system will be located. The user may select

the appropriate timezone and optionally designate if the system clock is set to Greenwich

Mean Time – Universal Coordinated Time (GMT/UTC).

Printer Configuration

Next, Red Hat Linux prompts to configure a Printer - local or networked. The queue

specifics may be configured and modified as necessary.

Root Password

Next, Red Hat Linux prompts for the creation of a root user password. Type in the desired

password twice, pressing Enter after each entry. Select OK to continue.

Boot Disk Creation

Just as Windows NT prompts to create an Emergency Recovery Diskette, RedHat Linux

prompts the user to create an Emergency Boot Diskette. The Boot Diskette should be

created, especially if the system will dual boot between Linux and Windows NT.

Configure LILO

The last steps in the Red Hat Linux installation process involve configuring LILO, the Linux

boot loader. RedHat’s Class Installation automates placement of LILO in the boot sector of

the primary disk.

8Red Hat Linux 5.2 Installation and Configuration

Note: LILO can boot many non-Linux operating systems if installed in the boot sector of a

drive, HOWEVER LILO CANNOT BOOT WINDOWS NT! Windows NT's boot loader

"owns" the boot sector of the host drive. Therefore, in this step of Red Hat Linux

configuration, LILO must be installed in the Linux root partition if you plan to dual-boot

Linux with Windows NT!

See the section entitled “Dual Booting Windows NT and Red Hat Linux” for discussion on

how to get Linux to boot from the Windows NT Boot Menu; for example,

NT Workstation Version 4.0

NT Workstation Version 4.0 [VGA Mode]

Linux

After selecting the location where LILO will be installed, Red Hat Linux prompts for the

following information:

•Other partitions to add to the LILO menu. DOS, Windows 95, and F10 Diags partition

can be added in this step.

•Optional boot parameters that must be passed to the Linux kernel at bootup. The screen

also shows an option to Use Linear Mode (needed for some SCSI drives). Check this box

if the system has SCSI hard drives.

Installation is Complete

After installing LILO, the Red Hat Linux 5.x installation process is complete, and the script

will end by rebooting the unit. Remove all diskettes and CD-ROMs, allow the system to

restart, and observe the bootup messages to verify that the SCSI driver loads properly and

that all daemons start normally.

Final Configuration and Customization Steps

Installing the XFree86 Updates

The installation of the XFree86 3.3.3.1 update is required for proper operation of X on many

models because of no support for graphic boards in the XFree86 version shipped with the Red

Red Hat Linux 5.2 Installation and Configuration 9

Dual-Booting Windows NT and Red Hat Linux

Several Linux HOWTO’s have been published to document dual-booting Linux with other

operating systems. The following steps outlined in one specific HOWTO have been used

successfully. The steps may be found at:

http://metalab.unc.edu/mdw/HOWTO/mini/Linux+NT-Loader.html

Installation sequence matters.

1. Install the Diagnostics and Setup utilities first, using SmartStart for Workstations,

2. Install Windows NT 4.0 Workstation and the Workstation SSD,

3. Install Linux last.

In section 5 of the HOWTO document, the author indicates that the LILO boot sector must be

copied from the Linux system partition onto diskettes or otherwise moved to the NT partition,

since Windows NT’s NTLDR owns the Master Boot Record.

Unless you created a Linux Boot Diskette, you must boot the system from the Red Hat Linux

Installation diskettes. At the boot prompt, enter rescue and press enter. Continue through the

process of identifying keyboard, PCMCIA support, and SCSI support (pick NCR

53C810/53C820 (Alternate) as before).

The rescue diskettes will leave the user at the command prompt. Enter the commands below

to mount the Linux partition and the floppy assuming /dev/sda4 is your Linux Partition:

[WS]# mount sda4 /mnt

Extract the Linux boot sector as follows (type this command on a single line):

[WS]# dd if=/mnt/dev/sda4 of=/mnt/bootsect.lnx bs=512 count=1

There is something wrong if your bootsect.lnx has more than 512 bytes.

Now, eject the Supplemental Diskette and insert a DOS-formatted diskette. The next step

copies the file bootsect.lnx to the DOS-formatted diskette as this is your method to

transfer files to the Windows NT-NTFS partition. Insert the DOS diskette in place of the

Linux boot diskettes, then you can copy it with:

[WS]# mkdir /floppy

[WS]# mount –t msdos fd0 /floppy

[WS]# cp /mnt/bootsect.lnx /floppy

[WS]#

umount /floppy

Linux SMP Support

See the links referenced in the “Additional Resources” for more specifics. The Linux SMP

FAQ cites the following prerequisites to successfully enable SMP support on Linux:

“How do I make a Linux SMP kernel?”

The SMP FAQ is quoted below:

•Uncomment the SMP=1 line in the main Makefile

(/usr/src/Linux/Makefile).

•Enable "RTC support". Note that inserting RTC support

actually doesn't prevent drift, but … it can prevent lockup

when the clock is read at boot time. A note … says also

that activating the Enhanced RTC is necessary to get the

second CPU working (identified) on some original Intel

Mainboards.

•Do NOT enable APM! APM and SMP are not compatible, and your

system will almost certainly … crash under boot if APM is

enabled.

You must rebuild all your kernel and kernel modules when changing to and from SMP mode.

Remember to make modules and make modules_install.
