Linux Installation and Configuration Guide for AlphaServer 29

In the output above, the first line shows that DKA0 is a hard disk, DQA0 is a CD-ROM, and

DVA0 is a floppy drive.

Also useful for inspecting the computer configuration is the "show config" command, as shown

here:

P00>>>show config | more

Configure the system SRM parameters to boot from your installation device. The commands for

configuring to boot from the CDROM device are shown here:

P00>>>set bootdef_dev dqa0

P00>>>set boot_file

P00>>>set boot_osflags

P00>>>show boot*

boot_dev dqa0.0.0.105.0

boot_file

boot_osflags

boot_reset OFF

bootdef_dev dqa0.0.0.105.0

booted_dev

booted_file

booted_osflags

Insert the Suse 6.3 CD into the drive.

Boot the system using the "boot –flags 0" command. The result should be that the system boots

from the CDROM.

If during this process you encounter a problem, such as due to a typographic error in the setting of

the SRM parameters, you will probably be stopped with an "aboot>" prompt. The best way to

deal with this situation is to reset the system using the reset button on the front panel. Then using

the SRM commands, correct the mistake, and repeat the "boot" process.

Software Installation

SuSE’s installation program is flexible. While it allows for autodetection of devices and autoload

of device drivers, it allows you to override the automatically configured parameters. Compaq’s

testing this Solutions Guide was performed using SuSE Version 6.3.

The software installation process requires that the system be rebooted at two critical places in the

process. The first time is just after completing the partitioning of the disk, and the second happens

automatically after all of the software components are installed on the disk. Be certain not to skip

the reboot after the disk partition process is completed.

Disk Partitioning

In preparation to partition your disk, you should boot your AlphaServer via the BOOT CDROM

and following the process for selecting a language, display color, keyboard type, and installation

media. At this stage, you should select the "Install From Scratch" menu option, and proceed to the

window titled "Partition Hard Drives". At this point, press the ALT+F2 keys, which will change

the display to show a shell-command prompt. At this prompt, type the command "fdisk" followed

by the enter key.

The process of partitioning your boot disk for Linux on your AlphaServer can be somewhat

involved. This section provides an example of how perform the partitioning process using fdisk.

Note, the partition recommendations used in steps 14-27 are based on a RZ1DD-AA disk

geometry. If your disk has a different geometry you will need to use different starting/ending

cylinder numbers for each partition. The correct starting/ending cylinder numbers can be

1 2 ... 24 25 26 27 28 29 30 31 32 33 34 ... 55 56
