Pre-Installation
Creating The BOOT Floppy
Before you can begin to install the Linux software on your AlphaServer or AlphaStation, you will need to create a BOOT floppy. This floppy contains the information required to initiate the installation of Linux. The process varies depending upon what software distribution you are using.
An important note: Our experience has shown that the vendor supplied floppy images sometimes do not work properly. You are therefore encouraged to create your own BOOT floppy using the images available over the Internet, as described in the sections that follow.
Creating floppies using a MS/Windows system
To create the BOOT floppy, you will need to make use of a PC, which has Internet access. The instructions below detail the process:
1. Create a directory on the PC into which you will copy files for Linux, for example \Linux.
2. Connect to the URL ftp://ftp.digital.com/pub/DEC/Linux-Alpha/Images/ which is a directory containing the boot floppy image files.
3. Copy the generic-up.2.2.12.img file to your PC.
4. Rename the file to generic.img (DOS has an 8.3 file name limitation)
5. Insert the Linux CD-ROM into the PC.
6. Copy the file "\dosutils\rawrite.exe" from the CD-ROM to the \Linux directory on the PC.
7. Insert a blank, formatted floppy into the PC.
8. Run the following command from the DOS command shell:
C:\Linux> rawrite Enter source file name: generic.img Enter destination drive: a
Label this floppy "AlphaServer Linux BOOT Floppy".
With this floppy in hand, you are now prepared to begin the installation process on your AlphaServer or AlphaStation.
Creating floppies using an Unix system
To create the BOOT floppy, you will need to make use of a computer, which has Internet access. The instructions below detail the process. Note that depending upon what version of unix and vendor computer you are using to perform this process, some minor variations in the process may be required. The exact commands shown here are for Digital Unix, and should be similar to most other popular unix systems.
1. Copy the generic kernel images from the Internet to your computer:
ECG513/0100
$ mkdir /var/tmp/Linux
Linux Installation and Configuration Guide for AlphaServer 11
$ cd /var/tmp/Linux $ ftp ftp.digital.com login: ftp Password: user@ ftp> bin ftp> cd /pub/DEC/Linux-Alpha/Images/ ftp> get generic-up-2.2.12.img ftp> quit
2. Insert a blank, formatted floppy into the computer, and copy the BOOT kernel to it:
$ dd if=generic-up-2.2.12.img of=/dev/fd0
With this floppy in hand, you are now prepared to begin the installation process on your AlphaServer or AlphaStation.
Firmware Inspection and Upgrade
After powering up your AlphaServer or AlphaStation computer, type the command "show version". Check that the version string printed is "V5.4-2 May 19 1999 14:25:16" or newer, and that the first letter of the version string is a "V". If this is not the case, you should upgrade your firmware. Instructions on how to do this can be found at
http://ftp.digital.com/pub/Digital/Alpha/firmware/ along with the latest firmware images.
System Resource Manager Configuration
There are several pieces of information that you need to configure in the SRM subsystem, as well as device identifiers that you should make note of, prior to beginning the installation process. The steps that follow take you through that process.
1. Power up your system. After several diagnostics are completed, you will be presented an SRM prompt ">>>", as shown here:
1024 Meg of system memory probing hose 0, PCI probing PCI-to-ISA bridge, bus 1 probing PCI-to-PCI bridge, bus 2 probing PCI-to-PCI bridge, bus 3 bus 0, slot 9 -- ewa -- DE500-BA Network Controller bus 0, slot 11 -- ewb -- DE500-BA Network Controller bus 0, slot 13 -- dqa -- Acer Labs M1543C IDE bus 0, slot 13 -- dqb -- Acer Labs M1543C IDE bus 0, slot 14 -- vga -- ELSA GLoria Synergy bus 2, slot 4 -- eia -- Intel 82558 Ethernet bus 2, slot 5 -- eib -- Intel 82558 Ethernet bus 2, slot 6 -- eic -- Intel 82558 Ethernet bus 2, slot 7 -- eid -- Intel 82558 Ethernet bus 3, slot 0 -- pka -- NCR 53C875 bus 3, slot 1 -- pkb -- NCR 53C875 bus 3, slot 2 -- ewc -- DE500-AA Network Controller System Temperature is 31 degrees C
AlphaServer DS 10 466 MHz Console V5.4-2, May 19 1999 14:25:16 >>>
2. Determine what devices your system has installed. In particular you will need to note your
ECG513/0100
installation device (a floppy and/or CD-ROM), and your target disk drive. Entering the command "show devices" as shown below will print out the information about your system:
>>>show device dka0.0.0.3000.0 DKA0 RZ1CF-CF 1614
Linux Installation and Configuration Guide for AlphaServer 12
dka100.1.0.3000.0 DKA100 RZ1CF-CF 1614 dka200.2.0.3000.0 DKA200 COMPAQ BB00911CA0 3B05 dka300.3.0.3000.0 DKA300 COMPAQ BB00911CA0 3B05 dqa0.0.0.13.0 DQA0 TOSHIBA CD-ROM XM-6302B 1017 dva0.0.0.0.0 DVA0 eia0.0.0.2004.0 EIA0 00-50-8B-6F-62-AA eib0.0.0.2005.0 EIB0 00-50-8B-6F-62-AB eic0.0.0.2006.0 EIC0 00-50-8B-6F-38-84 eid0.0.0.2007.0 EID0 00-50-8B-6F-38-85 ewa0.0.0.9.0 EWA0 08-00-2B-86-1F-64 ewb0.0.0.11.0 EWB0 08-00-2B-86-1F-63 ewc0.0.0.3002.0 EWC0 00-06-2B-00-0A-5C pka0.7.0.3000.0 PKA0 SCSI Bus ID 7 pkb0.7.0.3001.0 PKB0 SCSI Bus ID 7
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:
>>>show config | more
3. Configure the system SRM parameters to boot from your installation device. A table providing cross-referenced device names is located in Appendix C, for your convenience. Example commands for configuring to boot from the floppy device are shown here:
>>>set bootdef_dev dva0 >>>set boot_file vmlinux.gz >>>set boot_osflags "root=/dev/hda" >>>show boot* boot_dev dva0.0.0.0.0 boot_file vmlinux.gz boot_osflags root=/dev/hda boot_reset OFF bootdef_dev dva0.0.0.0.0 booted_dev booted_file booted_osflags
4. Insert the boot floppy into the drive.
5. Boot the system using the "boot" command. The result should be that the system boots from
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
The Red Hat version used in the testing for this guide has a simple installation program. Most of the devices available with the AlphaServers can be correctly autodetected by Red Hat. Testing for this Solutions Guide was performed using Red Hat Linux version 6.0.
During the boot process, you may see messages about "IDE STO" errors. These can be safely ignored.

the floppy.
Linux Installation and Configuration Guide for AlphaServer 13
When configuring "Timezones", do not select "Hardware clock set to GMT", nor "Startup through ARC console". Instead select "EST" for the timezone, or the value that is appropriate for your location.
Disk Partitioning
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 computed by using these size recommendations and the number of bytes/cylinder for the disk that you are using (this figure is reported by fdisk). The disk used for this example is a 4.3GB drive (DS-RZ1CF) which fdisk shows as having 1023 cylinders:
4 partitions: # size offset fstype [fsize bsize cpg] a: 16368 0 boot # (Cyl. 1 - 2) b: 212784 16368 ext2 # (Cyl. 3 - 28) c: 4272048 229152 swap # (Cyl. 29 - 550) d: 3871032 4501200 ext2 # (Cyl. 551 - 1023)
We strongly recommend the following multi-partition layout: A boot partition – A boot partition is used to reserved the first 2 cylinders (1-2) to write the
bootloader in order to boot the disk from SRM. A root partition – The root partition is where the / (root directory) resides. Always starts at
cylinder 3. We recommend creating a root partition of 300Mb minimum and 900Mb maximum. A swap partition – A swap partition is used to support virtual memory. We commend creating a
swap partition of 2 times the computer RAM. A /usr partition – The /usr partition is where the software of the system resides. This partition
should use all of the space left on the hard drive. To perform the partitioning operation on the disk, when prompted, follow these steps:
1. Arrow to the drive you will be installing the software to and press the ENTER key. You will now be in the fdisk command line
2. Type “m” for help.
3. Type “p” to print the partition table.
4. If there is partition information already configured for the disk, you will need to delete it using the “d” option. Please be sure that you want to zero out this drive. All data will be lost on the drive doing this.
5. Type “b” to edit the BSD disklabel.
6. If you completed the last step correctly, you should see the following: “/tmp/sda contains no disklabel. Do you want to create a disklabel? (y/n)” – Answer Y.
7. Type “m” for more help.
8. Type “p” to print the partition table. You should see a “c” partition that takes up the whole
9. Type “d” to delete a BSD partition
10. Type “c” to delete the c partition

disk. This will have to be removed to install Linux correctly
Linux Installation and Configuration Guide for AlphaServer 14
11. Type “p” to print the partition table and verify no partitions exist
12. Type “n” to add a new BSD partition – the boot partition in this case
13. Type “a” for partition a.
14. First cylinder: Type “1”.
15. Last cylinder: Type “2”.
16. Type “n” to add a new BSD partition – the / (root) partition in this case.
17. Type “b” for partition b.
18. First cylinder: Type “3”.
19. Last cylinder: Type “28”.
20. Type “n” to add a new BSD partition – the swap partition in this case.
21. Type “c” for partition c.
22. First cylinder: Type “29”.
23. Last cylinder: Type “550”.
24. Type “n” to add a new BSD partition – the /usr partition in this case.
25. Type “d” for partition d.
26. First cylinder: Type “551”.
27. Last cylinder: Type “1023” ; last cylinder - one. Do NOT accept the program generated default of "1024" here, because of possible disk corruption.
28. Type “p” to print the partition table. You should notice that the fstype is set to unused for each of the partitions. This will have to be changed via “toggle” – see next step.
29. Type “t” to change the partitions filesystem id.
30. Type “a” for partition a – boot partitions use a “boot” code.
31. Type “L” to list the codes you can use.
32. Enter “d” for boot type.
33. Type “t” to change the partitions filesystem id.
34. Type “b” for partition b – / (root) partitions use a “ext2” code.
35. Enter “8” for ext2 type.
36. Type “t” to change the partitions filesystem id.
37. Type “c” for partition c – swap partitions use a “swap” code.
38. Enter “1” for swap type.
39. Type “t” to change the partitions filesystem id.
40. Type “d” for partition d – /usr partitions use a “ext2” code.
41. Enter “8” for ext2 type.
42. Type “p” to print the partition table – Please verify all your settings.
43. Type “w” to write the disklabel to the disk.

Post-Installation
System Resource Manager Configuration
After the software has been loaded to the disk, the system will attempt to reboot. Before it begins the bootup process, press the front panel reset button. This will stop the bootup process, and
allow you to make the final configuration changes to be able to boot directly from the disk, instead of the floppy or CD-ROM. You should now be at the SRM prompt, ">>>". Enter the following commands to finalize the configuration.
You need to enter these commands, such that the drive reference on the second line needs to refer to the drive which you installed to:
>>>set boot_file 2/boot/vmlinux.gz >>>set bootdef_dev dka0
(or whatever device you installed on. It could also be dqa0 for an IDE drive. See Appendix C for further information on systems with IDE controllers.)
>>>set boot_osflags "root=/dev/sda2" >>>boot dva0 -fi vmlinux.gz
Note - When the system boots, you may see a series of warnings similar to the following: system.map - incorrect version This warning indicates that the kernel version that you installed (i.e. the latest version that you
copied from Compaq's ftp site) was not built at the same time as the rest of the kernel. This will not impact your use of Linux in any way. This warning can be eliminated by installing the kernel sources, all currently recommended patches and rebuilding the kernel.
Once the system is up, login and do the following:
1. Type: swriteboot –f1 /dev/TdZ /boot/bootlx (where T is the type of drive, s for SCSI or h for IDE; and Z is the letter of the drive you are booting; ex: dqa0=hda, dka0=sda).
2. Mount the floppy disk to copy the kernel from the floppy to the /boot/ directory on the system disk. Type: mount /dev/fd0 /mnt/floppy
3. Now go to the /boot directory. Type: cd /boot
4. Copy the kernel. Type: cp /mnt/floppy/vmlinux.gz .
5. Unmount the floppy. Type: umount /dev/fd0
6. Reboot the system. Type: shutdown -h now
The system may or may not hang here. This is a known issue and is being worked on. Please reset or power cycled the system to continue with installation.
At the SRM prompt, you can now boot directly from the hard drive.

Linux Installation and Configuration Guide for AlphaServer 16
SuSE Version 6.1 Distribution
Pre-Installation
Creating The BOOT and RAMDISK Floppies
Before you can begin to install the Linux software on your AlphaServer, you will need to create a BOOT floppy and RAMDISK. These floppies contain the information required to initiate the installation of Linux. The process varies depending upon what software distribution you are using.
Creating floppies using a MS/Windows system
To create the BOOT and RAMDISK floppies, you will need to make use of a PC, which has Internet access. The instructions below detail the process:
1. Create a directory on the PC into which you will copy files for Linux, for example \Linux.
2. Insert the Linux CD-ROM into the PC.
3. Copy the file ftp://tsx-11.mit.edu/pub/linux/dos_utils/rawrite.exe to "\Linux\rawrite.exe" on the PC. This utility is required to build the floppies.
4. Copy the file "aboot_dualncr-qlogic" from ftp://ftp.digital.com/pub/DEC/Linux­Alpha/Images/ to the \Linux directory on the PC and rename the file to aboot.
5. Copy the file "\disks\install" from the CD-ROM to the \Linux directory on the PC.
6. Insert a blank, formatted floppy into the PC.
7. Run the following command from the DOS command shell:
C:\Linux> rawrite Enter source file name: aboot Enter destination drive: a
Label this floppy "AlphaServer Linux BOOT Floppy".
8. Run the following command from the DOS command shell:
C:\Linux> rawrite Enter source file name: install Enter destination drive: a
9. Label this floppy "AlphaServer Linux RAMDISK Floppy".
With those two floppies in hand, you are now prepared to begin the installation process on your AlphaServer.
Creating floppies using an UNIX system
To create the BOOT and RAMDISK floppies, you will need to make use of a computer, which has Internet access. The instructions below detail the process. Note that depending upon what version of unix and vendor computer you are using to perform this process, some minor variations in the process may be required. The exact commands shown here are for Digital UNIX, and should be similar to most other popular UNIX systems.
1. Insert the Linux CD-ROM into the computer, and mount it:
ECG513/0100
$ mount /cdrom
Linux Installation and Configuration Guide for AlphaServer 17
2. Insert a blank, formatted floppy into the computer, and copy the BOOT kernel to it:
$ dd if=/cdrom/disks/aboot of=/dev/fd0
3. Insert a blank, formatted floppy into the computer, and copy the RAMDISK to it:
$ dd if=/cdrom/disks/install of=/dev/fd0
With those two floppies in hand, and the CD-ROM removed from the computer, you are now prepared to begin the installation process on your AlphaServer.
Firmware Inspection and Upgrade
After powering up your AlphaServer computer, type the command "show version". Check that the version string printed is "V5.4-2 May 19 1999 14:25:16" or newer, and that the first letter of the version string is a "V". If this is not the case, you should upgrade your firmware. Instructions on how to do this can be found at http://ftp.digital.com/pub/Digital/Alpha/firmware/ along with the latest firmware images.
System Resource Manager Configuration
There are several pieces of information that you need to configure in the SRM subsystem, as well as device identifiers that you should make note of, prior to beginning the installation process. The steps that follow take you through that process.
1. Power up your system. After several diagnostics are completed, you will be presented an SRM prompt ">>>", as shown here:
1024 Meg of system memory probing hose 0, PCI probing PCI-to-ISA bridge, bus 1 probing PCI-to-PCI bridge, bus 2 probing PCI-to-PCI bridge, bus 3 bus 0, slot 9 -- ewa -- DE500-BA Network Controller bus 0, slot 11 -- ewb -- DE500-BA Network Controller bus 0, slot 13 -- dqa -- Acer Labs M1543C IDE bus 0, slot 13 -- dqb -- Acer Labs M1543C IDE bus 0, slot 14 -- vga -- ELSA GLoria Synergy bus 2, slot 4 -- eia -- Intel 82558 Ethernet bus 2, slot 5 -- eib -- Intel 82558 Ethernet bus 2, slot 6 -- eic -- Intel 82558 Ethernet bus 2, slot 7 -- eid -- Intel 82558 Ethernet bus 3, slot 0 -- pka -- NCR 53C875 bus 3, slot 1 -- pkb -- NCR 53C875 bus 3, slot 2 -- ewc -- DE500-AA Network Controller System Temperature is 31 degrees C
AlphaServer DS 10 466 MHz Console V5.4-2, May 19 1999 14:25:16 >>>
2. Determine what devices your system has installed. In particular you will need to note your installation device (a floppy and/or CD-ROM), and your target disk drive. Entering the command "show devices" as shown below will print out the information about your system:
>>>show device dka0.0.0.3000.0 DKA0 RZ1CF-CF 1614 dka100.1.0.3000.0 DKA100 RZ1CF-CF 1614 dka200.2.0.3000.0 DKA200 COMPAQ BB00911CA0 3B05 dka300.3.0.3000.0 DKA300 COMPAQ BB00911CA0 3B05 dqa0.0.0.13.0 DQA0 TOSHIBA CD-ROM XM-6302B 1017 dva0.0.0.0.0 DVA0 eia0.0.0.2004.0 EIA0 00-50-8B-6F-62-AA eib0.0.0.2005.0 EIB0 00-50-8B-6F-62-AB eic0.0.0.2006.0 EIC0 00-50-8B-6F-38-84

Linux Installation and Configuration Guide for AlphaServer 18
eid0.0.0.2007.0 EID0 00-50-8B-6F-38-85 ewa0.0.0.9.0 EWA0 08-00-2B-86-1F-64 ewb0.0.0.11.0 EWB0 08-00-2B-86-1F-63 ewc0.0.0.3002.0 EWC0 00-06-2B-00-0A-5C pka0.7.0.3000.0 PKA0 SCSI Bus ID 7 pkb0.7.0.3001.0 PKB0 SCSI Bus ID 7
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:
>>>show config | more
3. Configure the system SRM parameters to boot from your installation device. A table providing cross referenced device names is located in Appendix C, for your convenience. Example commands for configuring to boot from the floppy device are shown here:
>>>set bootdef_dev dva0 >>>set boot_file vmlinux.gz >>>set boot_osflags "root=/dev/fd0 load_ramdisk=1" >>>show boot* boot_dev dva0.0.0.0.0 boot_file vmlinux.gz boot_osflags root=/dev/fd0 load_ramdisk=1 boot_reset OFF bootdef_dev dva0.0.0.0.0 booted_dev booted_file booted_osflags
4. Insert the boot floppy into the drive.
5. Boot the system using the "boot" command. The result should be that the system boots from the floppy. You will eventually be prompted to replace the BOOT floppy with the RAMDISK floppy.
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 6.1.
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 floppy 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
ECG513/0100
Linux Installation and Configuration Guide for AlphaServer 19
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 computed by using these size recommendations and the number of bytes/cylinder for the disk that you are using (this figure is reported by fdisk). The disk used for this example is a 4.3GB drive (DS-RZ1CF) which fdisk shows as having 1023 cylinders:
4 partitions: # size offset fstype [fsize bsize cpg] a: 16368 0 boot # (Cyl. 1 - 2) b: 212784 16368 ext2 # (Cyl. 3 - 28) c: 4272048 229152 swap # (Cyl. 29 - 550) d: 3871032 4501200 ext2 # (Cyl. 551 - 1023)
We strongly recommend the following multi-partition layout: A boot partition – A boot partition is used to reserved the first 2 cylinders (1-2) to write the
bootloader in order to boot the disk from SRM. A root partition – The root partition is where the / (root directory) resides. Always starts at
cylinder 3. We recommend creating a root partition of 300Mb minimum and 900Mb maximum. A swap partition – A swap partition is used to support virtual memory. We commend creating a
swap partition of 2 times the computer RAM. A /usr partition – The /usr partition is where the software of the system resides. This partition
should use all of the space left on the hard drive. To perform the partitioning operation on the disk, when prompted, follow these steps:
1. Now you are at the fdisk command line
2. Type “m” for help.
3. Type “p” to print the partition table.
4. If there is partition information already configured for the disk, you will need to delete it using the “d” option. Please be sure that you want to zero out this drive. All data will be lost on the drive doing this.
5. Type “b” to edit the BSD disklabel.
6. If you completed the last step correctly, you should see the following: “/tmp/sda contains no disklabel. Do you want to create a disklabel? (y/n)” – Answer Y.
7. Type “m” for more help.
8. Type “p” to print the partition table. You should see a “c” partition that takes up the whole

12. Type “n” to add a new BSD partition – the boot partition in this case
13. Type “a” for partition a.
14. First cylinder: Type “1”.
15. Last cylinder: Type “2”.
16. Type “n” to add a new BSD partition – the / (root) partition in this case.
17. Type “b” for partition b.
18. First cylinder: Type “3”.
19. Last cylinder: Type “28”.
20. Type “n” to add a new BSD partition – the swap partition in this case.
21. Type “c” for partition c.
22. First cylinder: Type “29”.
23. Last cylinder: Type “550”.
24. Type “n” to add a new BSD partition – the /usr partition in this case.
25. Type “d” for partition d.
26. First cylinder: Type “551”.
27. Last cylinder: Type “1023” ; last cylinder - one. Do NOT accept the program generated default of "1024" here, because of possible disk corruption.
28. Type “p” to print the partition table. You should notice that the fstype is set to unused for each of the partitions. This will have to be changed via “toggle” – see next step.
29. Type “t” to change the partitions filesystem id.
30. Type “a” for partition a – boot partitions use a “boot” code.
31. Type “L” to list the codes you can use.
32. Enter “d” for boot type.
33. Type “t” to change the partitions filesystem id.
34. Type “b” for partition b – / (root) partitions use a “ext2” code.
35. Enter “8” for ext2 type.
36. Type “t” to change the partitions filesystem id.
37. Type “c” for partition c – swap partitions use a “swap” code.
38. Enter “1” for swap type.
39. Type “t” to change the partitions filesystem id.
40. Type “d” for partition d – /usr partitions use a “ext2” code.
41. Enter “8” for ext2 type.
42. Type “p” to print the partition table – Please verify all your settings.
43. Type “w” to write the disklabel to the disk.
44. Type “q” to quit.

Linux Installation and Configuration Guide for AlphaServer 21
For further information on creating partitions please refer to the Installation Guide provided by the software distribution vendor.
At this point, the partitions have been created, and the system must be rebooted. You can reboot by either pressing the RESET or POWER buttons on the front of the AlphaServer system. Once the system returns to the SRM prompt, follow the preceeding instructions to return to the "Partition Hard Drives" window. Select the "Do Not Partition" option at this screen.
You will now be presented a window that allows you to select and format the disk for the software to be installed, entitled "Creating Filesystems". You should use the F4 key to define the mount point of "/" for sda2 and “/usr” for sda4. Use the F6 key to select the "Normal" formatting of the drive for both partitions. Once those steps are complete, press enter to continue.
When the window "Change/Create Configuration" is presented we recommend that you make certain to select the "aboot" package from the "a: Linux Base System" group, and the "xglint" package from the "xsrv: X Server Software" group. Ensure that you depress the F10 key after each selection to add it to the installation. If you forget to select these packages, you will not be able to boot directly from the hard drive, nor be able to run the X Window System software. Once these are selected, and you have selected any other software options that you require, begin the installation. If you encounter a message indicating that the xglint software depends upon other packages, select "Continue", which will ignore that situation.

System Resource Manager Configuration
After the software has been loaded to the disk, the system will attempt to reboot. Before it begins the bootup process, press the front panel reset button. This will stop the bootup process, and allow you to make the final configuration changes to be able to boot directly from the disk, instead of the floppy or CD-ROM. You should now be at the SRM prompt, ">>>". Enter the following commands to finalize the configuration.
You need to enter these commands, such that the drive reference on the second line needs to refer to the drive which you installed to:
>>>set boot_file 2/boot/vmlinux.gz >>>set bootdef_dev dka0 >>>set boot_osflags "root=/dev/sda2" >>>boot dva0 -fi vmlinux.gz
Note - When the system boots, you may see a series of warnings similar to the following: system.map - incorrect version This warning indicates that the kernel version that you installed (i.e. the latest version that you

The system may or may not hang here. This is a known issue and is being worked on. Please reset or power cycled the system to continue with installation.
At the SRM prompt, you can now boot directly from the hard drive:
>>>boot
The system should now boot and prompt you to login. Upon logging in, you will probably want to configure the X Window System. To do so, login as the user "root", and then run the command "xf86config". Following the prompts answering the questions appropriately for your system. In most cases, you will need to select "3Dlabs Oxygen GMX" as the graphics adapter, which is usually configured with 8192K bytes of memory. Once this process is completed, you should be able to run the command "startx" to make use of the graphical interface.

Red Hat Version 6.0 Distribution
Pre-Installation
Creating The BOOT Floppy
Before you can begin to install the Linux software on your AlphaServer or AlphaStation, you will need to create a BOOT floppy. This floppy contains the information required to initiate the installation of Linux. The process varies depending upon what software distribution you are using.
An important note: Our experience has shown that the vendor supplied floppy images sometimes do not work properly. You are therefore encouraged to create your own BOOT floppy using the images available over the Internet, as described in the sections that follow.
Creating floppies using a MS/Windows system
To create the BOOT floppy, you will need to make use of a PC, which has Internet access. The instructions below detail the process:
1. Create a directory on the PC into which you will copy files for Linux, for example \Linux.
2. Connect to the URL ftp://ftp.digital.com/pub/DEC/Linux-Alpha/Images/ which is a directory containing the boot floppy image files.
3. Copy the generic-smp-2.2.12.img file to your PC.
4. Rename the file to generic.img (DOS has an 8.3 file name limitation)
5. Insert the Linux CD-ROM into the PC.
6. Copy the file "\dosutils\rawrite.exe" from the CD-ROM to the \Linux directory on the PC.
7. Insert a blank, formatted floppy into the PC.
8. Run the following command from the DOS command shell:
C:\Linux> rawrite Enter source file name: generic.img Enter destination drive: a
Label this floppy "AlphaServer Linux BOOT Floppy".
With this floppy in hand, you are now prepared to begin the installation process on your AlphaServer or AlphaStation.
Creating floppies using an Unix system
To create the BOOT floppy, you will need to make use of a computer, which has Internet access. The instructions below detail the process. Note that depending upon what version of unix and vendor computer you are using to perform this process, some minor variations in the process may be required. The exact commands shown here are for Digital Unix, and should be similar to most other popular unix systems.
1. Copy the generic kernel images from the Internet to your computer:
ECG513/0100
$ mkdir /var/tmp/Linux $ cd /var/tmp/Linux $ ftp ftp.digital.com login: ftp
Linux Installation and Configuration Guide for AlphaServer 25
Password: user@ ftp> bin ftp> cd /pub/DEC/Linux-Alpha/Images/ ftp> get generic-smp-2.2.12.img ftp> quit
2. Insert a blank, formatted floppy into the computer, and copy the BOOT kernel to it:
$ dd if=generic-smp-2.2.12.img of=/dev/fd0
With this floppy in hand, you are now prepared to begin the installation process on your AlphaServer or AlphaStation.
Firmware Inspection and Upgrade
After powering up your AlphaServer or AlphaStation computer, type the command "show version". Check that the version string printed is "V5.4-2 May 19 1999 14:25:16" or newer, and that the first letter of the version string is a "V". If this is not the case, you should upgrade your firmware. Instructions on how to do this can be found at
http://ftp.digital.com/pub/Digital/Alpha/firmware/ along with the latest firmware images.
System Resource Manager Configuration
There are several pieces of information that you need to configure in the SRM subsystem, as well as device identifiers that you should make note of, prior to beginning the installation process. The steps that follow take you through that process.
1. Power up your system. After several diagnostics are completed, you will be presented an SRM prompt "P00>>>", as shown here:
1024 Meg of system memory probing hose 1, PCI bus 0, slot 7 -- ewa -- DE500-AA Network Controller bus 0, slot 8 -- pka -- QLogic ISP1020 probing hose 0, PCI probing PCI-to-ISA bridge, bus 1 bus 0, slot 5, function 1 -- dqa -- Cypress 82C693 IDE bus 0, slot 5, function 2 -- dqb -- Cypress 82C693 IDE bus 0, slot 8 -- pkb -- QLogic ISP1020 bus 0, slot 9 -- vga -- ELSA GLoria Synergy System Temperature is 24 degrees C initializing GCT/FRU at offset 1d0000
AlphaServer DS 20 Console V5.4-2, May 19 1999 14:25:16 P00>>>
2. Determine what devices your system has installed. In particular you will need to note your installation device (a floppy and/or CD-ROM), and your target disk drive. Entering the command "show devices" as shown below will print out the information about your system:
P00>>>show device dka0.0.0.8.1 DKA0 RZ1DF-CB 0371 dkb500.5.0.8.0 DKB500 RRD46 1337 dva0.0.0.0.0 DVA0 ewa0.0.0.7.1 EWA0 00-00-F8-10-AE-C5 pka0.7.0.8.1 PKA0 SCSI Bus ID 7 5.57 pkb0.7.0.8.0 PKB0 SCSI Bus ID 7 5.57
ECG513/0100
In the output above, the first line shows that DKA0 is a hard disk, DKB500 is a CD-ROM, and DVA0 is a floppy drive.
