2.1: PS/2 Four Diskette Installation Procedure

2.1.1: - Getting Ready
2.1.2: - Memory Expansion Card Exceptions
2.1.3: - Installing on your machine

2.1.1: Getting Ready

  1. To obtain the diskettes needed for the installation, find an existing AIX system (PS/2 or RISC) and do the following:

    Login or "su" to root.

    "format" 4 two-meg diskettes.

    mount -o ro,bg mntsrv0.btv.ibm.com:/afs /mnt

    cd /mnt/btv.ibm.com/ps_aix130/install

    Label the diskettes: Boot1, Boot2, install.net, netmagic.

    Put Boot1 diskette into diskette drive 0

    ./fourdisks xxx

    Where xxx is replaced by the appropriate site prefix. i.e. btv, ccp, end, fsh, owg, or gburg.

  2. The two boot diskettes can be write protected, leave the install.net and netmagic diskettes writable.

  3. cd

  4. umount /mnt and exit

  5. Return to your machine with the diskettes.

    Make sure that you have a token ring network adapter.

    Make sure the token ring adapter cable is plugged into the wall outlet.

    Find out if your ring is a 4 meg or 16 meg ring.

    Note: In Burlington most rings are 16meg.

    Make sure that it is configured for the proper speed (4 or 16 meg).

    Make sure that the port(wall outlet) is active. (DP activates the ports.)

    Make sure your machine is in the nameserver. You should have received notification of your IP address. This means that you are then in the nameserver.

2.1.2: Memory Expansion Card Exceptions

  1. Some PS/2s with the newest memory expansion cards will need to do one extra step for the installation procedure.

  2. If you follow the instructions below and you get the following errors, you have one of the newer cards.

    Only 2 Meg or 128 free pages of memory recognized

    Single user mode entered

    INIT-SU: execle of /etc/su shell failed errno(2)

    INIT-SU: execle of /bin/csh failed errno(2)

  3. The solution is to:

    Boot the system with the memory card option diskette called "Enhanced 80386 Memory Expansion Option".

    Insert the Boot1 diskette when prompted for the boot diskette.

    Follow the rest of the instructions.

2.1.3: Installing on your machine

Note: It is normal during the installation to see messages that look like this: 900-039 - No if_ena adaptors present

  1. Insert Boot1 diskette in diskette drive 0.

  2. Turn on the power switches to the display and other peripherals, then turn on the computer.

  3. If this is the first installation on a machine, you will be asked some questions. Whether this is a new installation or not, be sure the following information has been entered:

    The machine name (not aixps2)

    The display type

    The time zone

    The system language ( U.S. English usually )

    The keyboard language ( U.S. English usually )

  4. Next choose the boot from diskette option and press Enter four times.

  5. Insert Boot2 diskette when prompted.

  6. When the system says to insert either the Installation diskette or the Maintenance diskette, you should insert the install.net diskette.

    If you have two diskette drives in your PS/2, then you may see an error message that says something about "fdopen - no diskette is present in the drive". This is normal and can be ignored.

  7. Select 'Install and customize AIX'

  8. Select 'Install a new AIX System'

  9. Answer (y) to proceed to delete all AIX minidisks.

  10. Select change current choices and install - Toggle (hit space bar) to the various minidisks and change the number of blocks and or files keeping in mind the following:l
    Minidisk70 MB **115 MB> 300 MB
    /u +5000800040000
    / (root)4500086000120000
    page8000 ***8000 ***32000 ***
    undefined *0080000 or more

+ You may choose to set /u to 0 so that you can later modify the size of this filesystem. /u does not have to be installed during the initial install of AIX. Using this procedure, you can set /u to say 10meg later. Then if you find /u getting full, you can make it larger with the minidisks command.

* undefined - You can add other minidisks later with this space.

** A 70 meg harddisk is not recommended but you can install the base operating system, TCP/IP, NFS, and a few other LPP's.

*** Page space should be twice real memory. If you have 16 meg of memory, you need 32,000 blocks of page space. Some of the other numbers may have to change if you need to increase or decrease the page space.

  1. After making all your changes, toggle to "Install the Operating System and Cause the Current Choices to take Effect". Press "Enter" key twice.

    The system will now create the AIX minidisks and install the mini AIX system.

  2. After you receive the 'system halted' message remove the install.net diskette and insert the Boot1 diskette, then press Enter.

  3. Select Boot from diskette

  4. press Enter to accept 'unix.gen' as the module to load

  5. press Enter to accept 'single user' as the mode

  6. Note! Run system from fixed disk must be changed to 'yes'. Press space bar to change the answer to 'yes', then press Enter.

  7. Insert Boot diskette 2 when prompted.

  8. Select Network Install when prompted for method of install and press Enter

  9. The system will ask you to install the Network Installation Option diskette and press Enter, use the diskette labelled netmagic.

    The next set of prompts will have default values that should not need to be changed unless you know for sure that it is wrong. Just press Enter to accept these values and proceed to the next prompt.

  10. The server name should already say ps2server.btv.ibm.com

  11. The server address should be

  12. Enter your machine name when prompted

  13. Enter your TCP/IP address when prompted < example >

  14. The netmask should be

  15. Route thru should be NONE

  16. Routed should be YES

  17. Netdevice should be tk0 (this is the standard token ring)

    For a machine with a busmaster token ring card, such as certain models of the 8595, use bmtk0 instead of tk0

  18. The filesystem name should be /afs

  19. The image path and name should be btv.ibm.com/ps_aix130/images/opsys

  20. Reply y if all the information appears correctly

    The system will now install AIX from the network. This takes quite some time, 20 minutes or longer. When it has finished, there will be a message telling you to press Enter to continue with Post Installation. If there is a message that says that AIX did NOT install successfully, then you will have to start over again.

  21. When prompted, select Normal console login

  22. When prompted, select Continue Installation

  23. When prompted, select End Installation

  24. The system will shutdown and you should then remove the netmagic diskette and press Enter to reboot your system.
