Quick Start Instructions

If you are an experienced user, you may follow the quickstart instructions here. If you are unfamiliar with the slave install process, please refer to the detailed instructions below.

  1. Download the files e100_2.2.14-5.0BOOT.o and ks.cfg to an windows (VFAT) floppy.
  2. Plug the machine to be set up into the network and boot the Red Hat 6.2 install CD.
  3. Insert the floppy when the installer boot prompt appears. Type linux ks=floppy
  4. When the installer restarts the machine, remove the floppy and the CD. Wait for the machine to boot up and reboot once more.
  5. The install is complete.

Pre-Install Instructions

Note: Words in monotype are either filenames or actual commands to be entered.

The pre-install should be performed on a machine with windows or linux installed and configured so that it can read and write windows (VFAT) floppies and access the network. This need not be the machine that you are going to install on.

  1. Obtain a Redhat 6.2 CD.
  2. Make an windows floppy for storing the configuration files:
    1. Make sure you are using a high density, 1.44 Mb floppy. Format the floppy to using an windows file system.
      • If you are using a linux box use the commands:
          fdformat /dev/fd0H1440
          mkdosfs /dev/fd0
      • If you are using a Windows machine, right click on the floppy and choose "format: full" Kevin: check this
    2. Download the ethernet driver and configuration file to the floppy. Do this by saving the two links below to floppy. If you are using netscape for linux, right click on each link, choose "Save as..." and save the link as source to your local disk. Then copy the files to the floppy disk. If you have problems copying these files to the floppy, see the instructions below.

Installation Instructions

The install should be performed on the machine that you wish to turn into a bewoulf slave node. It should be connected to the internet so that it can access the machine via http during the install process. You need the Red Hat 6.2 CD and the floppy created according to the instructions above. The install should performed with a monitor, keyboard and mouse connected to the node. These can be disconnected after the install has completed and you have powered down the machine.

  1. It is assumed that the BIOS has already been configured correctly according th the instructions elsewhere, but to avoid clock conflicts, set the hardware clock's time correctly:
    1. Power up the machine and hold F2 or DEL to enter the BIOS.
    2. Go to the Main section of the BIOS. Move down to the System Date.
    3. Following the instructions on the bottom left of the screen, set the date to the current time in UTC (GMT). This is CST + 6 hours (CDT + 5 hours).
    4. Exit the BIOS, saving these changes.
  2. Boot the machine with the Redhat 6.2 installation CD in the drive.
  3. When the Red Hat boot menu appears insert the floppy into the drive.
  4. Type linux ks=floppy at the boot prompt and hit enter.
  5. When the Red Hat 6.2 installation is done the machine will eject the CD and reboot. Removed the CD from the tray before it closes. You have about ten seconds or so to do this. But don't panic if you don't get it in time.
  6. Once the machine has restarted, remove floppy from the drive to prevent the machine attempting to boot again from the floppy. Make sure that you do not remove the floppy while the drive light is on. If the machine tries to boot from the floppy, it will fail to boot with the message "This is not a bootable floppy." Simply remove the floppy and press any key. The install will continue unperturbed.
  7. The machine will now load the freshly install distribution. When it boots, you will see an error message from depmod. This only occors once here and can be ignored.
  8. If the install has been sucessful, a message will be displayed on the screen and machine will then reboot once to ensure that all configuration files have been updated.
  9. As the machine reboots, shutting down atd will give a "failed" message. This only occours once here and can be ignored.
  10. If the install fails for any reason, a message will be display on the screen. You may then log in and invesitgate the log files in /tmp

This completes the install


Copying Files to the Floppy

Non-standard X Configuration

Three X configuration files are available for monitors. These are:
  XF86ConfigVX1120 for use with the Gateway 21" monitors.
  XF86ConfigE771 for use with the old Viewsonic 17" monitors.
  XF86Config770TFT for use with the SyncMaster 770 TFT flat screen monitors.

To install these, log in as root to a slave that has been sucesfully set up and run the following command:

cp -f /etc/X11/filename /etc/X11/XF86Config-4

where filename is the name of the appropriate configuration file.

Source RPMS

Source RPMS for the medusa specific packages are available from the medusa cvs archive. These contain source code and a complete description of how the RPMS were built.

More information on RPMS is avaiable from the RPM Home Page. The instructions below are given to get users started, they are not a replacement for the RPM manual.

If you wish to compile an RPM, download the SRPM to the machine that you are working on and install with
  rpm -ivh filename.src.rpm
This installs the RPMS sources to the usual location (/usr/src/redhat). To rebuild the rpm go into the SPECS directory and build with
  rpm -ba filename.spec
