*******************************************************************************
* Note on compatibility between floppies and installers
* ----------------------------------------------------
*
* NOTE:  Athena 9.1 and later *DO NOT SUPPORT* sun4m based hardware.  There is
*        no longer any supported Sun hardware for which you must use an
*        install floppy.  If you want to install a sparc5, tough.
*
*  Each of the subdirectories 21-28, contain the binaries necessary for
*  creating a Solaris install floppy. The install floppies work in conjunction
*  with the software which runs on the installers (solar, solar2), namely with
*  the "miniroots" on the installers. 
*  In order to be successful in installing a Solaris machine, you have to 
*  use a floppy image that works with what is now deployed on the installers.
*
*  e.g :
*
*  the 28 floppy image will work with a 2.6 (8.3) installer with the 
*  2.8 miniroot.
*  the 26 floppy image will work with a 2.6 (8.3) installer or a 2.5.1 
*  installer which has a 2.6 miniroot.
*  the 25 floppy image will work with a 2.5.1 (8.1) installer 
*
* solar  (18.91.1.251) is an RHEL 5.2 machine, using a Solaris 9 miniroot.
*		solar will install athena 9.3, solaris 9 by default.
* note:
* ====
* 
*
*	sunburn will install athena 9.3 solaris 9

Instructions and files for making a 7.6 install floppy are in:
	/mit/bootkit/solarisinstall/21
Instructions for making 7.7 or 8.0 or ops SunOS install floppy are in:
	/mit/bootkit/solarisinstall/23
Instructions for making an 8.1 install floppy are in:
	/mit/bootkit/solarisinstall/25/README.floppy
	(and below)

  See ./25/cnboot.ps for information from Sun on how cnboot works, and
  in particular how to set cnboot.defaults (you can edit that file before
  creating running fd.install to put specific default values on the
  diskette...as of today, it doesn't know how to construct a default gateway
  from the host's IP address).

NOTE:  Athena 9.1 *DOES NOT SUPPORT* sun4m based hardware.  There is
       no longer any supported Sun hardware for which you must use an
       install floppy.  See section 2a below for the installation
       instructions for installing Ultras and Sun Blades.

1. Make an install floppy (see OPTIONAL note below on customizing):
	- login on an Athena Sun
	- attach bootkit; cd /mit/bootkit/solarisinstall/28
	- look at cnboot.defaults to make sure the defaults look
	  sane; if you want something different, edit the file
	- put a high-density diskette into the floppy dirve
	- fdformat -U
	- volcheck
	- if there are no errors during the format,
		fd.install /vol/dev/aliases/floppy0
	(if vold is not running fd.install /dev/rdiskette)

       
2. How to use the install floppy to install Athena and Sun software:
       1. Halt the machine to be installed.
       2. At the PROM prompt type:
		boot floppy	(for SparcClassics, SparcStation 5)
		boot /fd 	(for ipx machines)
       3. Answer the questions (or take defaults):
             a. The IP address of the machine you install 
                 (if staged, the staging IP address)
             b. The IP address of the gateway (18.subnet.0.1)
             c. The IP address of the server (18.91.1.251)
             d. The netmask (usually 255.255.0.0)


2a. Net install an Ultra or Sun Blade 100: you need to boot off the network:
	boot net:<IP addr of tftp server>,<location of cnboot on the tftp server>,<IP addr of the machine you want to install>
	(currently last-will-and-temperament(18.9.62.62) is our central tftp server)
	e.g to install a machine as stage1.mit.edu:
-->	   boot net:18.9.62.62,cnboot,18.177.1.59
	it is possible that in certain cases you'll need to append the
	router's IP address to the aboveline to get it to work, but
	generally this should not be necessary:
	   boot net:18.9.62.62,cnboot,18.177.1.59,18.177.0.1

3.  After the floppy is ejected, you will see on the screen the question

    Custom installation ? (will default to n in 60 seconds)

    If you do not answer or answer n the current rev will be
    installed.  If you answer y you will be asked :

    Which rev do you want to install ?

	enter 9.1, or 9.0 (or some other appropriate number)

    You will also be asked if you want to partition the disk yourself.

4.  Once the machine has installed, please visit:

	http://web.mit.edu/acs/athena-pws-reg.html

    to register the machine.

OPTIONAL Note:
	  [OPTIONAL] if you want to make special default values for the
	  boot floppy prompts (say, if you have to install lots of
	  workstations on the same subnet), save the file
	  /mit/bootkit/solarisinstall/25/cnboot.defaults then edit a new
	  one. MAKE SURE YOU GET IT RIGHT, BECAUSE YOU WON'T KNOW IT'S WRONG
	  UNTIL YOU TRY TO USE THE DISKETTE. Do this step before running
	  	fd.install /dev/rdiskette
