MKIMAGE Boot Image Utility for LANtastic
========================================

Features of MKIMAGE
===================

The MKIMAGE utility creates boot images for use with the
Remote Boot feature of LANtastic for DOS and Windows.  Boot
images are normally created from within the Remote Boot
Maintenance menus in the NET_MGR program.  MKIMAGE offers
the following advantages over NET_MGR:

1.  MKIMAGE will create boot images from any of the following
diskette formats:  360K 5.25 inch, 1.2M 5.25 inch, 720K 3.5
inch, and 1.44M 3.5 inch.  NET_MGR requires a 360K diskette
to create a Find/Found image.

2.  MKIMAGE will automatically "defragment" the disk image
while it copies it to the hard drive.  NET_MGR always creates
an image file matching the size of the diskette, including
gaps for deleted files.

3.  MKIMAGE will create a disk image which is the exact size
required to hold the files copied from the diskette.  A 
Find/Found image can exceed 360 KBytes.  The image is copied
into a RAMDisk area on the workstation during the boot
process and it may or may not fit into available memory.  
Images up to 420 KBytes will usually fit, depending on the
use of upper memory blocks and TSR memory requirements.


Usage
=====

MKIMAGE requires two parameters, a drive letter and an image
file name.  The drive letter must be either A: or B:.  The
image file name is entered without a path or an extension.
MKIMAGE will use the LAN_DIR environment variable to
determine the control directory path and will place the image
in the proper sub-directory (usually C:\LANTASTI.NET\SYSTEM.NET).
If LAN_DIR is not defined, MKIMAGE will place the image file
in the current directory and the user will need to copy it to
the control directory.

Sample command line:

mkimage a: myimage

Creates a defragmented and sized boot image file "MYIMAGE.IMG"
from the files and directories found on the diskette in the A:
drive.  The image will be placed in the SYSTEM.NET hidden sub-
directory of the control directory specified by the SET LAN_DIR
line of the STARTNET.BAT file or in the current directory if
LAN_DIR is undefined.


After MKIMAGE
=============

After you create an image file with MKIMAGE, you will still
need to add the image to the image database.  The instructions
below include steps for using LANtastic Power Suite to support
3rd party adapters and boot ROMs via IBM Standard RPL.

If the image is a Find/Found type used by 3rd party adapters
and Boot ROMs or Artisoft Noderunner adapters, and the image
size exceeds 360 KBytes, you will first need to follow these
steps:

1.  Edit the FFRPL.TYP file in the SYSTEM.NET hidden
    sub-directory of the control directory
    (usually C:\LANTASTI.NET\SYSTEM.NET\FFRPL.TYP).

2.  Modify the line:
        maximagesize=1
    to:
        maximagesize=0

    This disables the 360 KByte maximum image size checking
    done by NET_MGR and SERVER.

3.  Save and Exit editing of FFRPL.TYP.

-----
To add the image to the image database, follow these steps:

1.  Run NET_MGR, highlight the Remote Boot Maintenance option
    and press <Enter> to display the image database.

2.  Press <Insert> to add a new image.

3.  Highlight the boot type.  If you are using 3rd party
    adapters and Boot ROMs or Artisoft Noderunner adapters and
    Boot ROMs, select Find/Found and press <Enter>.

4.  Highlight the boot strap loader.  For 3rd party adapters,
    select "FFIBMRPL - F/F RamDisk, IBM Standard RPL" (only
    available in Power Suite) and press <Enter>.  For Artisoft
    Noderunner adapters, select "FFRAMRPL - F/F RamDisk, Novell
    Enhanced RPL" and press <Enter>.

5.  Select the image you created with MKIMAGE and press <Enter>.
    If your image does not appear in the list of available
    images, check that the file exists in the correct location
    in the control directory with an "IMG" extension and that
    FFRPL.TYP has maximagesize=0 if your Find/Found image is
    larger than 360 KBytes.

6.  If you wish to restrict your image to a specific workstation
    node address, highlight the image and press <Enter> to modify
    settings.

7.  Press <ESC> until you exit NET_MGR.

-----
To enable Remote Boot Support on the server, follow these steps:

1.  Run NET_MGR and select the Server Startup Parameters option.

2.  Type <Enter> to confirm the location of SERVER.EXE.

3.  Highlight Remote Booting and press <Enter> until it displays
    ENABLED.

4.  Press <ESC> until you exit NET_MGR.

-----
After the image is in the database and server has Remote Boot
support enabled, you must shut down and restart the server:

1.  Make certain that no users are currently logged into the
    server.  Shut down server by pressing <CTRL+ALT+DEL> and then
    typing 'S'.

2.  Restart the server by typing SERVER at the command prompt.


-----
You may now remotely boot workstations from your image.
