III. DIAG OPTIONS 
=================

The diagnostic program, DIAG.EXE, is provided to you to let you
configure the hardware and test/diagnose the conditions of your
card.  DIAG.EXE can only support one card.  DIAG.EXE will NOT
check whether the user's command conflicts with the system
environment.

1.  Setup Hardware:

    Option allows configuration changes to the IRQ, base I/O,
    media port selection and boot ROM address, if installed.

    Defaults are I/O: 300, IRQ: 15, media port (T model): UTP,
    media port (U model): auto select, boot ROM: disable

2.  Diagnostics:

    Performs simple internal tests to indicate that the card
    should be operating correctly. Do not perform diagnostics
    tests if a driver is loaded.

3.  Network Test

    Allows the PC to behave as either a client or a server
    for testing purposes only.

4.  View Settings

    Displays the card parameters, such as base I/O and IRQ.
    Parameters may not be modified in this option.

--    DOS Command Line Options				  --
------------------------------------------------------------

It is also possible to configure an adapter card with the DIAG
program from the DOS command-line interface.  This method
may be convenient for the network administrator who wish to
prepare and configure many AT-2000 Plus cards for users in an
assembly-line approach.

To run the DIAG program from the DOS command line, the syntax is as
follows:

    DIAG  [parameters]

Parameters may be one or more of the following (in either upper or
lower case):
	/?	 Display help screen
	/D	 Display hardware current status
	/A	 Set hardware automatically
	/Pxxx	 Change the I/O port address
	/Ixx	 Change the interrupt number
	/Mxxxx	 Change the Boot ROM address
	/T	 Change the connector type to UTP
	/B	 Change the connector type to BNC
	/U	 Change the connector type to AUI
	/Cy_n	 Change to compatible or incompatible (CY or CN)

For example:

      1) If you want to display help, type:

		DIAG /? 		[Enter]

      2) To see your current hardware settings, you can type:

		DIAG /D 		[Enter]

      3) If you want to setup your hardware automatically, type:

		DIAG /A 		[Enter]

      Note: The auto configuration function may not work properly
	    under the following circumstance:
		 a) if non-standard peripherals, such as SCSI
		    cards, are in-stalled.
		 b) if some devices (mouse/modem) will be installed
		    in the future.

      4) If you want to change your I/O port address to 280h, IRQ
	 to 5, and Boot ROM address to C400, type:

		DIAG /P280 /I5 /MC400	[Enter]

      Note: 1. You can use /M0 to disable ROM.
	    2. You have to cold start your PC after resetting
	       the Boot ROM address.

      5) You can change the connector type (U model only) setting
	 by typing:

	       DIAG /B		       [Enter]

	  to set your connector type to BNC.

      6) If your PC is fully timing-compatible with the IBM PC/AT
	 bus, type:

		DIAG /CY

	 otherwise, type:

		DIAG /CN
