INSTALLING FOUR 16-PORT DIGIBOARDS
----------------------------------

STEP 1

Make certain that you have already properly installed the first three 
DigiBoards, and verify that they are operating normally before proceeding.  
Refer to the TBBS manual for details. 

STEP 2

Referring to the 16-port DigiBoard illustration in the manual, ensure that the
PAL chips installed on your DigiBoard is numbered as follows:

        PAL Chips               Number Printed on Chip
        PAL Chip 1 (U58)        40000708
        PAL Chip 2 (U46)        40000710

If the PAL chips are not numbered shown above, you cannot continue with the 
installation unless your board is equipped with the proper PAL chips. 

PLEASE NOTE:  YOU MUST PURCHASE YOUR 16-PORT DIGIBOARDS FROM ESOFT IN ORDER TO 
HAVE THE PROPER PAL CHIPS.  DIGIBOARD OR DIGIBOARD RESELLERS OTHER THAN ESOFT 
CANNOT PROVIDE THESE PAL CHIPS TO YOU.

STEP 3

Set your jumpers to match the following:

        J3                      Jumpered
        J1, J2, J4, J5, J6      NOT Jumpered

        J7                      Up (Pins 1 and 2)

        P3                      NOT Jumpered

STEP 4

Carefully install the board in any vacant slot in your machine adjacent to 
the existing third DigiBoard.  The board may be installed in 8-bit, 16-bit or 
EISA 32-bit slots.

STEP 5

Remove the jumper P3 on the existing third DigiBoard.  Connect the daisy chain 
cable between P3 on the third DigiBoard, and P3 on the newly installed fourth 
DigiBoard.  If a daisy chain cable was not requested or supplied when you 
ordered the DigiBoard, you must obtain one from eSoft before you can continue!

STEP 6

Use CEDIT on the MULTI-PORT HARDWARE OPTIONS screen to set the following:

        IRQ     Method          Board Type      Lines   Status Port
        3       Efficient       PC/AT Digi      All     140
        4       Efficient       PC/AT Digi      All     143

STEP 7

Use CEDIT to define one or more ports as follows:

        Line    Base Address    IRQ
        49      270             4
        50      2E8             4
        51      2F8             4
        52      308             4
        53      310             4
        54      318             4
        55      328             4
        56      338             4
        57      340             4
        58      350             4
        59      358             4
        60      370             4
        61      398             4
        62      3A8             4
        63      3E8             4
        64      3F8             4

You do not have to define all of the ports at this time -- define only those 
you need now.
