AST Ethernode                                       AST Part Number 202246-001

The AST Ethernode is an 8-bit network adapter for use in the IBM PC/XT/AT and
100% Compatibles.  This board conforms to the IEEE 802.3 standard, and can use
either thin wire coax (50 ohm) or thick wire for increased performance.

Most of the configuration for the AST Ethernode adapter is handled by
software.  The program SSCONFIG sets the IRQ, I/O address, ROM address, etc.
Without the software, configuring this product is not really possible.  The
AST Part Number for the configuration software is 910332-001.


JUMPER SETTINGS

    E1 - Test Point - Leave Jumper Installed

    E2 - "Sleep" Jumper
        When this jumper is removed, it is the same as removing the board from
        the system.  This helps when troubleshooting potential conflicts.

    E3/E4 - Cable Type
        These locations are more terminating resistor than standard jumper.
        Factory default has the resistor pack in the lower position (labeled
        "E4" & "THIN").  This enables the coaxial connection at the rear of
        the board.  If the cable being used has a DB-15 type connector, move
        the resistor pack to E3 (THICK).

    E5 thru E8 - SSCONFIG Board Assignment
        Up to four Ethernode boards can be configured at once by the Smart
        Switch software.  If more than one board is to be configured at the
        same time, each one must have a distinct board assignment, set on this
        block from "A" through "D".
