I/O MINI II                                         AST Part Number 202123-001

The I/O Mini II is a multifunction board for the IBM PC, PC/XT, and 100%
compatibles running at 4.77MHz.  This board comes standard with a real-time
clock/calander, a serial port configurable as COM1: or COM2:, and a parallel
port configurable as LPT1: or LPT2:.  Optional upgrades include a second
serial port and a game port.


JUMPER SETTINGS

    Jumper positions E1 through E7 are three pin jumpers.  E1-E6 control the
    signals sent to the serial ports, and for the most part should remain in
    the default position (on pins 1 & 2 to the left).  In rare cases, you may
    want to force certain signals true, in which case the appropriate jumper
    would move to the right pair of pins (2 & 3).

        E1 - Move to 2 & 3 to force CTS true (Port One)
        E2 - Move to 2 & 3 to force DSR true (Port One)
        E3 - Move to 2 & 3 to force DCD true (Port One)

        E4 - Move to 2 & 3 to force CTS true (Second Port Option)
        E5 - Move to 2 & 3 to force DSR true (Second Port Option)
        E6 - Move to 2 & 3 to force DCD true (Second Port Option)

    Slot eight (closest to the power supply) in the IBM PC/XT is a
    non-standard slot.  If the I/O Mini II is installed in this slot, you must
    move the jumper at E7 to right pair of pins (2 & 3).

        E7 - Move to 2 & 3 if installed in PC/XT slot 8
