Appeal No. 1997-3821
Application No. 08/570,256
controller chip connected to the connector, an internal
parallel data bus connected to said controller chip,
transceiver means for controlling the transfer of
configuration data bits from said expansion circuit
board to a second parallel bus extending from a
connector to a host computer and a memory connected to
said internal parallel bus, comprising the steps of:
programming configuration data bits which define
the address space occupied by said expansion circuit
board
with respect to a host computer into said memory, said
configuration data bits enabling said host computer
to communicate commands to and receive input from said
expansion circuit board;
connecting said connector to said host computer,
said controller chip being electrically coupled to said
host computer when said connector is connected to the
host computer, and said controller chip being
electrically decoupled from the host computer when said
connector
is disconnected from the host computer;
determining when power is supplied to said
controller chip and said other components of the expansion
circuit board;
generating a control signal in response to said
determining step;
providing said control signal to said memory; and
transferring said configuration data bits to said
controller chip over said internal parallel bus
independently of a command from said host computer,
wherein, when said configuration data bits are
transferred from said memory to said controller chip
[sic].
