Alternative Method
for Initialization
The PCnet-ISA
ing I/O writes only. That is, data can be written directly to
the appropriate control and status registers (CSR)
instead of reading from the Initialization Block in
memory. The registers that must be written are shown in
the table below. These are followed by writing the
START bit in CSR0.
Note: The INIT bit must not be set or the initialization block will
be accessed instead.
