Appendix D
Alternative Method for Initialization
of Ethernet Controller
APPENDIX D
The Ethernet portion of the PCnet-SCSI controller may
be initialized by performing 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 register
writes are followed by writing the START bit in CSR0.
