Alternative Method for Initialization
of Ethernet Controller
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
Note:
The INIT bit must not be set or the initialization block will be accessed instead.
