• Description: PCnet-PCI II Single-Chip Full-Duplex Ethernet Controller for PCI Local Bus Product
• Manufacturer: Advanced Micro Devices

Alternative Method for Initialization
The PCnet-PCI II controller may be initialized by per-
forming I/O writes only. That is, data can be written di-
rectly to the appropriate control and status registers
(CSR instead of reading from the initialization Block in
Note:
1. The INIT bit must not be set or the initialization block will be accessed instead.
