• Manufacturer Part Number: am79c970
• Description: Pcnettm-pci Single-chip Ethernet Controller For Pci Local Bus
• Manufacturer: Advanced Micro Devices

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