ADAPTER PROGRAMMING

Programming the adapter consists of configuration, which occurs during POST, and control,
which occurs at runtime.

D.4.1 CONFIGURATION

The adapter's 82559 or 82550 NIC controller is a PCI device and configured though PCI
configuration space registers using PCI protocol described in chapter 4 of this guide. The PCI
configuration registers are listed in the following table:

00-01h Vender ID
02-03h Device ID
04-05h PCI Command
06-07h PCI Status
08h Revision ID
09-0Bh Class Code
0Ch Cache Line Size
0Dh Latency Timer
0Eh Header Type
0Fh BIST
NOTE:
Assume unmarked gaps are reserved and/or not used.

D.4.2 CONTROL

The adapter's 82559 or 82550 controller is controlled though registers that may be mapped in
system memory space or variable I/O space. The registers are listed in the following table:
