PREFACE
This document is an update to published specifications. There are two current specification documents:
•
82543GC Gigabit Ethernet Controller Datasheet, Intel Corporation.
•
OR-2710 82543GC Gigabit Ethernet Controller Developer's Manual, Intel Corporation.
This document is intended for hardware system manufactures and software developers of applications, operating systems or tools.
It contains Specification Changes, Errata, Specification Clarifications, and Documentation Changes.
The changes/errata/clarifications described in this document will be incorporated into the next release of 82543GC Gigabit Ethernet
Controller Data Sheet, the 82543GC Gigabit Ethernet Controller Developer's Manual.
NOMENCLATURE
Specification Changes are modifications to the current published specifications. These changes will be incorporated in the next
release of the specifications.
Errata are design defects or errors. Errata may cause 82543GC device behavior to deviate from published specifications. Hardware
and software designed to be used with any given stepping must assume that all errata documented for that stepping are present on
all devices.
Specification Clarifications describe a specification in greater detail or further highlight a specification's impact to a complex
design situation. These clarifications will be incorporated in the next release of the specifications.
Documentation Changes include typos, errors, or omissions from the current published specifications. These changes will be
incorporated in the next release of the specifications.
