1.1 Introduction and Scope
This document is an update to the Intel® 82580 Quad/Dual Port GbE LAN Controller Datasheet. It is
intended for use by system manufacturers and software developers. All product documents are subject
to frequent revision. Be sure you have the latest information before finalizing your design.
References to PCIe* in this document refer to PCIe v2.0 (5Gbps).

Workaround:
1. SW should not execute bit bang sequences longer than one word at a time.
2. When SW reads the EEC/FLA, it should make sure that it still has the request and
grant; if not it should renew it and re-start the transaction (this does not cover all cases
but reduces the possibility of a problem).
Status:
A1 NoFix
3. Possible System Hang During Enable/Disable When Connecting through nVIdia* IO55 Slot
Problem:
Once the link is up, when the 82580 tries to connect with the nVidia IO55 chipset, the
following may occur:
• The Link layer tries to train but not all lanes work.
• The 82580 tries retraining with fewer lanes; but during retraining may loop.
• The system hangs.
Implication: The 82580 cannot reliably connect using this configuration.
Workaround: Connecting to a different port on the system.
Status:
A1 NoFix
4. SMBus: EEPROM Not Written On ARP If the EEPROM Semaphore Is Taken by SW
Problem:
If an SMBus ARP address is stored at the same time the EEPROM is locked by SW, the
address is not be saved.
Implication : Wrong SMBus address after FW reset.
Workaround: Set the SMBus address in the EEPROM (not through ARP).
Status:
A1 NoFix
5. PCIe Links at x1 Instead of x4 When Attached to Certain Chipset Ports
Problem:
When the device is connected to certain PCIe x4 ports, the PCIe link is x1 instead of x4.
The affected ports on Intel devices have a Device ID of 0x2690. These ports can be found
on:
• 631xESB/632xESB - I/O Controller Hub
• INTEL 3100 SCH Port B
Implications: If the PCIe link is x1, the bandwidth is limited and might not be sufficient for all device
ports, resulting in a performance bottleneck.
Workaround: Do not attach the device to this chipset port. If such a connection cannot be avoided,
please contact your Intel representative for assistance.
