Hardware Setup
LAN Jack: 10/100Mbps LAN (for 865PEM2 Series) or Giga-
bit LAN (for 865GM3 Series)
The mainboard provides one standard RJ-45 jack for connection to Lo-
cal Area Network (LAN). Two LAN chipsets are available upon request:
1. 10/100Mbps LAN for 865PEM2-IL mainboard.
2. Gigabit LAN for 865GM3-F mainboard.
Gigabit LAN enables data to be transferred at 1000, 100 or 10Mbps. 10/
100 LAN enables data to be transferred at 100 or 10Mbps. You can connect a
network cable to this LAN jack.
