Ethernet LED Status
ACT (green): This LED monitors network connection and activity. The LED lights up when net-
work packets are sent or received through the RJ45 port. When this LED is not lit it means that
either the computer is not sending or receiving network data or that the cable connection is
faulty.
SPEED (green/orange): This LED lights up to indicate a successful 10Base-T or 100BASE-
TX connection. When green it indicates a 10Base-T connection and when orange it indicates
a 100Base-TX connection.

EIDE Interfaces
The EIDE interfaces support the following modes:
• Programmed I/O (PIO): CPU controls data transfer.
• 8237-style DMA: DMA offloads the CPU, supporting transfer rates of up to 16 MB/sec.
• Ultra DMA: DMA protocol on IDE bus supporting host and target throttling and transfer
rates of up to 33 MB/sec.
• ATA-100: DMA protocol on IDE bus allows host and target throttling. The ICH4 ATA-100
logic can achieve read transfer rates of up to 100 MB/sec and write transfer rates up to
88 MB/sec.
Note ...
Due to the high transfer rate of ATA-100, a specialized cable which has
additional grounding wires to reduce reflections, noise, and inductive coupling
is required. This cable will also support all legacy IDE drives.
