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 100Base-TX or
1000BASE-T connection. When green it indicates a 100Base-TX connection and when orange
it indicates a 1000Base-TX connection. When not lit and the ACT-LED is active, the connection
is operating at 10Base-T.

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-66: DMA protocol on IDE bus supporting host and target throttling and transfer rates
of up to 66 MB/sec. ATA-66 protocol is similar to Ultra DMA and is device driver compat-
ible.
• ATA-100: DMA protocol on IDE bus allows host and target throttling. The 6300ESB ATA-
100 logic can achieve read transfer rates of up to 100 MB/sec and write transfer rates up
to 88 MB/sec.
Figure 2-7: EIDE Interface Connectors J19 and J20
There are two independent EIDE ports available. The primary port is connected to the 44-pin,
2-row male connector, J19, and to the onboard CompactFlash socket, J17. The secondary
EIDE interface is a 40-pin, 2-row male connector, J20, AT standard interface for an EIDE hard
disk. This interface is also available at rear I/O.
The onboard 2.5" HDD can be installed on the 44-pin connector.
Note ...
ATA-66 and ATA-100 are faster timings and require a specialized cable which
has additional grounding wires to reduce reflections, noise, and inductive
coupling. This cable will also support all legacy IDE drives.
