Ethernet
Refer to Figure 2–1 for the location of various connectors.
The 5445E Video / Ethernet card provides a 10Base–T Ethernet port
and supports the IEEE 802.3 Ethernet standard. The Ethernet
controller IC chip provides the following:
8K x 16 SRAM buffer
Integrated 10 Base–T transceiver interface
The 5445E card uses twisted–pair wiring cable, which is built in a star
configuration. The interface terminates at the standard, 8–position,
RJ–45 latching phone jack.
Note
There cannot be more than one Ethernet port in the Micro PC system.
IRQs
IRQ3, IRQ4, and IRQ5 connect directly to the bus. IRQ10 and IRQ11
can be routed to bus IRQ3 through jumper W8.
Table 2–3 W8 – Ethernet IRQ select jumper

Description
[1-2]
IRQ11 to bus IRQ3
[2-3] *
IRQ10 to bus IRQ3
* default
Note
The IRQ selected for the 5445E card must have a matching IRQ on the
Octagon CPU card. Different Octagon CPU cards route internal and
external IRQs differently. Refer to your CPU manual to determine
which IRQ to use.
