HP Ethernet 10/100 BaseT Network Board

Remote Power-On (RPO)

There is a cable from the Remote Start connector, on the network board, to

 

the External Start connector, on the system board. This is used by the

 

Remote Power-On feature (RPO) that is described on page 71. This cable

 

must be routed through the hole in the chassis. Not doing so, and allowing

 

the cable to be routed with the flexible disk drive and IDE cables, will raise

 

the risk of radio frequency interference (RFI) cross-talk.

 

The board is supplied with power, even whilst the rest of the computer is

 

turned off, via a line called VStandby on the External Start Connector. This

 

connector also carries the control lines which the network board uses to

 

turn on the main power supply, and to send or receive other control and

 

status information.

 

When shutdown into its RPO state, the 10 BaseT side of the board draws 30

 

mA, well within the 50 mA capability of the special RPO power supply. (The

 

100 BaseT side of the board would draw more than 50 mA if connected, and

 

hence does not support RPO).

Look-Ahead Packet

Standard drivers wait until a complete frame has been received before

Processing (LAPP)

processing it, and passing it to the application buffer. They then wait for the

 

controller buffer to be empty before starting to receive the next frame.

 

If there are many small frames, and a large amount of Windows application

 

switching, the network utilization rate can fall below 50%. The PC-Net

 

controller utilization of the system bus is about 4%. The remaining 96% can

 

be used by suitable LAPP drivers to start inter-frame data transfers to the

 

application stack buffer. By reducing the latency between frame reception,

 

the network utilization and throughput is increased.

Drivers

The board can be configured completely by software (no switches or

 

jumpers need changing). Drivers for the network board are supplied with

 

the computer. At the time of release, these bear the version number P.01.05.
