| the risk of radio frequency interference (RFI) |
| 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 board draws 20 mA, well within the |
| 50 mA capability of the special RPO power supply. |
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 T.01.00. |
