You will have been supplied with:

Do not remove the interface card from its antistatic bag until you have read through the
Installation Instructions, paying particular attention to the notes on Static Electricity.

This manual.
The CMOS Lock manual.

Installation instructions for your i3 EtherLan card.

support material if you have purchased a card with pre-installed.

General Requirements

For your computer to be used on Ethernet it requires a minimum of 2Mb of RAM. With the
steady increase in the size and power of applications we recommend at least 4Mb memory
(5Mb on a Risc PC) wherever possible. Your computer will also require RISC OS 3,
version 3.10 or later. Older A300 and A400 series computers require the MEMCIa
upgrade; A300 series need a backplane to accommodate the Ethernet card - for reliability, a
four-layer backplane is strongly recommended.

Variations in the

software

There are two variations in the i3 Ethernet drivers which you need to be aware of when
using this manual:

Virtual Ethernet Interface support: The Ethernet drivers for the E500 and E600 series
cards now include support for virtual Ethernet interfaces; i.e. they allow a single network
card to appear to the network as two independent connections. Where a computer is fitted
with a PC card or PC second processor this feature allows the PC and the RISC OS

environments to have full, independent access to the network. This feature is controlled by
anew configuration command,

Configure EHVirtual.

The setting of this

configuration option will affect the output from some commands described in this Guide;

the command descriptions and usage examples given below are for interfaces with the

EHVirtual feature. For more information, please refer to the Application Note: Using A PC

Card with your i3 Ethernet Card (Issue 1.1 or later).

Avignon Bridge software: With the i Avignon bridge software the normal Ethernet driver

module, EtherH, is replaced by a bridge driver module, EtherHB. The co mmands
described in this manual are also provided by the bridge drivers, although in some cases the
output will differ. These differences are described in the Avignon Bridge Software User
Manual 
(Issue 1.1 or later).
