2.11.5 Disabling the Video Controller

The video controller can be disabled by removing the jumper on W1. The default state is enabled, with

the jumper installed.

2.12 ETHERNET NETWORK INTERFACE

This section describes how to configure and connect the Ethernet LAN interface.

There are no jumpers to set on the Ethernet interface, and no hardware configuration, other than

connecting the network cable to an appropriate connector. Software configuration of the Ethernet

interface includes the following steps (mentioned briefly here, and covered in detail in Chapter 3):

 In SETUP, enable the Ethernet interface.

 In SETUP, select the I/O address block. The interface uses a 16-byte block of I/O addresses starting

at 300h, 320h (the default), 360h, or 380h.

 In SETUP, select the Ethernet media you will be using. Select the twisted pair interface if you want

to connect a twisted pair cable to the RJ45 connector. Select the AUI interface if you want to attach

an external transceiver or Media Attachment Unit (MAU) and run on a different medium, such as

thick coax or thin coax.

 In SETUP, select an IRQ. The interface can use either IRQ3, IRQ9 (the default), IRQ10, or IRQ11.

Choose an unused interrupt, as interrupt sharing is not implemented for this interface.

Note

IRQ11 is the default interrupt selection for the SCSI interface.

Only select IRQ11 if you do not have it enabled for the SCSI

interface.

Note

IRQ3 is the default interrupt for serial 2 and an option for serial 4.

Only select IRQ3 if these serial ports are not using it.

 If you plan to boot from the network (that is, if you plan to use the Little Board/P5i as a diskless

peripheral or workstation), set up the boot PROM. See the section, “Setting up a Boot PROM”,

below, for details.

 Install the proper driver for the network operating system you will be running. Normally this is done

by adding a DEVICE= entry in the CONFIG.SYS file. This is covered in detail in Chapter 3.
