Ampro Corporation P5X Setting up a Boot Prom, Ethernet Indicator LEDs, Color Designation Function

Little Board/P5x Technical Manual

!If you plan to boot from the network (that is, if you plan to use the Little Board/P5x as a diskless peripheral or workstation), set up an Ethernet 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. Follow AMD’s instructions for installing your PCnet driver.

Setting up a Boot PROM

Boot PROM code enables the Little Board/P5x system to boot from an Ethernet network server instead of a local hard disk or floppy. Boot PROM code can be installed in the OEM Flash memory on Little Board/P5x, or in an external byte-wide memory socket on a MiniModule or other system board.

If you plan to boot from the network, you must provide a boot PROM program compatible with your network operating system. (You can download AMD PCnet boot PROM code from AMD’s Website.)

You install the boot PROM code in the on-board OEM Flash memory device. Briefly, these are the steps you take:

!Install jumper W11 to write-enable the Flash device.

!Program your boot PROM code into the Flash device using a utility called PGM5X.COM, supplied by Ampro on the utility disk that comes with the Little Board/P5x Development Platform.

!Remove jumper W11 to write-protect the Flash device.

PGM5X is a DOS utility designed to write to the on-board Flash device. (The on-board Flash device contains the system’s BIOS, the video BIOS, the SCSI BIOS.) Instructions for this utility are provided on the utility diskette.

Ethernet Indicator LEDs

Three LED indicator lamps are provided on the board to indicate the status of the Ethernet interface. You can use these LEDs as simple trouble-shooting aids when connecting to an Ethernet segment.

Table 2– 437 shows the meaning of each LED.
