	DAVICOM DM9PCI Seriese Fast Ethernet Adapter PXE Boot ROM
			Installation Guide

1. Who am I?
   ---------

PXE-RPL.ROM : Monolithic PXE Boot ROM + RPL(use INT 19h) Boot ROM for EPROM/flash

PXE-DM9.ROM : PXE Boot ROM code only, you can combine it with RPL Boot ROM using
	      DOS COPY command to make a monolithic PXE+RPL Boot ROM by yourself


2. Which Bootstrap Selection Should I use?
   ---------------------------------------

While system booting up, DM9PCI PXE Boot ROM will display a greeting message,
current boostrap selection and promt you to hold down both (left and right)
sfit keys to pop up the bootstrap selection menu, where you can change the
bootstrap selction.

If you ignore the message for about 5 seconds, it will use the current
bootstrap setting. And if your hold down both the sift key, a bootstrap
selection menu will pop up like this:

	  Bootstrap Selection Menu
	  ------------------------
	1 - Disable network boot
	2 - Network boot using interrupt 18h
	3 - Network boot using interrupt 19h
	4 - Network boot using PnP/BEV (BBS)
	5 - Network boot using RPL

	Press 1, 2, 3, 4, 5:

The options are described as the following:

    (1). Disable network boot

	 Disable the Boot ROM and will not try to remote boot through NIC

    (2). Network boot using interrupt 18h

	 if "Network boot" is supported in your BIOS's boot device order list

    (3). Network boot using interrupt 19h

	 In the old platform where BIOS did not support BBS
	 (Bios Boot Specification), nor network boot in its boot device list

    (4). Network boot using PnP/BEV (BBS)

	 If your BIOS support BBS (BIOS Boot Specification)

    (5). Network boot using RPL

	 Remote network boot using RPL rather than PXE, the RPL BOOT ROM
	 may use INT 18h or INT 19h depends on which RPL code is combined
	 into the monolithic PXE+RPL Boot ROM.

3. How to make a monolithic PXE+RPL Boot ROM by Yourself
   -----------------------------------------------------

PXE Boot ROM has the bootstrap selection menu to choose which bootstrap
approach is used in diffrent platform. However, the boostrap approach
used by the RPL Boot ROM is hardcode in the RPL code. So whether RPL
use INT 18h ,INT 19 or some other thing depends on which RPL code
is combined into the PXE+RPL monolithic Boot ROM.

You can make a monolithic PXE+RPL Boot ROM by yourself.

1. Get the RPL Boot ROM code which meets your system requirement.

   That is, if your system can only remote boot using INT 19h, get the
   RPL code which uses INT 19h as its bootstrap approach.
   if your system can only remote boot using INT 18h, get that code image.
   They may be named like this:

   RBOOT19.ROM - RPL remote boot using INT 19h
   RBOOT18.ROM - RPL remote boot using INT 18h

2. using COPY command to combine the PXE Boot ROM with RPL Boot ROM

   Under DOS command prompt:

   >COPY /B PXE-DM9.ROM+RBOOT19.ROM PXE-RPL19.ROM

   or

   >COPY /B PXE-DM9.ROM+RBOOT18.ROM PXE-RPL18.ROM
