Introduction:
=============
PXE is short for the Preboot Execution Environment. This PXE bootrom is built by
PXE SDK 2.0 build 082, so it full supports PXE Specification 2.1.
Contents of the Subdirectory:
=============================
PXE.TXT This file.
PXEM.LOM The bootrom binary file with bootstrap menu for Lan On
Motherboard.
PXEM.NIC The bootrom binary file with bootstrap menu for Network Interface
Card.
PXEB.LOM The bootrom binary file without bootstrap menu and supporting BEV/
PNP
only for Lan On Motherboard.
PXEB.NIC The bootrom binary file without bootstrap menu and supporting BEV/
PNP
only for Network Interface Card.
Installation:
=============
Before starting the installation process, make sure that the adapter
is properly installed and configured. You can use the diagnostic program
(A:\DIAG.EXE) to make sure your connection with the network is correct.
PXE EEPROM Options
-------------------
After POST of BIOS, BootROM will waiting a short time to change boot method.
If user strike <Shift-Tab> key, PXE will show some advenced menu and you
have 2 options in it:
Boot Protocol
Boot Option
And if no <Shift-Tab> key, PXE will boot according EERPOM value. please
refer EEPROM.doc to get more informatin about their configuration.

Introduction:

PXE is short for the Preboot Execution Environment. This PXE bootrom is built by PXE SDK 2.0 build 082, so it full supports PXE Specification 2.1.

Contents of the Subdirectory:

PXE.TXT This file. PXEM.LOM The bootrom binary file with bootstrap menu for Lan On Motherboard. PXEM.NIC The bootrom binary file with bootstrap menu for Network Interface Card. PXEB.LOM The bootrom binary file without bootstrap menu and supporting BEV/ PNP only for Lan On Motherboard. PXEB.NIC The bootrom binary file without bootstrap menu and supporting BEV/ PNP only for Network Interface Card.

Installation:

Before starting the installation process, make sure that the adapter is properly installed and configured. You can use the diagnostic program (A:\DIAG.EXE) to make sure your connection with the network is correct.

PXE EEPROM Options

After POST of BIOS, BootROM will waiting a short time to change boot method. If user strike key, PXE will show some advenced menu and you have 2 options in it:

Boot Protocol Boot Option

And if no key, PXE will boot according EERPOM value. please refer EEPROM.doc to get more informatin about their configuration.

  1. Boot Protocol

You cannot change boot protocol.

  1. Boot Option There are 4 options: Network First, Then Local Local First, Then Network Local Only According BIOS

A. Network First, Then Local

This option is chosen to boot network by hooking INT 19. Since INT 19 is booting vector, our device is always chosen to boot regardless of IPL priority.

B. Local First, Then Network

This option is chosen to boot from network by hooking INT 18h. Since INT 18h is boot recovery vector, so only after other local devices with higher IPL prioirty failed to boot successfully then we may boot.

C. Local Only

This option is chosen to boot from local devices, not to boot from network.

D. According BIOS

This option is chosen to boot network by PnP/BEV. Whether to boot or not according IPL priority. The proiority for IPL devices is configurable by the user by editing the IPL Priority in BIOS Setup.

If user enter any option and press to save, PXE will write back into EEPROM. Pressing will ignore any modification and booting according EEPROM setting.

When you use PXEB.LOM and PXEB.NIC:

This is for network boot by using PnP/BEV (BBS). Whether to boot or not according IPL priority. The proiority for IPL devices is configurable by the user by editing the IPL Priority in BIOS setup.
