## Overview

The Broadcom NetXtreme™ Gigabit Ethernet Adapter has PXE (Preboot Execution Environment) and RPL (Remote Program Load) support. Multi-Boot Agent (MBA) is a software module that allows your networked computer to boot with the images provided by remote servers across the network. The Broadcom MBA driver complies with the PXE-2.1 specification and is released with both monolithic and split binary images. This provides flexibility to users on different environments where the motherboard may or may not have built-in base-code.

MBA operates in a client/server environment. A network consists of one or more boot servers that provide boot images to multiple computers through the network. Broadcom MBA implementation has been tested successfully in the following environments:

- Linux Red Hat PXE server. Broadcom PXE clients are able to remote-boot and utilize network resources (NFS mount, etc…) and to do Linux installation. In the case of a remote boot, the Linux universal driver binds seamlessly with the Broadcom UNDI (Universal Network Driver Interface) and provides a network interface in the Linux remote-booted client environment.

- Microsoft Windows 2000. Remote Installation Services (RIS). Broadcom PXE clients are able to install Windows 2000 Professional from the network.

- Intel APITEST. The Broadcom PXE driver passes all API compliance test suites.

- DOS UNDI. Universal NDIS seamlessly binds with Broadcom UNDI to provide NDIS2 interface to the upper-layer protocol stack. This allows computer s to connect to network resources in a DOS environment.

- 3Com® boot server.

- Microsoft Windows NT 4.0 Remote Boot Sever.

## Client Setup

Setting up MBA client for Broadcom NetXtreme™ Gigabit Ethernet Adapter involves the following steps:

1. Enable/disable the MBA driver with the provided Broadcom DOS utility.

2. Setup the BIOS for the boot order.

### Enable/Disable

To enable MBA, boot up into DOS.

> d:\DOS\utility

> b57udiag -mba [ 0-disable | 1-enable ] -c <devnum>

> where:

> devnum= specific device(s) number (0,1,2,...) to be programmed

###

MBA Protocol

To specify the MBA protocol, boot up into DOS.

> d:\DOS\utility

> b57udiag -mbap [ 0-pxe | 1-rpl | 2-bootp ] -c <devnum>

> where:

> devnum= specific device(s) number (0,1,2,...) to be programmed

### MBA Speed

MBA can be forced to a specific speed. To do this, place the Broadcom software CD in the CD drive (i.e., drive D) and boot up into DOS.

> d:\DOS\utility

> b57udiag -mbas [ 0-Auto | 1-10HD | 2-10FD | 3-100H | 4-100F ]

> where:

> devnum= specific device(s) number (0,1,2,...) to be programmed

### Setup BIOS

To boot from the network with MBA, make MBA the first bootable device under BIOS. This procedure depends on server BIOS implementation. Please refer to the server's user manual.

## Server Setup

### Windows 2000

The current version of Windows 2000 does not include a network driver for the Broadcom NetXtreme™ Gigabit Ethernet Adapter. To do remote installation with PXE, include a network driver for the Broadcom NetXtreme™ Gigabit Ethernet Adapter as a part of the client's installation image on the server. Please refer to Microsoft Article ID Q246184 - "How to Add Third-Party OEM Network Adapters to RIS Installations."

### DOS UNDI/APITEST

To boot in DOS and connect to a network for the DOS environment, download the Intel® PXE PDK from the Intel Web site. This PXE PDK comes with a TFTP/ProxyDHCP/Boot server. The PXE PDK can be downloaded from Intel at http://www.intel.com/support/network/adapter/pro100/bootagent/30619.htm.

### Windows NT 4.0 Remoteboot Server

For instructions on setting up the Windows NT 4.0 Remoteboot Server, refer to Remoteboot (Chapter 15) from the Microsoft TechNet website.
