Setting up the Client
1. Select and program the proper PXE image.
2. Enable/disable the PXE driver with the Broadcom DOS utility that is provided.
3. Set up the BIOS for the boot order.
Selecting/Programming the Proper PXE Image
PXE is released with three different images:
b44pxe.lom. This is a monolithic image that consists of both PXE base-code (BC) and UNDI code. This
image should be used on the adapter where the motherboard does not have a built-in BC. However, an
adapter programmed with this image is still operational in the motherboard's BIOS with built-in BC.
The BC on the adapter is not used.
b44undi.lom. This is an UNDI image that consists of UNDI code only (split implementation). This
module should be programmed on the adapter where the motherboard's BIOS has built-in BC.
basecode.lom. This is a BC image that consists of BC code only (split implementation). This module
should be programmed on the motherboard's BIOS.
The PXE image can be programmed to the adapter serial EEPROM or the motherboard BIOS LAN on
Motherboard (LOM). For LOM, the PXE image has to be integrated into the OEM BIOS. For the adapter,
the PXE image is programmed into the EEPROM during the manufacturing process.
Boot Method
By default, PXE detects if the BIOS supports BBS (BIOS Boot Specification). If the BIOS supports BBS,
then PXE uses BBS as the boot method.
PXE Speed
By default, PXE is set to auto-negotiate.
Setup BIOS
To boot from the network with PXE, make PXE the first bootable device under BIOS. This procedure
depends on server BIOS implementation. Refer to the server user manual for information.
