29.6 Enabling PXE on Devices
To image a device using Preboot Services, you need to find out if the device is PXE capable, and
then make sure that PXE is enabled.
PXE code is typically delivered with newer devices (PC 99 compliant or later) on the NIC.
This section includes the following information:
Section 29.6.1, "Enabling PXE on a PXE-Capable Device," on page 401
Section 29.6.2, "Verifying That PXE Is Enabled on a Device," on page 402
29.6.1 Enabling PXE on a PXE-Capable Device
When PXE is enabled, it can lengthen the time of the boot process slightly, so most NICs have PXE
turned off by default. To enable PXE on a PXE-capable device:
1 Access the computer system BIOS and look at the Boot Sequence options.
The PXE activation method for a device varies from one manufacturer to another, but generally
one of the following methods is used:
Some BIOSs have a separate entry in the BIOS configuration to enable or disable the PXE
functionality. In this case, set either the PXE boot setting or the Network boot setting to
Enabled.
Some BIOSs extend the entry that allows you to configure boot order. For example, you
can specify that the system should try to boot from a diskette before trying to boot from
the hard drive. In this case, set the system to try Network boot before trying to boot from a
diskette or from the hard disk.
2 If PXE is not listed in the Boot Sequence options and if the NIC is embedded in the
motherboard, look at the Integrated Devices section of the BIOS, which might have an option
to enable PXE. PXE might be called by another name, such as MBA (Managed Boot Agent) or
Pre-Boot Service.
After enabling PXE in the Integrated Devices section, look at the Boot Sequence options and
move PXE so that it is first in the boot sequence.
3 Save any changes you have made and exit the system BIOS.
4 Reboot the device.
If the device does not have the network adapter and PXE integrated into the motherboard, it uses the
installed NIC management software to prompt you to start PXE configuration during the boot
process.
For example, many network adapters that are PXE-aware prompt you to press Control+S during the
boot process to allow you to configure the PXE functionality. Other network adapters might prompt
you to press Control+Alt+B or another key combination to configure PXE.
