x86: Overview of Booting and Installing Over the Network With PXE
This section provides an overview of the Preboot Execution Environment (PXE).
x86: What is PXE?
PXE network boot is a “direct” network boot. No boot media is required on
the client system. With PXE, you can install an x86 based client
over the network by using DHCP.
PXE network boot is available only for devices that implement the Intel Preboot
Execution Environment specification. To determine if your system supports PXE network boot, see
your hardware manufacturer's documentation.
x86: Guidelines for Booting With PXE
To boot over the network by using PXE, you need the following
When you are preparing to use PXE to install a client over
the network, consider the following issues.
Set up only one DHCP server on the subnet that includes the client system that you want to install. The PXE network boot does not work properly over subnets that include multiple DHCP servers.
Some early versions of PXE firmware have a variety of shortcomings. If you experience difficulty with a particular PXE adapter, obtain firmware upgrade information from the adapter manufacturer's web site. Refer to the elxl(7D) and iprb(7D) man pages for more information.
