To boot over the network by using PXE, you need the following systems.
An install server
A DHCP server
An x86 client that supports PXE
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.
