    PXE Boot

    PXE booting is the most common method used to get machines into a pre-boot environment in order to capture and deploy images, or run provisioning templates. PXE or Preboot Execution Environment has been around for quite a while and allows a machine to boot using a NIC to load a boot image or boot instructions from another computer on the network. For more information about PXE please see:

     

    LANDESK PXE boot

    LANDESK uses a DHCP Proxy, or PXE Representative to implement PXE booting. The PXE software is installed on any machine on a subnet where it listens to DHCP requests. If a request is heard that includes a PXE boot request, the PXE Representative sends the requisite information to allow the client to use the PXE representative as a boot server. An image (WinPE, DosPE or LinuxPE) is then transmitted to the client via TFTP from the PXE representative. That image is loaded into RAM and the machine loads the preboot environment. For more indepth information on the LANDESK PXE process see Understanding the PXE Process.
