What does PXE mean?

Preboot eXecution Environment - In computing, the PXE is a standardized client-server environment that boots a software assembly, retrieved from a network, on PXE-enabled clients.

 

 

PXE Boot Process

  • The device sends out a DHCP broadcast and states that it needs to PXE boot. Performed by hitting F12 on the device as it starts up)

  • The DHCP server picks up this broadcast and replies with a suggested IP address to use

  • The device replies to the server and uses the provided address

  • Then the device contacts the PXE boot server and requests the boot file that it was told to look for from the DHCP server

  • The file is then loaded and launched on the client
