Wake on LAN PXE question

[Bodezafa]

Hello all, I'm a new member :thumbup
Wondering if you could answer a question for me?
What is the difference between Wake On LAN and PXE?
Can you use PXE if wake on LAN is not enabled in BIOS?
TIA
Derek.

Welcome to short-media. It's good to see another local (there are a lot of Michiganders on this site)

WoL and PXE are entirely different things - WoL is simply a mechanism to power on the computer when the network card receives a specific "wake up" packet.

PXE is Preboot Execution Environment - it's sort of a mini-OS for headless workstations. The PXE does not require WoL, it requires a managed network card that has a BIOS chip on the card itself.

PXE is used to boot the computer from the network - there doesn't need to be a disk present. If you want to wake the computer over the network from a shutdown state, you need WoL.

So if you want to boot from the network, but the PC is powered off, you need to wake it with WOL and then boot from the network with PXE :confused:
Sorry but I have never had a use for this and noe I'm trying to learn it.

WOL: Means you can turn the computer on at another location. It can have its own HDD on the computer with the WOL.

PXE: You can phyically touch the power button and the computer will boot files across the network. The files are stored on another computer so a network boot.
