In this video, we delve into the contemporary applications of Preboot Execution Environment (PXE) in enterprise settings, focusing on its role in bare-metal imaging and rapid re-imaging of virtual machines in data centers. We will explore how some vendors are now offering diskless servers and workstations that rely entirely on PXE for their operation.
We'll cover the essentials needed for setting up a PXE environment, including:
• DHCP Server Configuration: Understanding the importance of DHCP server options 66 and 67 for PXE booting.
• Client NICs with PXE Firmware: Ensuring your network interface cards are PXE-enabled.
• ProxyDHCP Software: When and how to use proxyDHCP to aid in network booting.
A significant part of our discussion will be on the Network Bootstrap Program (NBP) file, its critical role in the PXE environment, and how various vendors implement it.
We'll also review the "boot chain" concepts utilized in PXE and across all operating systems, providing a comprehensive understanding of the boot process.
Additionally, we’ll walk through the steps to configure PXE in your system firmware and demonstrate how to boot into a PXE environment effectively.
This video is designed for both technical professionals and enthusiasts, aiming to present the information in an engaging and insightful manner. Whether you're managing a large data center or setting up a PXE environment for the first time, this guide will provide the knowledge and tools you need.

Dear Mr. Vanderpool, thank you for your videos, everything is explicit and good-structured. Just some question in terms of CPU specification. When looking into any Intel CPU datasheet one can notice lots of applied technologies like Intel Speed Select Technology - Performance Profile, Intel Advanced Matrix Extensions (AMX), Intel Control-Flow Enforcement Technology and so on. Do you happens to have a video with the explanation of all features? Thank you in advance

You can actually do this _without_ support from the DHCP server. That's how the entire Intel PXE system is designed. The PXE server [what you call "proxyDHCP"] sees the DHCP transaction (because it's broadcast) and then repeats the DHCP response(s) with additional fields - using port 4011 as I recall. (that's the whole "Press F8" menu process) I've done that for over 20 years... on Linux. The more common method you're talking about needs the DHCP bootfile/server options to load a program designed to use the UNDI layer ("API"). There's a version of GRUB with support for the PXE/UNDI network layer. PXE is _not_ how laptops get repaired; not outside the factory, anyway. That's done by vendor specific recovery partitions, and/or UEFI "programs". (Your Dell slide doesn't have PXE in it anywhere.) Unless Intel has significantly updated the "standard", PXE does not directly understand HTTP/HTTPS, only TFTP and TCP/UDP. The program downloaded by TFTP can. (GRUB does) I don't have anything that understands a URL as a bootfile.

What seems to be confusing is that there is a separate, distinct place in DCHP message structure, that seems to also be capable of containing boot file name, - the "File field", mentioned in HP documentation and it is also mentioned in RFC 2131 without any reference to PXE functionality.

The music in the background doesn't improve the content. It just makes it harder to hear you speak.
