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
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.
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.

You were born to be a professor, you got people watching you from Europe
greetings from Greece!!
Εκτιμώ τους θεατές μας από την Ελλάδα!
In Depth Knowledge…..helps a lot to understand the concept thank You …..
Thanks for watching!
Thanks a lot. We use a lot PXE with our students
Thanks for watching! Students need to use and understand this technology!
Thank you for this very informative video! 🙏🙋♂️ Greatings from Germany…
Ich freue mich über unsere Zuschauer aus Deutschland!
Wow Sir, great video! respect for the speaker 👌
Thanks for watching!

Great comment, sound very interesting for a video. I will consider!

Appreciate the great comments and feedback, they are welcome on this channel. Thanks for watching!
My first thought was "why DHCP" if I have my IP address in NVRAM. I just assumed PXE docs with talk about what he does when trying to find addresses.
Great video!
Appreciate your support!!!!
The music in the background doesn't improve the content. It just makes it harder to hear you speak.
Thanks for the feedback, I try and pull the volume down so it gives transition not interfere. Thanks for watching!
Thanks Techsavvy Production
