Thanks for the hint on "Translate", I hadn't realized the page was in German (hadn't bothered to visit it before).
I believe here's a misunderstanding happening.
The author of the website (as can be seen on the page About / Ich ("me")), is named Christoph Woergi (which is likely true given the domain name).
He doesn't claim credit for "LukeOS", only for the first of the three "OS" downloads.
http://woergi.is-a-geek.org/src/asm/os/ ... uke_os.asm reads "LukeOS V0.02 (c) Luke Bowes, All rights reserved.
www.lukeos.u13.biz". (The domain being unavailable.)
So I guess you're barking up the wrong tree here - the website author seems to have gotten that "LukeOS" somewhere and put it up as an example of ASM code in action. I guess a friendly e-mail might do the trick, and you'll have "LukeOS" dropped in favor of "DexOS"...
