I know people get really tired of hearing this debate, but I'd like to make my position as clear as possible once and for all.
First and foremost:
The reason the LPC exists on the Xbox motherboard is because the TSOP is soldered to the board blank, and programmed via the lpc port later in the manufacturing process. When the TSOP is blank, the xbox then looks to the LPC for a bios image to boot. This is because a pre-programmed rom is more expensive than a blank eeprom (TSOP in this case). It also allowed Microsoft to more easily update the bios image in new Xboxes for whatever reason.
So we know that they would have to retool the LPC programming device if they disconnected some LPC points. This new tool would need to be incredibly fine because the point it needs to make contact with is no longer a nice big pad.
Since nobody can find a 1.5, this retooling would have been for just a handful of motherboards. So they would have gone through this expense of retooling for such a tiny amount of boards it wouldn't have made any sense.
Next, what exactly did the alleged 1.5 board prevent? It ONLY would slow down mod chip installation. I say slow down because any knucklehead with a DMM could figure out how to get it working again. It does absolutely nothing to stop soft modding or TSOP flashing. Why would Microsoft go to such an expense to stop only one method of modding the Xbox? I don't doubt that people have found LPC points that show no continuity. This could be because of the very programmer I mentioned at the beginning of this post. It could be due to trace rot. It could be due to operator error in measuring the components. Whatever the reason for a person measuring this situation, I don't believe it was a particular version of motherboards that Microsoft intended to put out.
We saw with the 1.6, where it DID come with a pre-programmed rom (so no TSOP) on the board that they could finally disconnect the LPC. That's why we have to rebuild it there. It is perfectly consistent. It stops TSOP mods. It stops modchips for noobs. It required a new bios that supported the new video encoder. I think they believed they could use updates on game disks and Xbox Live to patch the softmods. So they thought they had all the bases covered with 1.6.
I got my information from the Xbox-Linux Project. They published an article on Xbox Security which I preserved on this site.
"Now other people found out that, if the ﬂash chip is completely missing, the Xbox wants to read from a (non-existant) ROM chip connected to the (serial) LPC bus. This is of course because of the manufac- turing process: As it has been explained before, the ﬂash chip gets programmed in-system, the ﬁrst time they are turned on, using an external LPC ROM chip. Modchip makers soon developed chips that only needed 9 wires and connected to the LPC bus. It was enough to ground the data line D0 to make the Xbox think that ﬂash memory is empty.
Lots of these “cheapermods” appeared, as they only consisted of a single serial ﬂash memory chip. They could be installed within minutes, especially after some companies started shipping chips that used pogo pins, so that no soldering was required.
Some groups wrote applications like boot menus that made it possible to copy games to hard disk and run them from there. Patched Xbox kernels ap- peared that supported bigger hard disks. Making the Xbox run copies from DVD-R or hard disk as well as homebrew applications written with the ofﬁcial Xbox SDK was now easy."

It's under the "Modchips" heading.
A week ago I've picked up an Original Xbox from a flea market. The seller said that it works just fine but he can't get the disc tray to open and that there is a game inside. Of course none of this was true The Xbox could not even start: after pressing the power button, it turned on and then immediately off and repeated this 3 times...and then it seemed to stay on but the LED was just blinking red and there was no picture. It is a 1.6. After narrowing down the issue to the motherboard itself (I have unplugged both the HDD and the DVD drive and tried another power supply), I decided to just replace the motherboard with another 1.6 I had for spare. I have never tried this motherboard before and it has (a fake?) Duo X2 modchip soldered in. Surprisingly, the Xbox powered on without any issues after that but it now gave me an error code.
I know that HDDs are married to the motherboard so it made sense to me that this motherboard will not work with the original HDD of another Xbox. I've grabbed a 80GB (IDE) maxtor HDD I had and replaced the HDD. After putting in the the HeXeN 2019 disc, it recognized the new HDD and I was able to format it and install a dashboard. The Xbox no longer gave me an error code however there was only a black screen after the boot animation. (The Evox logo showed up on the upper left corner though)
I have used Rocky5's "Xbox Softmodding Tool Extras Disc" (1.1.7) to install the UnleashX dashboard, MS dashboard and some tools and it was finally booting up as normal. Right when I thought I am done ressurecting this Xbox, I had noticed something: It could only play burned copies of games. I have tried 3 different, original games and all are recognized however as soon as I want to launch them it gives a black screen and returns to the dashboard. Even after clearing the CACHE.
I thought maybe I could see some kind of error message if I launch the game from the MS Dashboard (which could maybe indicate a DVD drive issue) however the "Xbox Dashboard" item is missing from the "Application" menu. I am sure that I have installed the MS dashboard from Rocky5's extras disc but I've re-installed it just to be sure but still there was no option to launch the MS dashboard. By this time I have also noticed that there was no sound when scrolling through the menus of UnleashX even though I have also installed audio from the extras disc.
I had an idea that maybe the custom BIOS was too old or something (It had Evox M8+ 1.6 137+ according to the dashboard) so I have even updated the BIOS from the HeXen disc to a 256K evoX but it changed nothing.
I had one final thing that came to my mind: Maybe mixing the HeXeN install with Rocky5's extras disc was a bad idea. I had an original Xbox HDD which had a proper softmod installed using only Rocky5's Softmodding Tools and the HDD key nulled out so I thought I could simply clone this HDD with Chimp (by setting the Maxtor drive to slave). It worked however I got the same black screen after the boot animation as the HeXeN disc. I went ahead and installed UnleashX and the MS dashboard from the extras disc again. The Xbox booted up just fine but there is still no sound in UnleashX and no option to launch the MS dashboard...
What I am doing wrong?
I would assume that not able to launch original games might have to do something with the (Samsung) DVD drive but the missing MS dashboard clearly should have nothing to do with this. Maybe this is something that has to do with the (Duo X2) modchip installed on this motherboard?

Why do people like the hexen disk?
I have a version 1.4 xbox with a Open Xenium with a Ind-5004.67 bios and a X2-5035.137 bios and that's set as the default boot bios
For the test install I used a 2 tb hard drive
1st load the hexen 2020 disk and cold boot.
2nd use option 3 (TSOP Flashed,Modchiped)
3rd use Option 3.5 (Chipped)
4th option 3.5.3 (New disk NTSC) now enter a password (friggen stupid idea) now sit back and watch it install all sorts of files and folders including a folder called ''Delete Me "". Let Xbpartitioner 1.3 do it job and now I can reboot the Xbox without Hexen and it boots to unleash dash.
Ok I wan't XBMC so load Hexen disk and use Install Applications then install XBMC, More files been installed and more Delete Me folder files!
I also wanted XBMC4Gamers so I added that as as Application and the same Delete Me stuff.
Reboot the Xbox without the Hexen disk and unleash opens now it now has a XBMC icon so press A to load XBMC and nothing it comes back to the unleash dash but it works if I run it from the apps folder and so does XBMC4Gamers.
Now I really want XBMC4Gamers as the default dash so I loaded up the Hexen disk and used the option 5 Dashboard tools
Then switch Switch dashboards option 5.1 and there is no XBMC4Gamers but XBMC will do for now so I set that as the default dash on E drive(that's also where I installed XBMC and XBMC4Gamers)
And now reboot the Xbox without the Hexen Disk and it now locks up after the boot animation.
And using the IND bios is the same it locks up at the white IND bios screen.
Ok so lets load the hexen disk again and set the dash back to Unleash and reboot it now will boot to Unleash again.
The Hexen disk is now out on the road some where after it was as a frisbee out the door.
So now I load Slayer 2.7 and complete new large drive install and reboot
FTP XBMC4Gamers to E drive and also FTP Xbpartitioner 1.3 to E drive
Open file explorer to run Xbpartitioner 1.3 and Format F and G drives to 926.78 gb each
FTP back to the Xbox and edit the X2config file on E drive to set xbmc4gamers on the E drive as the 1st boot dash
Now reboot the Xbox and now I have XBMC4Gamers as the default dash and can set about copying me games and the like across.
And this folks is why I love Hexen.
Soft modding is like masturbating, It gets the job done but it's nothing like the real thing.
