Comparison of NTLDR from Longhorn and XP Project abandoned:(

[danfoshizzle]

So, been playing the last few days, seems that there is not too much of a difference in the ntldr of xp and the ntldr of longhorn, longhorn being vistas "beta", its a good looking beast and performance is closely matched to xp and nowhere near the memory hog that vista is, so I am going to to try and rewrite the OS and get this booting on the joggler, Drivers will need rewriting I should imagine, not something I have done before but going to give a shot anyway! then I will try updating as far as i can see how far i get before NT6's bootmgr takes over lol

Longhorn itself is alot different in use than either XP or vista, with performance close to that of server 2003, the theme in my opinion would suit the joggler very well, all seems very "touchy" to me!

This is the closest I think we are getting to nt6 on the joggler, unless someone far more talented than me comes and proves me wrong(please do!)













That is how it looks sitting in my VM, not too bad! that is at the joggler resolution aswell iirc!

How did you get hold of that, I've been looking but didn't find it
Looks good by the way!

http://winworldpc.com/library_m1.shtml thats where I collected all my betas, whistler included, which might also get the joggler treatment as its closer in memory footprint to windows 2000

Thanks for the link, might try one of those myself

I cant seem to get a graphics driver or touch driver to work, project abandoned unfortunately

Did you get as far as it booting on the Joggler? Is it just the drivers holding things back? Does Longhorn use the NT6 driver model? Questions, questions!!

[danfoshizzle]

Its drivers, and the screen does not fit as erics patched vga.sys works but seems as though its pushing out 800x600, which is odd to say the least!

Hmmm. I wonder if a startup batchfile running nircmd will do the trick? http://www.nirsoft.net/utils/nircmd2.html

Code: Select all

nircmd.exe setdisplay 800 480 32

I'm downloading the most recent build on the site linked to above, build 6.0.5259.0. I hope that's one I can get working, at least to the point that you have. I'm interested to see how the NTLDR from Longhorn and XP compare, too. Googled and found http://sanbarrow.com/phpBB2/viewtopic.php?t=1696 and read that NTLDR is comprised of 2 parts. The 16bit part sets up the environment and then chains the 32bit part which reads the various config files and begins booting the OS. I've yet to look at the source of the NTLDR that we use on the Joggler as I'm no coder, so I don't know if we can transplant the bootloader from one to the other.

Edit: yeah, should have gotten 5048...... redownloading.

Not sure if people have seen this or not, but it looks interesting:

Is the method we use for Windows on the Joggler at the moment?

[Mevi]

no, that is for 64bit versions of W7. Only 64bit W7 supports UEFI which won't run on the joggler's HW. Wrong version of EFI on the Joggler too.

Eric Huang modified the source code from XOM (XP on Mac) and gave us XOJ (XP on Joggler).

[danfoshizzle]

Yeah, that was the reasoning behind trying longhorn, as it would have been as close to nt6 as we can get at the moment. May restart project longhorn in the next couple of months!
