Windows Deployment Server and Multi/Uniprocessor

Posted on 2009-03-30
Last Modified: 2013-12-12
I have recently loaded a couple of XP images to our WDS server that were built on a uniprocessor machine. I have noticed that when trying to load these images to a multiprocessor machine they do not show up as an option. I think this microsoft article kind of explains what is going on. 

My question is, short of rebuiding these images from scratch on a multicore, how can I trick WDS to install these on those particular systems? I have already tried changing the processor in the BIOS temporarily but it throws up some kind of DHCP error when loading WDS. A complete and simplistic solution is key. Please help!!! Thanks in advance!

This isn't going to be possible because the HAL is different for multiprocessor systems.  Its more than just a few registery changes.

What if I loaded the image on the multiprocessor machine a different way and then did a non-destructive reinstall using the XP disks? Would this reset the HAL to multiprocessor?

Never tried that.  I'm really not sure if it would work or not.

You could try loading the image onto a machine with very similar hardware (except the processor type) then transfer the harddrive into the multi-processor machine. When it boots windows will recognize the new type processor and load the necessary files.
Like i said this will only work if the hardware is similar.

Oh and then you can re-image the machine

I think I found my answer and I will post so that others may find it easier than I have. If I load the single core images to a multicore machine and apply the following procedure it will bring the other processor back. I have tested it and it works!! I should then be able reseal and load this image up the WDS and then the multicore machines should be able to see it and use it. I have not tested the second part out but I do not see any possibility of failure. I will post back with the results as soon as I complete the procedure. Here is my find available on this link and I have posted the relvant part.

Option #1 - Hal / NToskrnl replacement
a. Make a directory called DUO on C:\
b. Copy halmacpi.dll (search your C:\ drive for this) to C:\DUO then rename it to hal.dll
c. Copy ntkrnlmp.exe (search your C:\ drive for this) to C:\DUO then rename it to ntoskrnl.exe
d. Make a batch file called go2core.cmd and put this in the file.

REN hal.dll hal.old
copy C:\Duo\hal.dll C:\windows\system32
REN ntoskrnl.exe ntoskrnl.old
copy C:\Duo\ntoskrnl.exe c:\windows\system32

e. Run Go2Core.cmd from C:\duo directory.
f. Reboot and you should now see two processors in Task manager
