Windows free vs checked edition problems

[hash3d]

I've managed to make a checked/debug version of windows xp by integrating a checked version of service pack 2 into free edition of windows XP sp1a. It works ok, gives some "invalid handle" info in WinDBG.
My driver installs OK on free edition, but on this made-checked version i get "PipCallDriverAddDevice: Unable to reference driver \ Driver\... " error with status "couldn't start driver"..
Is it posible? i mean that it works on a free edition and doesn't on checked? or this way of obtaining the checked version isn't good after all?

To the best of my knowledge (it has been a while), you need to be consistent with using checked-build vs. normal builds. I have always applied checked service-packs to checked baseline installs, and have never had a problem.

Differences in compiler/linker settings can easily make structures different, etc. The range of potential problems is enormous.

There's a problem that i'm not able to get a "normal" checked version. I can't afford msdn subscription. And i'm still pretty stuck on previous questions in another topic.
