ataport.sys and fltmgr.sys corrupt or missing

[gregorsamsa11]

I have a WinPE 2.0 build that I've been testing on a variety of hardware. On a few specific machines, WinPE fails to boot with the following error messages (paraphrase):

Corrupt or missing ataport.sys

Corrupt or missing fltmgr.sys

I do not think these files are actually corrupt or missing. I suspect that this may be caused by the use of some unsupported XP drivers in my build. The problem is that trial and error has shown that these drivers solve issues on other machines, so removing them is problematic.

Does anyone have any insight into this issue, beyond "using XP drivers in Vista is bad news?"

Thanks,

David

The number one cause for a PE to fail to load or operate properly is bad memory. I always run memtest on machines that don't work with the PE as my first step. I have found some motherboards do not like the PE at all, but that was a long time ago.
