Thanks for responding. I just wanted a confirmation though... I have this issue with WinPE5 booting, SCCM is set to prompt for password before imaging (we are paranoid...). In some cases, the keyboards will not work. It isn't consistent by model - we might image five of the same model and one will do it consistently. The only way we've found is to plug in an old Mac keyboard.
This fix of pointing to the older Intel driver... This is in the WinPE boot image you are referring to?
Regards.
