I was particularly touchy since I was still feeling rather triumphant!

For sure, in my quest for more info it seemed as if there was a veil of mystery drawn around the subject. I even got the feeling at MS they didn't really understand it!

Having done some Hardware Abstraction Layer (hence HAL) type work for other OSs I know just how tricky that stuff can get. With the crazy amount of possible different combinations of devices I'm surprised sometimes that PCs work at all. lol.

OK - I'd love to hear more about your opinion on the different (are there more than uni- and multi- processor?) Let's have a look... I guess you mean this one

Device Manager does not permit the change from a Non-ACPI HAL to an ACPI HAL.

Anyway, when I read this
http://support.microsoft.com/kb/299340/ it didn't seem as if hacking the HAL was such a good idea...
As far as I'm concerned, what I did was only uninstall and then re-install what was there before (I assume) - I was just hoping that it would do some system discovery stuff on installation and that maybe it would correctly detect the ACPI/APM options this time. Seems I was right, in part, maybe. Certainly the Device Manager is reporting the same as before.
