Thanks -
Yah you're right about those being startup entries in the registry - but I use msconfig to manipulate them (btw - MSCONFIG is available for Win2k and XP on the web - do a search for it or I'll send you a copy). I've also suspected a Win98 driver may have caused this (see notes below on old USB Digital Camera that was attempted/installed). Anyway, MSCONFIG was really useful in allowing me to eliminate much old Win98 stuff (SYSTEM.ini, WIN.ini settings etc) as the root of the problem.
Thanks for your comments - but this is a tough one because the only trail left is a cryptic tag entry in \winnt\msbtlog.txt from when the failed device install occrred during boot. That long hex code (PID?) is the only hope of matching up the culprit with whatever software it needs. I've even done web searches for it, obviously no luck.
don't wanna sound snooty, but I"ll give a few more details in hopes of getting something tangible - I've spent a lot of time on this - to the tune of uninstalling and reinstalling, in various orders, all the components in my system.
I strongly suspect this is a software driver snafu with ATI - its related to their Capture driver and the actual Radeon display driver. I've ordered their installation exactly as described in their README file (Capture, THEN Display) - but they warn against this EXACT condition if you instll these in the incorrect order. So (I doubt it), but maybe I did install them in the incorrect order years ago, but I've long since uninstalled/reinstalled everything hundreds of times since. This should be something that can be remedied.
So that's how I *know* this is being caused by their (specifically these two)drivers. Why else would they warn against this exact condition iccuring?
fyi - I've followed ATI's All-In-Wonder Radeon tech notes to the letter, and also those I found at:

I've also gone through Microsoft's technote on this condition (Unknown Devices found at boot) - there's nothing in Computer Management that indicates a problem device or process etc. etc.
These seem to be software devices. But it wants a driver for them that doesn't exist - they're apparently created/installed as some sort of interaction between the TV-Capture driver and the Display driver. I've installed anything they could be asking for. You can only abort the Wizard - and then they become two "unknown devices" in DM. They don't provide anything tangible in Device Manager - disabling them only causes them to be re-detected again at boot.
- tried the USB thing....disabled USB altogether - even turned it off in the BIOS. Nothing helped. Interesting point though that this all started around the time that old Digital Camera software was installed. This is why I think the only other possobility here is that these "software devices" were Win98 driver components installed by this old Dig. Camera software. I've done searches for old vxd's though and deleted everything even remotely suspicious.
Anyway, tangent.
Does anybody know where in the Registry such software devices might be residing? I've used RegCleanr, RegClean, Norton SystemWorks, and my own limited Regedit tweaking to eliminate this - unsuccessfully.
It also could be the existence of certain files, but these procedures I've listed above have listed many files - all of which I've located, dumped (and perhaps reinstalled).
btw - ATI won't help because my card is too old (5 years?). So spread the good news about ATI ok? Here's a special toast to them.
