some info at http://driver-backup.com/driver_detail/?driver_id=56704 on FCDABIOS (2003) device Enumerator but I'm still not sure what device it relates to. If you click on System devices on that web page, the next page shows a long list. If you eventually notice something that doesn't seem to work right, that may be your clue to this mystery.
You might try letting Device Manager search the internet for a driver for that item. I'd bet chances are slim it will find a driver to resolve it but still worth a try.
Thanks soybean for your interest. And yes, Device Manager kept offering to search the web to find the correct driver but could find nothing. I followed your link and download the driver for FCDABIOS (2003) device EnumeratorOO, which btw was on the first page. But, it wasn't very fruitful, couldn't find driver or ? in that download. Didn't see anything either that I could relate to in that long list. Anyway, what I did then was go to the FCDABIOS (2003) device EnumeratorOO file in System Devices on my PC(the file that looked OK) and found that the manufacturer is Farstone. I went to the Farstone site and downloaded the driver (rather huge), from there. Their instructions are to "Add Driver" to Pre-Windows Recovery Manager ,which doesn't appear to be anywhere on my system.
If I understand this properly, Farstone is used for Virtual Drive / Back Ups, which I never use anyway. Assuming that I'm correct, if it gives me anymore concerns I can always delete Virtual Drive from Add/Remove programs.
btw, haven't been bothered with that pop up since early yesterday. Maybe it's gone
Thanks again. overthehill
