Great - thanks for confirming.
Unfortunately though I have now fallen at the next hurdle. Sorry to keep hassling you guys! But it seems the procedure is different for XP.
So...
I have right clicked
Video Controller and chosen Update Driver.
When Windows asks if it can connect to Windows Update, I have said No.
The next screen asks whether I want to "Install the SW automatically" or "Install from a specific location". I have chosen the latter.
I am then presented with this screen:
Presumably browsing is the right option, so I browse for the folder created in previous steps, but when I select it the OK button is still greyed out. As I delve into the subfolders, the OK button remains greyed out.
There are some folders in the Drivers folder but most of these leave the OK button greyed. In fact, only two folders will allow me to hit OK: XP6A_INF and XP_INF:
Am I barking up the wrong tree completely? Is it a case of the procedure not being possible in XP?
Any help most gratefully received at this stage.
Cheers
