That worked a treat and iss very much appreciated. I've burned it to CD and put in in the box with all the other firmware etc. that relates to this machine.
I think I am veyr nearly there but I think I still have one remaining problem. When I was initially trying to get the machine running, I loaded the Intel XHCI USB drivers and my keyboad, mouse and everything else conected to USB ports stopped working. Fortunately, on my earlier experiences, I had created a restore point so I re-booted into Safe Mode and reverted back to that and everything then came back to life.
I had originally downloaded the drivers from the Intel web site so, thinking I had inadvertently downloaded the wrong ones, I went to the MSI site (it's an MSI MOBO) and downloaded from here: https://www.msi.com/...-driver&Win7 64
Unfortunately, the outcome was the same and I'm curently awaiitng a return to the same restorei point and be able to use my mouse and keyboarrd again.
Any suggestions? If i wasn't for the fact that I back up quite large volumes of data on external USB 3 HDDs I wouldn't worry about it.
Any suggestions? I'm really, really sorry this has turned into something of an epic.
