Hello,
No need to post pics on your board. I understand exactly what you are facing.
This is your board and if you want to hard solder the jumpers feel free to experiment. However, keep this in mind, there are times that the jumpers aren't available for some other reason such as the board failing QA under higher front side bus speeds. Still, don't let that stop you as there are more reasons to remove the jumpers that are intended to keep you from over clocking and your board dates back to the days when Athlon and Intel did NOT want end users to over clock.
I DO want to know how you succeed at this as I am routing for you to succeed at this.
If you haven't started yet, I would only underscore the obvious, so my apologies in advance, use a low wattage soldering iron and a vacuum solder extractor (cheap parts at any Radio Shack) and ground your motherboard with clips out to a known to be grounded power outlet. Keep yourself grounded and work on a piece of cardboard. As I said, don't be offended if this seems redundant to you, others may be reading this out of interest and these procedures may be old hat to you but new to others.
The specs on the rest of your machine sound more than adequate to run not only a Socket A but drive a newer generation board as well, including PCIe vga cards as long as you have the supplemental power plug off your PS which I have no doubt you do.
So, if you would, keep me posted with your progress as I'm routing for you.
Regards,
Worldvet
Did I read your post wrong or have you reinstalled the Duron and booted up okay?
