I changed strategies: Testdisk is a self-booting cd image that MAY be able to recover your partition
If that is not your desire, meaning you do not care about the old windows xp installation and are happy with re-installing windows, then we proceed with that.
However, it makes me VERY UNCOMFORTABLE you not knowing the revision of your motherboard.
Do you have the original box? It would be on there. It will be printed on the motheraboard somewhere with the model number, often between the PCI slots.
It appears that both revision use the same driver so it is probably ok to just go ahead
Simply go back to post 8, copy the files as described and insert the floppy in your drive....boot the computer, hit f6 when it asks, and windows setup should find the driver.
