Congratulations on getting the music back, Ken.
It is a fairly complicated process and one which fills me with trepidation each time I've done it. Luckily, it worked fine when I did it, but the laptop I used is even older than yours. I used a Dell Inspiron 1525 with an Intel Core 2 Duo processor, running Windows Vista! I used a 1m USB cable and a 5m Ethernet cable which has to reach the network switch in the next room.
I'm just about to acquire my mother-in-law's laptop, which is newer, but I wonder if I'll enjoy the same success next time I need to do a firmware update.
