Once again thanks both of you for all your help.
Going the way TCS has described I recon that I have a VIA694 with a model number AWRDACPI if that means anything
I've tried looking on the goldenram.com but I cant seem to find anything on the searches.
Happy Y2k4 to you both!!
P.S. is 512MB the best to go for when using XP, bearing in mind that I'm probabily going to be using MSFSACOF quite a bit this year
Cheers again!
