I don't really understand how reflashing the bios solved the problem but glad to hear it. You will definitely benefit from the 2G as oppose to 1G. I have an Asus 1002HA on which I installed Win7 even before ASUS made some bios and driver updates. Since that time I've updated the bios and installed some of the ASUS releases for my model. Oh yes, am using Win7 Ultimate on the ASUS. Be sure to get hold of a Win 7 Recovery CD and put it onto a UFD so you are prepared for any disasters.
