It’s a little known fact (outside the Asus Eee PC forum) that after you install a RAM upgrade you have to go into the BIOS and, well, look at it and it will properly report 2048 or whatever of RAM, and then Save and Exit (F10) before it will recognize that 2nd gig of sweet, sweet RAM.
It has something to do with Boot Booster, which sounds like a exercise gimmick.
But you can’t find this information on Google because the first 5 pages are all reviews and/or sales and apparently there isn’t a lot of people reporting this on other forums.
