eeepc

Hi all, I have replaced the original slow 16gig ssd with a faster Supertalent 32gig ssd in my eeepc 900. Now the onboard 4gig ssd can't be found by the system anymore. I have the latest 1006 bios. When i remove the supertalent ssd the onboard 4 gig ssd magically reappears. Think it has to do...
