- I don't have the same model GVP as you but I'm pretty sure that if your RAM is
- on the GVP board the important thing to do is to configure it all as extended
- rather than auto-config memory. The documentation that came with your GVP will
- tell you how to do this (yes, with those tiny little jumpers that are so easy
- to drop).
