I have a 240GB SSD that I installed XP, then Win 7 on a Gateway desktop. Nice little dual boot setup.

Now Im trying to do another dual boot onto this HP x64 system. Not so easy.

Its an Optima PNY 480GB SSD. I guess XP doesnt support TRIM. But I have made it work before. Maybe the controller was more friendly on the Gateway than it is on this HP?
