The A65 is interrated you could of gotten 256 , 512 or 1024 modules intergrated.
There is also slots to add more memory but if the intergrated one went bad your SOL.
Ther eis no wany to disable the onboard ram however if your good at soldering you can try to remove it and just put ram into the free slots. -- Email/MSN: Michael at hardwaregeeks.comAIM: MikeR35292
