But this didn't happen under Bios 1101 so your answer is still not directed towards my question.

I understand I need a 64bit OS to see all the ram--that's not the question. If the previous bios I was using DID NOT appropriate any memory, and the OS I am using now "sees" 3GB of ram BEFORE I flashed to 1506 without appropriating 1152MBs of ram---how can I get that appropriated ram back?

This is a BIOS/Motherboard question--not and OS question.
