Windows 7: Windows 7 (On Mac Pro) Memory Unusable

Windows 7 (On Mac Pro) Memory Unusable

Hey guys!

I have been doing some research on google and some other sites still no luck. I have a Mac Pro computer with Windows 7 installed on it. I just installed Win 7 on it using the bootcamp option with Mac. It is only showing 1.99 GB of Ram useable out of 6GB. I am not aware of how I could get to the BIOS on the Mac, if there is one. I am a windows user but have tried the Mac world for a while so I'm blinded. Any help to fix this?

Windows 7 32 bit. Omg that should of been the first thing I looked at since windows has a 32bit 4gig cut off. When installing I choose the x86 version. Should I have choose the regular x64? How do I change it from a 32bit to 64bit?

You will need to re-install Windows 7 (x64) to get the 64bit. However (x86) should see at least 4GB of RAM. Does BootCamp have a setting for how much memory an OS can use? I have never used BootCamp so I don't know how it works.
