Windows 7 & RAM

I have 2 machines that are both running Windows 7.

Comp 1: Intel Core 2 T7200 2ghz, toshiba satellite (laptop)

Comp 2: Intel Core 2 T7500 2.2ghz, sony vaio (all-in-one)

Both are running, Windows7, 4GB ddr2 ram, 64-bit o/s, all drivers and updates

Toshiba see 4.00GB (3.00 useable)
Sony see 4.00GB

So a super dumb question--why is this? Does it matter that the toshibe sees only 3GB/ I thought that was a 32-bit o/s quirk!?
 
Besides the shared gfx issue, the motherboard/chipset must support more than 4GB of addressing space plus memory remapping in order to fully use 4GB RAM. A 64bit edition is not always the entire solution.

Hmm, so stupid question--how can I check this?

When I ran XP and Vista they both showed 4GB on 64bit!

What specs do you need to know?
 
Pretty self explanatory. Bios - Memory Remapping - Disable or enable.

Ok...I don't know where to find that on this Toshiba laptop!

also, why did this laptop see 4GB under Vista 64? I never had to change things before?

EDIT:, I went into the BIOS and it's so basic--and has nothing called remapping..etc
