What makes you think that whatever BIOS update you have...is going to change anything you want changed? Did you read the description of the BIOS update?
Generally (very) speaking...it's only the Dell/Gateway/HP, etc. systems...which may need BIOS updates to increase functionality of a system.
The operating system (XP and beyond) is what determines the size of hard drives which can be accommodated by a system...it's been that way since SP1 was released.
Unless you have a system that predates that release, there should be no question about hard drive size which the system can/does support. Do a Google for "BIOS support for 1TB drives" and see how many hits you get.
IMO, it's always a bad idea...to use the largest hard drive...for a Windows partition.
My XP Windows partitions are 20GB and my Win 7 RC1 partition is 40GB for O/S, critical updates and installed programs.
I have 4GB of DDR2 installed (XP Home, 32-bit) and my system sees all of it. You need to understand...an awful lot of persons express opinions on the Internet concerning things of which they only have 2d-hand info. And they are often wrong.
Your motherboard specs will tell you the maximum amount of RAM it can support. If you want to double-check, you can login at www.crucial.com and give them the pertinent data for your board...and they'll look up the number of slots, largest module those slots can accommodate, etc.
