Frame Buffer Size and Location

[coolpurplefan]

I have a
SATA Western Digital hard drive (WD3200AAJS),
a SATA Pioneer DVD-RW (DVR-115D),
an AMD Athlon X2 5400+,
Asus 8800GS (384MB),
OCZ "Special Ops" RAM 2GB (OCZ2SOE8002GK),
BIOS 2701
WinXP Pro SP3 32-bit
and I'd like to know about the following (on my Asus M3A78-EM):

UMA Frame Buffer Size [Auto]
What setting would be more ideal?

Surround View [Auto]
is grayed out, should it be on disabled?

Frame Buffer Location [Above 4G]
I read if you have less than 2GB of RAM, you should set that to [Below 4G], is this correct?
