I am not sure how to translate the hex memory ranges into megabytes.

Me either, but since I know I'll be corrected if wrong...

The second value has six more Fs. That translates into decimal
16777215. Then maybe you multiply that by 32 bits to get
536870880. Looks like 512 MB would be closer than 1 GB?

Correction... "32 bytes"

I don't think the Frame Buffer setting will show at all with the 210 installed, only when it is out and you're running
on the onboard chip.

GPU-Z is a different program than CPU-Z; it's for video cards/chipsets only.

I'm sorry I misled you about disabling the onboard video. I think I still had my old M2NPV-VM MB on my mind when I
posted that; it had the separate options of enabling/disabling.

To reference another user's allocations, I couldn't find a Device
Manager picture for Geforce 210, so I grabbed the first Linux
one I could find.

The three mappings, appear to match your mapping, in terms of size.
A 16MB, a 32MB, and a 256MB segment. So it's not even reporting as
a 512MB card (as the 256MB segment would be 512MB, if it was a 512MB
card). If could be, that the card is "TurboCache", and dynamically
allocates additional memory from system memory. But that would not
affect the "free" memory reported by the OS. It doesn't explain why
it reports as 1GB.

When I compare your map to my map, it looks like your computer
is avoiding the top-most 512MB, and I don't see a device listed
that corresponds to that range. That can happen, if a fixed
allocation is given to the built-in graphics. Some of your
hardware devices needing bus space, are at 0xDE, and 0xE0 to 0xFF
would be 512MB of space.

As near as I can determine, 512MB is just being wasted. And I
can't tell exactly why. Either a BIOS bug, or still related
to the IGP (integrated graphics).

It's already in bytes.

Besides, you're not looking at the main buffer. That's at C0000000
and it's 256mb.

Windows 7 calculator in programmer mode can deal with the math for you
quite easily.

I see three buffers on there:
256mb at C0000000
32mb at DC000000
16mb at DF000000

(I'm not counting the little one in low memory that exists to emulate
an old-fashioned VGA.)

Have you considered that the video card might actually _have_ 1024mb of
memory installed? Mistakes do happen and I'm sure that the person at the
factory isn't being paid the big bucks for sticking labels on them as they
pass on the assembly line. Of course the real answer is to pop the heatsink
and determine what memory chips are installed and to do the math.

BTW, with XP you are unlikely to seem much more than 3gB installed memory
if you have 4gB of SIMMs installed.

Here's another way:
