Hi,

Depending on the hardware, the actual range of addresses reserved can be
from .5 to 1.3GB, leaving anywhere from 2.7-3.5GB of memory addresses. It's
not hard and fast. All depends on the system, and the OP could very well be
on the low end of this.

Some of your 4GB of address space must be used to access such things
as your video RAM and BIOS. What's left over is used for physical RAM.

Go away little man.
Or at least keep these kinds of comments to yourself. Your reply
borders on being classified as spam.
I know that I am breaking my own rule here ... But, just don't reply
if you can't answer the OP's question.
And as posted above, [url]http://members.cox.net/slatteryt/RAM.html[/url] is a
good page to start.
