Enable memory remapping in the BIOS.

Ya, I've read that on other forums too but my bios doesn't have that option.
Also, the bios settings haven't changed since I had Vista64 working with the
4GB of memory...

Vista tended to report the full memory, even when it couldn't actually use
the "hidden" memory on a machine. Win7 is actually telling you a more
accurate amount.

What does your Resource Monitor say about memory usage?
Start - Accessories - System Tools - Resource Monitor - memory tab.

K, I found a solution... weird though...

I was using MSCONFIG to make sure windows started with all four cpu cores
(i.e. msconfig / Boot / Advanced Options / number of processors).

I guess I also selected use max memory option as well.

In windows Resource Monitor 1026 MB was set aside for "Hardware Reserved"

I unselected the "use max memory" and now Win7 reports the full memory and
the Hardware Reserved dropped to zero.

Hope it helps someone else.
