Finally we're getting somewhere.

The entire length of this thread I was assuming you were seeing 4GB at
POST.  You never stated otherwise, and ASSURED us the system had 4GB of
RAM.  It doesn't.  There are 4GB of DIMMs apparently installed, but
that's much different than the "system having 4GB".

What you have is mismatched memory.  Read the DIMM specs in that manual
PDF.  The board supports DDR 200/266, and supports single and double
sided DIMMs, BUT not in all density (DIMM size) and frequency combinations.

I.e. when all 4 slots are filled you must have a specific combination of
DIMM sizes and "sidedness" for the board to recognize and use all 4GB.
Read the manual and look at all 4 of those DIMMs and you'll identify the
problem.  The fix will require that you acquire some different memory,
either 2 or all 4 of the sticks.

Sorry Stan. Ain't so. There 4 identical Kingston 1GB modules all with the same model number. I very carefully purchased these after making sure that they were compatible with the motherboard and processor. Not the problem. To clarify, the BIOS lists 4, 1GB memory modules under the memory setup part of the BIOS setup screen. During the boot process the memory check is visible ratcheting up to 2.8 GB and stops. The boot process then continues. Yes I did swap the modules around and they all seemed to work fine. If I put 2 of them in the system the whole 2 GB is visible. I can do this in any combination.

I just noticed that the manual states that AGP and PCI memory needs are all above 3GB so I should have at least 3 GB.

I still appreciate the thought.
