Memory problem

My brother has a AXPER XP-P4VM533 motherboard and I'm having problems with
it recognizing the 256MB memory card. When I bring up the CMOS information
prior to booting into Windows it identifies the total memory as 224MB. It
seems to be missing 32MB.

My question:
Is this as indication that the memory card is bad?
Is this an issue with the motherboard?
Is the wrong memory card being used?

What I've tried to do:
I've removed the memory card a couple of time and reseated it. I've
also cleaned the contacts.

The manual for the mother board identifies the following memory as being
compatible:
2 184pin DDR DIMM sockets, supports up to 2GB DRAM
Support DDR266/DDR200 DIMM
Support only 2.5V DDR SDRAM

The current chip has the following information written on it:
87L5HDL0-1LDG
256MB 32x64 PC2100 CL2.5

Do not panic. This is completely normal. In all likelihood, you have
onboard graphics which are using 32MB of your system memory.

RAM never shows as the sum-total of the MB you have installed. Various bits
of hardware use the RAM, BIOS just shows you what's "left."

Is your brother using the on board video, which uses main memory? In
which case it very likely is using the missing 32 MB.

Chipset is VIA P4M266A & VT8235(CE)

The integrated graphics use up some of the system memory, and
that is where the missing 32MB is going.

Test with memtest86+ from memtest.org , as a way to determine
if the memory is good. You can either prepare a test floppy, or
there is an .iso image as well, for making a test CD. Two
passes is enough to determine whether the memory is error
free or not.

Follow that, with the Prime95 torture test (mersenne.org). Prime95
is available for Windows or for Linux. It carries out a calculation
with a known answer, and is a good check that the processor, the
Northbridge, and the memory are in good working order.
