Now, who can explain the difference between Expanded and Extended memory?
PS Samuria, sorry but "anything else had to be extended" isn't correct as there is also expanded memory. Not to mention the "reserved" memory between 640KB and 1MB.....
See http://en.wikipedia.org/wiki/Expanded_memory if you are interested.

People dont know what they have missed as once you had low level formated you had to then format again and you had to set up the interleave for the drive to get the best from it. Bring back Quemm and Desqview were you could load 10 programs before windows had started

It had 512KB memory which I remember upgrading to 640 by buying the chips and putting them in myself. 6 chips - 4 each of 32K and 2 smaller ones for parity.
It's also got a pair of revised BIOS chips that I think I had blown to support larger capacity hard disk types up to 80MB I think.
The motherboard says NCR '86 (that's 1986).
IIRC it came from a server running Pick for a telesales team system. When it was retired in the early 90's I "upgraded" it to run DOS.

Anyhow, anybody any idea where this memory has gone, or is it just a case of how its displayed in this older laptop?

I may be wrong, but it's how I always understood those cards to work.
Hope that helps,

Somewhere in the BIOS you can normally set how much main memory is to be used for graphics but on some systems it is a fixed value which cannot be changed. Once set (or preset by the system), this is all it is able to use and does not 'adjust' as it goes on which is what I think you are saying.
Note to OP: don't confuse the video memory allocation from the AGP aperature size value shown in the BIOS as they are toally different things. The AGP aperature can be different to the actual ram used by the graphics chip.
It does look like the mobo uses a fixed 16MB of main memory for graphics hence why windows reports 496MB.

Although it is somewhat unusual in my experience.
