I am certainly not a computer expert, but I understand that if the BIOS reserves a chunk of memory for integrated graphics this reduces the amount reported by the system: alternatively, if the graphics driver allocates memory during boot, the full amount of memory will be reported, but some of it has still been grabbed by the graphics so the net result is much the same - you have lost some system memory to video.
So my card (which is not integrated, of course) has 512 MB, total video memory is reported as 1919 MB and the extra 1407 MB comes from shared system memory.
In the old days I used an operating system called DR-DOS and this provided plenty of opportunities for memory tweaking, including adding more video memory. What I don't know - and would like to know - is whether in a 4 MB system which reports 3.25 Mb, any current OS can use the "missing" memory for video or anything else for that matter. It would be slower than dedicated video memory because of the system but, but then it already is - I just want better memory use.
