You were right, the board uses only 128MB of video ram, I get maximum 87mb of used video ram, and the normal ram is filled a lot, I reached having only 9mb of free ram, then,if I load another picture, the system locks.
That's what I meant. You could have believed me in the first place, you know ;)
Set aside this question, why the system prefers to fill normal ram instead of video ram when loading pictures?
Video memory is pretty volatile. Once it is needed, existing bitmap data might be cast out. Now, copying FROM video memory is mostly much slower than copying TO video memory, so the data is always kept in main memory and copied to video memory only for displaying.

I have seen that the 9200se 256agp has a lot of soldered jumpers, 8 in the back and 11 on the front side. possibly one or more of them would let me use all the 256Mb, as on the pci version sold by elbox, but who could know the meaning of these jumpers???? thy are a bit too many!
