Yes, it's off-topic here, but anyway, what you see on the screen has to be in Chip-RAM. The Indivision is not a gfx card. The gfx card is still the AGA chipset and the chips can only access Chip-RAM. A screen of 1024x768x256 needs 768 KB gfx memory. With 8 colors it would need 288 KB. This memory must be in Chip-RAM. What can be moved into Fast-RAM by fblit and the like are those bitmaps which do not belong to the current display: Icons, hidden window parts and so on. But not the display itself.
