Once I saw a screenshot here at A.org, where OS 3.9 was just booted and there was 1900> kb of free chip ram left with backdrop of 256 colours and 1024x768 resolution. And using a A1200 for the job. I just wish I could find that pic again .
It's impossible to do this with native Amiga graphics. 1024 x 768 x 8 needs 768 kb of gfx memory. 2 MB - 768 kb = 1.25 MB. That's the absolute maximum you can get. But gfx is not the only thing which needs chip ram. There's also sound, floppy disk and all the stuff in the zero page. It's hardly possible to keep 1 MB free with this high screen resolution.
To have more free chip memory than that, you need a graphics card. The Indivision is not a graphics card. It does not come with its own graphics chips and memory. It just manipulates what the native gfx chips do.
