I take it that the software would switch between a BP and chunky screen memory system, but what identifies the different modes?
Is there an xbios or cookie jar setting or something along them lines?
Many thanks as always for any info.

Funnily enough, Ive just started reading that for the last few days (Im still on GEMDOS functions).
Ok guys, thanks for the help. It was just as I feared, with the same sort of hamstrung pin swapping like what the ST low/med<>high cable types have (i.e. requiring a switch).
So the chunky RGB is only good for PAL/15khz then? (And obviously faster than bitplaned modes for screen draw/blit operations?)
