| 37 | * The low level operations for the various display memory organizations are | |||
| 38 | * now in separate source files. | |||
| 39 | * | |||
| 40 | * Currently the following organizations are supported: | |||
| 41 | * | |||
| 42 | * o afb Amiga bitplanes | |||
| 43 | * o cfb{2,4,8,16,24,32} Packed pixels | |||
| 44 | * o ilbm Amiga interleaved bitplanes | |||
| 45 | * o iplan2p[248] Atari interleaved bitplanes | |||
| 46 | * o mfb Monochrome | |||
| 47 | * o vga VGA characters/attributes | |||
| 48 | * | |||
| 49 | * To do: | |||
| 50 | * | |||
| 51 | * - Implement 16 plane mode (iplan2p16) | |||
