As Bochs has evolved, so has the BGA. Five versions of the BGA have existed, of which 0xB0C4 is the current version (as of 2008, Bochs version 2.3.5). The main features of each version: |

[TODO] |
|||
* 0xB0C0 - setting X and Y resolution and bit depth (8 BPP only), banked mode |
|||
* 0xB0C1 - virtual width and height, X and Y offset |
|||
* 0xB0C2 - 15, 16, 24 and 32 BPP modes, support for linear frame buffer, support for retaining memory contents on mode switching |
|||
* 0xB0C3 - support for getting capabilities, support for using 8 bit DAC |
|||
* 0xB0C4 - [TODO: check and describe] |
