Function Code: 0x4F00 Input: AX = 0x4F00 ES: DI Output: AX = 0x004F Please help with the implementation, or tell me which way to dig in order to program something higher. |

May we make random assumptions; like maybe you're talking about this BIOS function (and not a Linux system call or anything else), and that the function call worked (output ah = 0x00 = "success"), and that you're implementing code the uses VBE (and not implementing your own video card ROM)? If we can make these random assumptions; I still don't know what you need help with. Cheers, Brendan |
