Hi Guys, I have some simple question here,that i hope u guys can easily solve. I want to initialise my display in 640*480*24 mode i.e VBE 112 h using this function. setmode() { union REGS r; r.x.ax=0x4f00; r.x.bx=0x112; int86(0x10,&r,&r); } How will i make sure that my card is set to VBE mode 112 ? After this i want to write to display memory directly my RGB data which is 8 bits each to display a pixel. Say my display memory is initialised at 0xA0000000L and I have RGB Data with me corresponding to a pixel then how can write this to display memory to glow the pixel.? Please give your expert comments Seetaram
