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
