to display 8-bit bmp
u took my question otherwise.........
What i mean is.....u need to enter some value in AL register before interrupting to use ROM-BIOS function.
for 320x200 256 color....u need to enter 0x13 in AL register to set VGA for that........
But I want to display an image in 800x600 256 mode.......Then what should I enter in AL register.
If u had the code to display bmp.....plz send it to me.
That is the best you can do using INT 10h BIOS services (as far as I know).
You should look into using Vesa Bios Extensions (VBE).
If you want code to display bitmap then this should help you.
I don't know about getting into 800 x 600 mode.
