debug.exe - VGA Display screen address - 0xB800:0000
« on: November 06, 2011, 04:24:14 pm »
The VGA display screen address begins with 0xB800:0. The first byte to display the ASCII character and the next byte to store its background and foreground color.

To test this change, type debug.exe on the command prompt:

-e B800:0
B800:0000   20.61    07.4F

The inputs 61 to display character 'a' on the first row and first column of the screen and 4F for RED color background and WHITE color foreground.
