Follow the steps outlined above to set up 640x480 (8x16 font) "text mode" first. After that, use the following code snippet: |
|||
mov ax, 1123h ; 8x8 chars in graphics mode |
|||
mov bl, 0 ; Row = 0 (don't ask cause I don't know) |
|||
int 10h ; BIOS video interrupt |
|||
You should have 80x60 text mode in a 640x480 environment. Note that I haven't tested it (I'm writing it away from my dev box) on either emulated hardware or real hardware. So be careful. |

Text in 640x480 16-colour graphics mode
VGA video mode 12h is a 640x480 resolution, in which (with a little tweaking) can be used with your string printing function. All you have to do is add a mov bh,07h to allow regular coloured printing in graphics mode. At the moment, the cursor is disabled. You must find a way to eliminate it or do up a function specifically for printing in graphics mode.
80x60 text mode
As far as I can tell, there is no way to do this with standard VGA modes. If anyone has done this, please tell by emailing me at blasterman95 _AT_ gmail _DOT_ com or by PM'ing me on the forums! Thanks!
