Graphics in x86 assembly

Post by sparkie »

Do any of you know how to draw graphics in assembly without the presense of a OS? You know, like in a boot loader.

In real mode you can use 13h mode, you can set this mode by interrupt 10h.
Then in A000 you have got graphic card buffer.
in protected mode it's more difficult, i think that the best is turn computer into V86 and then do it like in real mode (rmode isn't very bad :P)
