Setting 640480 in ASM

[Matt Carpenter]

I realized that you cant use VESA to set the graphics mode in bochs (which I use to test my kernel), so I was wondering how to set the video mode in ASM without interrupts (using the out function). I'm aiming to get 640x480 res. with 256 color if possible

Can't you use another machine?

BTW I've tried Bochs and personally I thinks its not very good. If possible use another machine or try and get VMWare (even Windows XP runs on VMware but Unix X-Windows doesn't)

Bochs 1.4.1 supports VESA BIOS Extensions, but i have not yet tested it
I use Mondrake 8.2 in a vmware session (1024*768 24 bits depth color) to devellop my os, X-windows work in SVGA mode. Install vmware tools

When it comes to OS development, I use Bochs because of the nice builtin debugger. When it comes to running 2 OSes at once(like win95 and XP), I use VMWare.
