Well, IIRC, the BIOS scans 'some' memory range for any ROM presence (like network, video cards), and, if found, runs them. Also, I think the video card is responsible for the int 10h. Possibly you can have a look at linuxbios and their freevga implementation[1], or the vbe standard[2]. Obviously, I may be totally wrong. 8) Nicolas [1] http://wiki.linuxbios.org/data/vgabios/ [2] http://www.vesa.org/public/VBE/vbe3.pdf ------------------------------------------------------- SF.Net email is sponsored by: Discover Easy Linux Migration Strategies from IBM.
