I tried to find vesa docs but all in vain :-[ . I could find only vbe docs. Is there any other way to get around bios and to access hardware directly ??? . Some one write some good tutor on vesa programming without using bios ( is it possible )
Yes of course abt LFB also

Re:vesa info needed
Hi,
Sorry to say, but VESA is just a BIOS standard. Yes, it's meant for video cards, but the VESA compliant (doesn't have to be) video card BIOS just 'translates' the call with the right parameters to video card specific code (which means, setting the right value at the I/O ports of the videocard).
In short; VESA is just a BIOS standard. Now you could do a few things to get video graphics working in your OS. More info can be found at the osfaq
Good luck & hth,
DennisCGc.
