The physical frame buffer address(linear mode) lets me address pixels in = Truecolor and Hi color modes without much difficulty. However some cards may not support linear mode , ie operate in banked = modes only. I have difficulty in plotting pixels in 15 16 24 Bpp modes using banking .=20 Any VESA gurus here can point out some code which might be helpful in = solving above trouble. Pages providing information such as theoritical = knowhow about same may be helpful too. Thanks in advance for prompt = reply. Siddhartha.

Hi,
I was programming for VESA VBE2.0 and i got a problem.
The physical frame buffer address(linear mode) lets me address = pixels in=20 Truecolor and Hi color modes without much difficulty.
However some cards may not support linear mode , ie operate in = banked=20 modes only. I have difficulty in plotting pixels in  15 = 16 24=20 Bpp
modes using banking .
Any VESA gurus here can point out some code which might be helpful = in=20 solving above trouble. Pages providing information such as theoritical = knowhow=20 about same may be helpful too. Thanks in advance for prompt reply.
