could not load OpenGL subsystem

i have been trying to run quake III, but in vain. it says"could not load OpenGL subsystem".
i have a pentium III,(933),128ram,…etc, running windows ME.

i did search through on net, and was adviced to change a content( dva=0 to ;dva=0 ) on the win.ini file. i have searched through win.ini file and there is no such content.

if you have any answers pls notify at pramod_s_pillai @ yahoo.com

thanx a lot
