Custom drivers

My graphics cards drivers (RAGE 128 Pro) only support up to openGL 1.2. However this is using the most up to date drivers. I have heard some talk of unofficial drivers which allow more recent versions of openGL to run on legacy cards like my own. But I can’t find any though google. So is there anyway to use more recent versions of openGL (1.4 especially) on my card?

No
You could try the software renderer, Mesa
