Graphic card drivers problem in Powerbook rev 1&2

[Dehuti]

I was using Powerbook 500Mhz for some time, running OS9.2 and 10.2 installed on. But I changed my hardware to Powerbook 550Mhz (becouse of DVD-RW drive) and here's where my problems arrise. After HD-change system works great, but each attempt of running Quake 3 or Wolfenstain on new machine brings me error message (no GL support). I noticed that there's difference between graphic cards in both models, 500 has 8MB Ati Rage (RageM4 in Profiiler), 550 has 16MB card (RageM6). My question is - how to manually change drivers to proper version without reinstalling both OSs?

Anyone? RageM6 is in fact Radeon (comes with 550MHZ Model) but it's not recignized in my system properly. You can find out what's installed only by ATY codes. Any attempt of running OpenGL-dependent software brings message: "Could not initialize OpenGL', but I have allready Installed Radeon Driver +OpenGL 1.2.1

You dont have a radeon. That is probably the problem. It is an ATi Rage Mobility. I am almost positive that Ati does not have unified driver archeitecture also....

I'm quite possitive it's Radeon. I looked up specification, ATY codes, other users experiences - it is. But.. how to get it work wit OpenGL?
