On the screenshots, I can see that you have big Radeon in one slot and x1950 in another one, did it mean that dual-booting works for mos/os4? I mean, I want to have morphos install also on my x5k, but want to keep Polaris card for os4, so is it works if you just add "ATi Radeon X1950 PRO Extreme", and then both oses can work, just morphos one set up for x1950 and os4 one for Polaris?
