This card doesn't probe correctly (at least BIOS versions 1.31, 1.36) And it locks the screen when you try to set with 4 meg ram set.
Dave, can we verify this in the lab? Mike, what sort of chipset does this card have on it? What sort of bus interface?
don't know if it related but I have problems with Redhat 6.0 and my Diamond Stealth 330 (RIVA 128). On installation any probing hangs the system. Only can get it to work with 16 bit 800x600 resolution which is a waste of a 19 inch MAG 800 Monitor, any higher resolutions Locks up the system
the rendition chipset (found in your Diamond Stealth II S220) has seen some work in the upcoming 3.3.5 errata release. please test the packages when they become available and re-open the bug if you continue to have problems.
