I have this very strange problem on my A4000 with a CS-PPC / GREX4000 ....
When using chipset software (a whdload game or something that uses chipset display) I get corruption and eventually a lockup. in whdload games it is more apparent, as there is gradual corruption, color changes and then a crash, in apps there are flickering pixels, or the lower part of the screen changes colors or luminance...
the only way to "fix" this, is by either removing the voodoo card or deleting the powerpc.library in libs: ....
the voodoo display is flawless, no crashes whatsoever and 3D works fine. and the ppc is OK too, as it works after long time of testing... it is a phase5 233mhz csppc, never overclocked... and I use a 250W ATX psu on an Elbox adapter... I tried the following with no results:
1. cleaned chipram simm socket and tried 4 different 2MB simms
2. used a 2nd arxon scandoubler
3. used a 2nd voodoo card, this time a slower 2000 model
4. removed all other pci cards and tried the voodoo on another slot
5. tried several other psu's
6. tried the 16.1b1 powerpc.library, it allowed me to use for more time whdload games without the eventual lock-up
7. tried lowering and inserted waitstates in 68k ram access in csppc menu
8. tried a 2nd 4000 mobo and a 2nd p5 csppc
nothing helped (except the new powerpc.library but still it locks)
is there an incompatibillity with g-rex+p5 csppc? I flashed the g-rex bios... any special setting on the warpOS prefs ? The DCE csppc worked fine (until ppc died that is) and never had to worry for things like that...
what should I try next? any ideas? :-? :-? :-?
EDIT: as the grex+voodoo+aga combo works perfect _without_ the powerpc library (I assume then the ppc chip is not used at all) is there a possibility that some g-rex traces used by the ppc part are broken and that leads to this kind of corruption/crash?
:-?
