@thread:
No go. This BPPC rev. 0 definitely doesn't work with Grex. I've tried using Voodoo 3 in every PCI slot, and the results were always the same. CGXMODE doesn't run, and there's no video output through Voodoo 3 when in early boot menu, or when in BPPC boot menu.
I've even made sure that the motherboard gets extra power through the floppy power connector, as well as the PPC card itself (+5V through the fan connector). P8 and P9 connectors are inserted directly to the Grex.
:-(
Back to mediator for me. :-) I'm not going to fool around with this anymore, as flashing the PPC card with different firmware back and forth ain't healty. I was curious to see if rev. 0 would really work, however it seems that it won't (at least not my card).
