Sound cards will not work in the third slot. Install any DMA-able cards in the first two slots (Sound or 100MBit ethernet or TV-Card), the Voodoo should not occupy a DMA slot, it does *NOT* support BusMastering.

Wierdly, so far I've heard of a lot of stuff that should not work on a certain PPC cards and yet worked when I tried. ;-) No, 95% of BPPC cards are not Rev.0, most 160MHz ones are iirc and some of the 200MHz ones. All the 240MHz boards I came across are rev.2.

As far as I know, the omissions in the Rev.0 board PCI logic are DMA related. I've never heard of a BVPPC not working at all (while they are supposed to), and if that works, the Voodoo 3 should too, DMA might or might not work, apart from the DMA stuff, the PCI bridge on the 1200 version is virtually identical to the BVPPC one afaik, the 4k version is different (includes full dma on all slots and parity support). Stormlord: if you're getting a signal on the early startup, the G-Rex *is* working. People, don't forget that many BPPC cards might be damaged. My own card sustained some damage when I did something pretty stupid that fried my mobo and PSU and found that PCI stuff with a dynamic PCI address (G-Rex stuff for example) don't work on PPC OSes anymore, the board returns an incorrect base address, while it works fine with static ones, or in 68k mode. (Yes, WarpOS/PowerUP stuff *do* work)
