Please can you read through and vote on the following proposition for changes to the board structure by clicking here.
ISTR (perhaps trag can elucidate) that there is some issue with cards with PCI-PCI bridges and the 6400/6500. That said, my TAM had a Sonnet combo USB-FW card in it and the TAM is basically a 6500, so I can recommend one of those.
There exits Sonnet specific nvramrc patches for Sonnet card PCI-PCI Bridge problems that you can download.
A nvramrc patch for general PCI-PCI bridges in Gazelle (6500, TAM) based Power Macs is discussed at #232
I don't know if Alchemy (6400) has the same problem. If it does then a similar patch could be created to handle that.
I was away for a while. The 6400/6500 actually isn't my specialty. The above referenced thread is probably the best reference.
I did extensive testing of PCI-PCI Bridges in the Umax S900 clone and can talk about the problems and exceptions at length, but that's not very helpful to someone with a 6400 or 6500.
Bought a Sonnet Tango 2.0 : it was not cheap, but it was new! Nice purple card, works great!
Previously tried an Adaptec DuoConnect AUA-3020, but it was only half working (the FireWire half). And prior to that I had bought (real cheap) a Belkin F5U508, but with a VIA chipset there was no way it would work! (narrator: it didn’t work at all)
So, the Sonnet Tango 2.0 is the way to go for an hassle free USB & FireWire upgrade for the 6400!
