It was not enough for get my USB NEC board working on M5484LITE.
Normally you put the 3V3 in short-circuit (ATX alim are protected) because some pins are wired on 5V and 3V3 here on the CTPCI (like the M5484LITE) .
So you must cut this pins (no security), and put a pin for output buffers voltage by default to 5V to 3V3 (the NEC has this pin, the Radeon I don't know). It's not easy.
Else you send 5V signals on the bus, sure it's not a problem for the PLX, but tomorow if you put another board who is 3V3 only and you forgot your modifications on the 1st board, you destroy the new board.
The problem is not the final choice of PCI 3V3 himself, the problem is that lot of guys has boards in 'wait state' since 2005 where Rodolphe said PCI is 5V-3V3 compatible.
Actually my 2nd USB board for the CTPCI is 5V only.... So I'am not happy.
Didier.

What's the anti-troll code?
That's your personal code to be able to add comments and messages on the dhs.nu site.
Don't have a code or forgot it? Fix it here.
