At least 4-5 people have tried to do Zorro III (with and without DMA) to PCI bridges in the past. All are AFAIK closed source.

I wonder how much the system would speed up if we were able to use our PCI videocards with 'real' DMA.

The problem with SATA is getting the SERDES phy. I dont think anyone sells them separately (although I do have some Phy test chips).

FPGA's with SERDES I/O are super expensive I think.

It might be possible to use an Oxsemi U931DS which has a DMA capable SRAM bus. It would be slow though.. but perhaps not as slow as ZorroIII ;-)

I would be interested to know if the Deneb drivers & Poseidon will fit in a Kickflash... Bootable USB drives?
