[OT] DMA access from a non-bus master PCI device?

[romit dasgupta]

Hello,
           I have a PCI device that cannot be a PCI bus master (only a 
PCI target). For some reason it has a DMA controller. Since it can't be 
a bus master I can't initiate DMA transfers from this PCI device to 
system RAM.
My question is, can we use the motherboard's DMA controller to perform 
this transfer? In some of the documents that I got in the web 
(http://www.pcguide.com/ref/mbsys/res/dma/func.htm), it is mentioned 
that the 8237 DMA controller that comes with standard motherboard 
chipsets, can only be used for DMA transfers over the ISA bus.
Any comments are welcome.

Regards,
-Romit
