Default base address of Busmastering DMA

Post by markq »

Hello, I want to enable DMA mode however, according to the articles I need to enumerate all PCI device in the configuration space to find out the base address of the Bus Master. Is there a default address or do I have to enumerate?

Enumerating PCI devices is reasonably easy, and you'll need to do it at some point - I'd just go ahead and get it done.
