>Description:
	bus_dma is the architecture independant DMA API, which applies both
	to PCI and ISA on x86 architectures.  However, it is explained only
	in the section about ISA resource allocation in the developers handbook.	Developers looking for information about DMA for PCI cards miss this 
	very useful information.  It should possibly be put into its own topic.	
>How-To-Repeat:
	read http://www.freebsd.org/doc/en/books/developers-handbook/isa-driver-busmem.html
>Fix:

	Create a topic documenting bus_dma?
