>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?

 Bruce,
 
 This is a good idea, and it has been discussed before, somewhere but I
 am not sure where exactly.  Anyway, the bus_dma information in the ISA
 section is old.
 
 I have plans to write a bus_dma chapter for the Developer's Handbook ,but
 not anytime soon as I am busy with College and what not.  If you want,
 you can write a chapter for the Developer's Handbook which documents the
 bus_dma subsyste -- you can get all the information you need for this
 from the bus_dma(9) manual page.
 
 Regards,
