What architectures does DragonFly support?
DragonFly is currently targeted at the x86 line of processors; it should
work on 386 and up, though a 386 is certainly not recommended.  Work is
also being done on support for the new 64-bit processors from AMD. 
There are currently no plans for support of other processor types.

However, support for Sparc or PowerPC or other systems is possible in
the future.  If you plan to submit code to the DragonFly project, please
keep this in mind.
