In theory, a peripheral on an EISA bus should be able to use a DMA handler
to access any main memory that isn't locked by the CPU.  And in theory, a
mulit-threaded OS takes advantage of this capability.

In practice, does OS/2 do this on an EISA bus?  Or an MCA bus, for that
matter?

How is it done?  Is it done invisibly by a device driver, or does the
application programmer have control over the process?  Feel free to be
technical; I'm soon to become an OS/2 programmer.
