- 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.
