The ports on the IBM pc/xt/at/.... are ways to connect peripherals to the 
proccessor, in a different location than the memory. If you want information
regarding the ports, try looking at the PETER NORTON Programmers Reference Manual. (I think that's the name). You can find there a list of ports and their
connections. If you want Information regarding the contents of the ports, and how
to use them, look for the specific information you need in the correct books. for
example, look at some INTEL reference manuals, to get info about the DMA, PIC, 
and so on.
		hope this helps. Eran Davidov.
