8/16    What is "PCI-based interfaces"?  Thanks.
        \_ Probably someone referring to AGP, the video slot standard
           which Intel is pushing.  AGP is apparently very similar to
           PCI, but it uses some extra tricks to get more perf.  --PeterM
           \_ AGP is directly related to PCI.  It is a design that allows
           \_ AGP isn't directly related to PCI.  It is a design that
allows
              videa cards direct access to main memory and forcing video
              cards to rely on main memory than a local video buffer.
              This actually has the unusual effect of making some video
              operations slower while making others that are heavily
              memory intensive much faster.
        \_ peripherals compenent interconnect.  It's the name of the
           really complicated bus architecture that was designed to
           replace the old ISA, EISA, Microchannel, and Vesa Local bus.
           You can tell if a slot in your computer is PCI if it white,
           small, and has a lot of pins (i know that sounds kind of
           generic and vague).  ISA slots tend to be black, larger, and
           have less pin count.
           ISA          8 bit   8 mhz
           EISA         16 bit  8 mhz
           Microchannel 16 bit  10 mhz
           VESA         32+ bit 33+ mhz (3 devices max on local bus)
           PCI          32+ bit 33+ mhz
