PCI pin layout

[Christopher]

Hi!

Anyone know where I might be able to find a PCI pin layout?

I want to build an inexpensive card to plug into my PC. I'd like to
address the card by a specific address location and pass data using
the 32-bit PCI slot.

Any thoughts are most appreciated.

Thanks

What interface hardware are you going to use? PCI is difficult to work with,
even if you buy off-the-shelf interface chips. All the PCB tracks have to be
the correct length, for instance.

Christopher,

PCI does not work like ISA - I don't believe that you are able to directly
access it by 'specific address location'.

There is a specification for PCI at the PCI working group... not sure where
their site is - a Google search should turn up a good site. I would
recommend it for pinouts and trace length specifications - if you're going
to do it right.

You'll be as well to use something like a PLX PCI9052, it saves a lot of
work and you can be (reasonably) sure that it works (the caveat is
because some PCs, notably Compaqs, have been known to screw up on this).
But if you only want to use it yourself, you can take a note of where
the plug-and-play puts things, and choose a spare address. I really
think using the 9052 is going to be just as easy. They'll even give you
a schematic and a layout if you ask them nicely.
