It actually doesn't require the BIOS to recognoze them, as it doesn't use LPT
port access, but uses direct I/O commands to the specified address.
(At least, that's how it worked through May-2000.)

Really, Linux is totally unaware that EMC is using these I/O devices. This
can cause some odd things to happen if you try to print while EMC is running.
Now, there is some BIOS interaction with my Parallel Port cards, whihc require
the BIOS to preset the mode of the parallel port chip on the motherboard to
the desired mode.
