I think you've missed the point: the BIOS knows what kind of parallel port
chip is in use, and where its configuration registers are hidden. I think
David was hoping to find a way to avoid having to write chip specific
drivers for all the different parallel ports out there ...
David: some BIOSes no longer offer EPP mode as a setup option even when the
chip supports it. Do we have any evidence that the EPP-BIOS would work on
such motherboards ?
