The HARDWARE still works, you just have to override what Linux is told the port can, and can't, do. Writing 0x80 to the ioport 0x402 higher than the parallel port base address (0x378) turns on the EPP mode, despite what Linux believes the port can do. The ppmc driver would do this except that Linux has told it that address doesn't exist. So, I have a separate program that does this without checking, and Don has demonstrated that it does work. My pcisetup program, at : http://pico-systems.com/codes/pcisetup.c
will do that. Compile with cc -o pcisetup pcisetup.c or you can get the executable at http://pico-systems.com/codes/pcisetup but you will have to set it to executable after downloading it. This program needs to be run with super-user privileges.
