The manual calls for the printer port to be set to Auto or Bidirectional, my bios does not seem to have an option like this.
I have run the parallel port in 3BC/IRQ7 and 278/IRQ5, both have the same effect.
Iv run it in SPP mode, EPP/SPP mode, ECP/EPP mode (That one would not even talk with the gameboy so I didn't try ECP only)
My systems running windows 95, I don't have the chipset patch installed, im not sure if that would effect it. Having a bit of trouble finding the drivers.
EDIT, testing again with ECP/EPP, The port address thing got changed and I didn't notice!
EDIT 2: No effect
EDIT 3: Tested again on windows 98, no effect
