Parport Address

I am trying to get started with EMC2. I use a Dell GX240 pc. The BIOS gives 378h as the parallel port address. When I try to use Stepconf to configure I get an error: Parport error bad port address '378h'.When I use 0x0378 as the address, Stepconf works,but when I try to test an axis, the motor doesn't turn. Is it OK to use the address in the form 0x0378, or does that cause a disconnect between the software and hardware? Are the output signals actually reaching the parallel port? Thanks for your help.
