Cannot use parallel port under 2.6.4
I have been unable to get my parallel port to work under kernel 2.6.4, slackware 9.1. I have searched all of the forums for help without any success. I have tried compiling lp, parport and portport_pc as modules and as part of the kernel, nothing has worked. If I boot with the default 2.4.3 kernel the port is set up perfectly and my printer works fine. I am using a HP Deskjet 722c winprinter with a pnm2ppa driver.
Is there something else i should be compiling into the kernel?
I have also tried all of the different parallel port settings in the BIOS.
Any help will be greatly appreciated!!
