Installation Guide for PCI Parallel Ports
CHIP SET: MCs9835cv
This installation guide describes the procedure to install the Nm9735CV in the PCI parallel ports in Linux platform.
Linux kernel provide a 'parport' code to support parallel port (/dev/lp0, /dev/lp1,
/dev/lp2). This code provides the ability to share one port between multiple devices.
And it is loadable when kernel is running.
The 'parport' code is split into two parts : generic (which deals with port sharing)
and architecture-dependent eg. X86, SPARC. (which deals with actually using the port).
Thus, please take the following steps to install 'parport' module!
Check the on-board parallel port's hardware resources
Most likely each motherboard has a built-in parallel port. And its hardware resources
are settable with BIOS utility.
Enter the command more /proc/pci
The response is similar to the following
Bus 0, Device 11, function 0:
Serial controller : Unknown vendor Unknown device (rev 01).
Vendor id=9710, Device id=9705
Device id=9735
Device id=9805
Device id=9815
Device id=9835
Device id=9855
Medium devsel. Fast back-to-back capable. IRQ 11

Install 'parport' module
To load the generic 'parport' code
Type insmod parport.o
To load the architecture-dependent code to tell 'parport' code
insmod parport_pc.o io=0x378,0xc000,0xc800
irq=7, irq=11, none
or
insmod parport_pc.o io=0x378,0xc000,0xc800
irq=7,11,none
You have three PC-style ports, one at 0x378 with IRQ 7, one at
0xc000 with IRQ11, one at 0xc800 with no IRQ.
Check the attached printer device [optional]
Once the architecture-dependent part of the paraport code is loaded into the kernel.
You could enter the following command
insmod parport_probe.o
To check any attached devices and log a message similar to
parport0: Printer, epson
Then /dev/lp0, /dev/lp1 and /dev/lp2 are ready for service
