Review of Linux Compatibility

The Delock PCI card 89004 extends the PC by 2 additional serial and by 1 parallel port.

The PCI card is recognized by the Linux kernel in the following way:

07:00.0 Communication controller: NetMos Technology PCI 9835 Multi-I/O Controller (rev 01)
	Subsystem: LSI Logic / Symbios Logic Device 0012
	Flags: medium devsel, IRQ 16
	I/O ports at ec00 [size=8]
	I/O ports at e880 [size=8]
	I/O ports at e800 [size=8]
	I/O ports at e480 [size=8]
	I/O ports at e400 [size=8]
	I/O ports at e080 [size=16]
	Kernel modules: parport_serial

In order to use access the card, the kernel module parport_pc has to be loaded together with the IO ports and the interrupt of the card. It is possible to provide several parameters at once, e.g.:

/sbin/modprobe parport_pc io=0x378,0xc000,0xc800 irq=7,11

If the initialization of the Linux kernel module parport_pc was successful, the additional parallel port is listed at /proc/interrupts:

  7:          1   IO-APIC-edge      parport0
  8:          2   IO-APIC-edge      rtc
  9:          0   IO-APIC-fasteoi   acpi
 11:          0   IO-APIC-edge      parport1

The IO ports can be found at /proc/ioports

0378-037a : parport0
b400-b402 : parport3
b403-b407 : parport3
c000-c002 : parport1
c010-c012 : parport2

To automatically load the module at system boot a .conf file has to be created in the directory /etc/modprobe.d/ (e.g. in Ubuntu 12.10)

alias parport_lowlevel parport_pc
options parport_pc io=0x378,0xc000,0xc800 irq=7,11
