>Hi, I'm trying to install an additional lpt using PCI parallel port card NetMos Nm9805CV. >The 4.7 kernel reports: >pci0: <unknown card> (vendor=0x9710, dev=0x9805) at 20.0 irq 11 >How can I use it? >Thanks. Well, it works on Linux, what about FreeBSD? This installation guide describes the procedure to install the Nm9705,Nm9735CV, Nm9805CV, Nm9715CV, Nm9835CV, Nm9755CV 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 Board with Nm9805CV part I/O at 0xc000 [0xc001] printer port I/O at 0xc400 [0xc401] ECP/EPP config registers I/O at 0xc800 [0xc801] not used I/O at 0xd000 [0xd001] not used I/O at 0xd400 [0xd401] not used I/O at 0xd800 [0xd801] not used 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 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
