CONFIG_PARPORT If you want to use devices connected to your machine's parallel port (the connector at the computer with 25 holes), e.g. printer, ZIP drive, PLIP link (Parallel Line Internet Protocol is mainly used to create a mini network by connecting the parallel ports of two local machines) etc., then you need to say Y here; please read <file:Documentation/parport.txt> and <file:drivers/parport/BUGS-parport>. For extensive information about drivers for many devices attaching to the parallel port see <http://www.torque.net/linux-pp.html> on the WWW. It is possible to share a single parallel port among several devices and it is safe to compile all the corresponding drivers into the kernel. If you want to compile parallel port support as a module ( = code which can be inserted in and removed from the running kernel whenever you want), say M here and read <file:Documentation/modules.txt>. The module will be called parport.o. If you have more than one parallel port and want to specify which port and IRQ to be used by this driver at module load time, take a look at <file:Documentation/parport.txt>. If unsure, say Y. CONFIG_PARPORT_PC You should say Y here if you have a PC-style parallel port. All IBM PC compatible computers and some Alphas have PC-style parallel ports. This code is also available as a module. If you want to compile it as a module ( = code which can be inserted in and removed from the running kernel whenever you want), say M here and read <file:Documentation/modules.txt>. The module will be called parport_pc.o. If unsure, say Y. CONFIG_PARPORT_SERIAL This adds support for multi-IO PCI cards that have parallel and serial ports. You should say Y or M here. If you say M, the module will be called parport_serial.o. CONFIG_PARPORT_PC_FIFO Many parallel port chipsets provide hardware that can speed up printing. Say Y here if you want to take advantage of that. As well as actually having a FIFO, or DMA capability, the kernel will need to know which IRQ the parallel port has. By default, parallel port interrupts will not be used, and so neither will the FIFO. See <file:Documentation/parport.txt> to find out how to specify which IRQ/DMA to use. CONFIG_PARPORT_PC_SUPERIO Saying Y here enables some probes for Super-IO chipsets in order to find out things like base addresses, IRQ lines and DMA channels. It is safe to say N. CONFIG_PARPORT_PC_PCMCIA Say Y here if you need PCMCIA support for your PC-style parallel ports. If unsure, say N. CONFIG_PARPORT_OTHER Say Y here if you want to be able to load driver modules to support other non-standard types of parallel ports. This causes a performance loss, so most people say N. CONFIG_PARPORT_AMIGA Say Y here if you need support for the parallel port hardware on Amiga machines. This code is also available as a module (say M), called parport_amiga.o. If in doubt, saying N is the safe plan. CONFIG_PARPORT_ATARI Say Y here if you need support for the parallel port hardware on Atari machines. This code is also available as a module (say M), called parport_atari.o. If in doubt, saying N is the safe plan. CONFIG_PARPORT_MFC3 Say Y here if you need parallel port support for the MFC3 card. This code is also available as a module (say M), called parport_mfc3.o. If in doubt, saying N is the safe plan. CONFIG_PARPORT_1284 If you have a printer that supports status readback or device ID, or want to use a device that uses enhanced parallel port transfer modes such as EPP and ECP, say Y here to enable advanced IEEE 1284 transfer modes. Also say Y if you want device ID information to appear in /proc/sys/dev/parport/*/autoprobe*. It is safe to say N. CONFIG_PARPORT_SUNBPP This driver provides support for the bidirectional parallel port found on many Sun machines. Note that many of the newer Ultras actually have pc style hardware instead. CONFIG_PARPORT_GSC Say Y here to build in low-level parallel-support for PC-style hardware integrated in the LASI-Controller (on the GSC Bus) for HP-PARISC workstations.
