 | 8 | 	---help--- | 
 | 9 | 	  PLIP (Parallel Line Internet Protocol) is used to create a | 
 | 10 | 	  reasonably fast mini network consisting of two (or, rarely, more) | 
 | 11 | 	  local machines.  A PLIP link from a Linux box is a popular means to | 
 | 12 | 	  install a Linux distribution on a machine which doesn't have a | 
 | 13 | 	  CD-ROM drive (a minimal system has to be transferred with floppies | 
 | 14 | 	  first). The kernels on both machines need to have this PLIP option | 
 | 15 | 	  enabled for this to work. | 
 | 16 |  | 
 | 17 | 	  The PLIP driver has two modes, mode 0 and mode 1.  The parallel | 
 | 18 | 	  ports (the connectors at the computers with 25 holes) are connected | 
 | 19 | 	  with "null printer" or "Turbo Laplink" cables which can transmit 4 | 
 | 20 | 	  bits at a time (mode 0) or with special PLIP cables, to be used on | 
 | 21 | 	  bidirectional parallel ports only, which can transmit 8 bits at a | 
 | 22 | 	  time (mode 1); you can find the wiring of these cables in | 
 | 23 | 	  <file:Documentation/networking/PLIP.txt>.  The cables can be up to | 
 | 24 | 	  15m long.  Mode 0 works also if one of the machines runs DOS/Windows | 
 | 25 | 	  and has some PLIP software installed, e.g. the Crynwr PLIP packet | 
 | 26 | 	  driver (<http://oak.oakland.edu/simtel.net/msdos/pktdrvr-pre.html>) | 
 | 27 | 	  and winsock or NCSA's telnet. | 
 | 28 |  | 
 | 29 | 	  If you want to use PLIP, say Y and read the PLIP mini-HOWTO as well | 
 | 30 | 	  as the NET-3-HOWTO, both available from | 
 | 31 | 	  <http://www.tldp.org/docs.html#howto>.  Note that the PLIP | 
 | 32 | 	  protocol has been changed and this PLIP driver won't work together | 
 | 33 | 	  with the PLIP support in Linux versions 1.0.x.  This option enlarges | 
 | 34 | 	  your kernel by about 8 KB. | 
 | 35 |  | 
 | 36 | 	  To compile this driver as a module, choose M here. The module | 
 | 37 | 	  will be called plip. If unsure, say Y or M, in case you buy | 
 | 38 | 	  a laptop later. |
