HIPPI 128c2ecf20Sopenharmony_ci can run over copper (25m) or fiber (300m on multi-mode or 10km on 138c2ecf20Sopenharmony_ci single-mode). HIPPI networks are commonly used for clusters and to 148c2ecf20Sopenharmony_ci connect to super computers. If you are connected to a HIPPI network 158c2ecf20Sopenharmony_ci and have a HIPPI network card in your computer that you want to use 168c2ecf20Sopenharmony_ci under Linux, say Y here (you must also remember to enable the driver 178c2ecf20Sopenharmony_ci for your HIPPI card below). Most people will say N here. 188c2ecf20Sopenharmony_ci 198c2ecf20Sopenharmony_ciif HIPPI 208c2ecf20Sopenharmony_ci 218c2ecf20Sopenharmony_ciconfig ROADRUNNER 228c2ecf20Sopenharmony_ci tristate "Essential RoadRunner HIPPI PCI adapter support" 238c2ecf20Sopenharmony_ci depends on PCI 248c2ecf20Sopenharmony_ci help 258c2ecf20Sopenharmony_ci Say Y here if this is your PCI HIPPI network card. 268c2ecf20Sopenharmony_ci 278c2ecf20Sopenharmony_ci To compile this driver as a module, choose M here: the module 288c2ecf20Sopenharmony_ci will be called rrunner.
