This driver is a module for pcmcia-cs-2.9.10 and above. It implements the necessary interface for HiSax (which became part of the standard kernel since 2.0.31) to access the teles S0 ISDN card. Note that 2.1 kernels are broken with respect to teles pcmcia (someone mixed up some io calculations). So unpatched versions will not work! See http://home.wtal.de/petig/ for more (recent) information. If you need additional information or feel that something important is missing you might vote for that (mailto:christof.petig@wtal.de). Patched versions of HiSax support an automatic configuration scheme; #define NEW_HISAX might work for you, which passes irq, protocol, io to hisax. A patch is only available for 2.1.98 so far ... 2.1.120+ and 2.0.35 versions are coming. Unless this is ready, please copy the port and irq mapping reported on syslog (/var/adm/syslog, F10 on SuSE). Transfer them into /etc/conf.modules. I'm working on a better support, please feel free to ask for it (increases priority). Sorry this patch hasn't made it's way into the standard package, so please apply it ( cd pcmcia-cs-3.x.y ; patch -s
