Anyway, I hope you kept the original file (it was renamed to sio.c.orig). Put it back where it came from. You can get a patched version of sio.c at ftp://ftp.lemis.com/pub/sio.c-2.2.6. Make sure to rename it to /usr/src/sys/i386/isa/sio.c before building a new kernel. > Also, I found out something else. sio0 ans sio2 were not > responding.. so I went to toshiba site, looked up specs for TECRA > CDT 550. It said modem is on pci bus. Interesting.
