Use this, because the device name is eth0.

(Unless you're using devfs.)

You don't need to specify both. It's broken down to that degree to allow different drivers to be loaded for, say, the mixer, the PCM audio output, the sequencer device... > 3--How is it that sound-slot-0 and char-major-14-3 are associated to the > same module???????? char-major-14-3 is generic, just determined by the major (and optional minor) device number, and sound-slot-0 is how soundcore tries to load (via kmod) the driver module. > 4--How does one know that char-major-14 is associated to soundcore rather > than dmasound_pmac or dmasound_core or something else????????????????? Because char major 14 is reserved for sound devices? > 5--How do I know that I need i2c-keywest????????????????????????????? For a Pismo, you don't. It's needed for PowerBook G4s and iBooks with DACA, Tumbler/Texas, and Snapper audio chips, where the mixer control is done via an I2C bus. -- Derrik Pates [EMAIL PROTECTED] [EMAIL PROTECTED]
