smbus \- System Management Bus controller driver
.SH DESCRIPTION
.sp
.LP
The \fBsmbus\fR driver is a I2C (Inter IC) nexus driver that allows the system
to communicate with various system      component chips. SMBus is a two-wire
control bus based on the I2C protocol through which systems can communicate
with various I2C devices connected to the bus.
