Re: Sensors on Asus P2B-F?

[Paul Goyette <paul%whooppee.com@localhost>]

Mostly, you just have to know.

The iic manpage documents the I2C_SCAN option and tells you why we don't 
autoscan the i2c bus.  Even scanning the bus simply tells you which 
addresses respond;  there is in general no way to know for sure what is
at each address.  Not like PCI bus where there is a standardized Vendor 
and Product code.

Some addresses are 'reserved', such as 0x50 thru 0x57 for spdmem(4). 
But mostly you just have to know what device is where.
