In particular many Asus mainboards have SMBus pins. I've never seen anything advertised by them to connect to it... but I did hook up a scope to one of mine to confirm that it works. > Common Phil, I'm not that crazy! ;) If you consider that 1) I don't want > to sacrifice the brand new evaluation board Sean kindly sent to me 2) I > don't wan't to sacrifice my own computer hardware 3) I don't have tools > for doing electronics here 4) I'm not particularily competent when it > comes to soldering and 5) The evaluation board works through the > parallel port under Windows, so it has to work under Linux too, you'll > understand that what I am requesting is a software solution, not a > hardware tinkering guide (although your page is quite impressive, I > admit).

How may I investigate and fix the problem? I think that i2c-pcf-epp is for a Phillips I2C controller chip wired to a parallel port. If the eval board connects SCL/SDA directly to the parallel port, then you want i2c-pport. This may also need some work depending on how SCL/SDA are wired to the parallel cable. Regards, -- Mark M.
