	  Basically any adapter using the parallel port as an I2C bus with

	  This driver is a replacement for (and was inspired by) an older

	  An adapter type parameter is now mandatory.  Please read the file

	  This driver is a light version of i2c-parport.  It doesn't depend

	  might be preferred on embedded systems where wasting memory for
	  the clean but heavy parport handling is not an option.  The
	  drawback is a reduced portability and the impossibility to
	  daisy-chain other parallel port devices.

	  Don't say Y here if you said Y or M to i2c-parport.  Saying M to
