http://www.robot-electronics.co.uk/htm/using_the_i2c_bus.htm "All I2C addresses are either 7 bits or 10 bits. The use of 10 bit addresses is rare and is not covered here. " Maybe we should not worry about it, but there was at one point the possibility of 10 bit addresses. I'm fine either way. thanks ron -- coreboot mailing list coreboot@coreboot.org http://www.coreboot.org/mailman/listinfo/coreboot
