My original m/b has ITE8712 so i had set modprobe i2c-isa it87. When
i switched to the new Gigabyte m/b this did not work because there was no
/sys/devices/platform/i2c-9191/9191-0290/ created.

Do you want to scan the ISA bus? (YES/no):

Do you want to scan for Super I/O sensors? (YES/no):

 Sorry, no chips were detected.
