72Forcing the address
73-------------------
74
75The driver used to have a module parameter named force_addr, which could
76be used to force the base I/O address of the hardware monitoring block.
77This was meant as a workaround for mainboards with a broken BIOS. This
78module parameter is gone for technical reasons. If you need this feature,
79you can obtain the same result by using the isaset tool (part of
80lm-sensors) before loading the driver:
81
82# Enter the Super I/O config space
83isaset -y -f 0x2e 0x87
84isaset -y -f 0x2e 0x87
85
86# Select the hwmon logical device
87isaset -y 0x2e 0x2f 0x07 0x0b
88
89# Set the base I/O address (to 0x290 in this example)
90isaset -y 0x2e 0x2f 0x60 0x02
91isaset -y 0x2e 0x2f 0x61 0x90
92
93# Exit the Super-I/O config space
94isaset -y -f 0x2e 0xaa
95
96The above sequence assumes a Super-I/O config space at 0x2e/0x2f, but
970x4e/0x4f is also possible.
