72 | Forcing the address | ||
73 | ------------------- | ||
74 | |||
75 | The driver used to have a module parameter named force_addr, which could | ||
76 | be used to force the base I/O address of the hardware monitoring block. | ||
77 | This was meant as a workaround for mainboards with a broken BIOS. This | ||
78 | module parameter is gone for technical reasons. If you need this feature, | ||
79 | you can obtain the same result by using the isaset tool (part of | ||
80 | lm-sensors) before loading the driver: | ||
81 | |||
82 | # Enter the Super I/O config space | ||
83 | isaset -y -f 0x2e 0x87 | ||
84 | isaset -y -f 0x2e 0x87 | ||
85 | |||
86 | # Select the hwmon logical device | ||
87 | isaset -y 0x2e 0x2f 0x07 0x0b | ||
88 | |||
89 | # Set the base I/O address (to 0x290 in this example) | ||
90 | isaset -y 0x2e 0x2f 0x60 0x02 | ||
91 | isaset -y 0x2e 0x2f 0x61 0x90 | ||
92 | |||
93 | # Exit the Super-I/O config space | ||
94 | isaset -y -f 0x2e 0xaa | ||
95 | |||
96 | The above sequence assumes a Super-I/O config space at 0x2e/0x2f, but | ||
97 | 0x4e/0x4f is also possible. | ||
