+Building & Installing
+---------------------
+
+* make clean
+* make
+* sudo make install
Module Parameters
misconfigured by BIOS - PWM values would be inverted. This option tries
to fix this. Please contact your BIOS manufacturer and ask him for fix.
+* force_id
+
+ Force chip ID to specified value. Should only be used for testing.
+
+* ignore_resource_conflict
+
+ Similar to acpi_enforce_resources=lax, but only affects this driver.
+ ACPI resource conflicts are ignored if this parameter is provided and
+ set to 1.
+ Provided since there are reports that system-wide acpi_enfore_resources=lax
+ can result in boot failures on some systems.
+ Note: This is inherently risky since it means that both ACPI and this driver
+ may access the chip at the same time. This can result in race conditions and,
+ worst case, result in unexpected system reboots.
+
+* mmio
+
+ If set to 1, the driver uses MMIO to access the chip if supported. This is
+ faster and less risky (untested!).

+This driver implements support for the IT8603E, IT8620E, IT8622E, IT8623E,
+IT8628E, IT8705F, IT8712F, IT8716F, IT8718F, IT8720F, IT8721F, IT8726F, IT8728F,

These chips are 'Super I/O chips', supporting floppy disks, infrared ports,
joysticks and other miscellaneous stuff. For hardware monitoring, they
If a temperature sensor is configured for thermistors, the attribute values
are ignored. If the thermal sensor type is Intel PECI, the temperature offset
must be programmed to the critical CPU temperature.

+Preliminary support
+-------------------
+
+Support for IT8607E is preliminary. Voltage readings, temperature readings,
+fan control, and fan speed measurements may be wrong and/or missing.
+Fan control and fan speed may be enabled and reported for non-existing
+fans. Please report any problems and inconsistencies.
+
+Reporting information for unsupported chips
+-------------------------------------------
+
+If the chip in your system is not yet supported by the driver, please provide
+the following information.
+
+First, run sensors-detect. It will tell you something like
+
+ Probing for Super-I/O at 0x2e/0x2f
+ ...
+ Trying family `ITE'... Yes
+ Found unknown chip with ID 0x8665
+ (logical device 4 has address 0x290, could be sensors)
+
+With this information, run the following commands.
+
+sudo isadump -k 0x87,0x01,0x55,0x55 0x2e 0x2f 7
+sudo isadump 0x295 0x296
+
+and report the results.
+
+The addresses in the first command are from "Probing for Super-I/O at
+0x2e/0x2f". Use those addresses in the first command.
+ sudo isadump -k 0x87,0x01,0x55,0x55 0x2e 0x2f 7
+
+The addresses in the second command are from "has address 0x290".
+Add 5 and 6 to this address for the next command.
+ sudo isadump 0x295 0x296
+
+Next, force-install the driver by providing one of the already supported chips
+as forced ID. Useful IDs to test are 0x8622, 0x8628, 0x8728, and 0x8732, though
+feel free to test more IDs. For each ID, instantiate the driver as follows
+(this example is instantiating driver with ID 0x8622).
+ sudo modprobe it87 force_id=0x8622
+After entering this command, run the "sensors" command and provide the output.
+Then unload the driver with
+ sudo modprobe -r it87
+Repeat with different chip IDs, and report each result.
+
+Please also report your board type as well as voltages and fan settings from
+the BIOS. If possible, connect fans to different fan headers and let us know
+if all fans are detected and reported.
+
+This information _might_ give us enough information to add experimental support
+for the chip in question. No guarantees, though - unless a datasheet is
+available, something is likely to be wrong.
+
+A note on sensors-detect
+========================
+
+There is a persistent perception that changes in this driver would have impact
+on the output of sensors-detect. This is not the case. sensors-detect is an
+independent application. Changes in this driver do not affect sensors-detect,
+and changes in sensors-detect do not affect this driver.
