+Kernel driver abituguru3
+========================
+
+Supported chips:
+ * Abit uGuru revision 3 (Hardware Monitor part, reading only)
+ Prefix: 'abituguru3'
+ Addresses scanned: ISA 0x0E0
+ Datasheet: Not available, this driver is based on reverse engineering.
+ Note:
+ The uGuru is a microcontroller with onboard firmware which programs
+ it to behave as a hwmon IC. There are many different revisions of the
+ firmware and thus effectivly many different revisions of the uGuru.
+ Below is an incomplete list with which revisions are used for which
+ Motherboards:
+ uGuru 1.00 ~ 1.24 (AI7, KV8-MAX3, AN7)
+ uGuru 2.0.0.0 ~ 2.0.4.2 (KV8-PRO)
+ uGuru 2.1.0.0 ~ 2.1.2.8 (AS8, AV8, AA8, AG8, AA8XE, AX8)
+ uGuru 2.3.0.0 ~ 2.3.0.9 (AN8)
+ uGuru 3.0.0.0 ~ 3.0.x.x (AW8, AL8, AT8, NI8 SLI, AT8 32X, AN8 32X,
+ AW9D-MAX)
+ The abituguru3 driver is only for revison 3.0.x.x motherboards,
+ this driver will not work on older motherboards. For older
+ motherboards use the abituguru (without the 3 !) driver.

+
+Module Parameters
+-----------------
+
+* force: bool Force detection. Note this parameter only causes the
+ detection to be skipped, and thus the insmod to
+ succeed. If the uGuru can't be read the actual hwmon
+ driver will not load and thus no hwmon device will get
+ registered.
+* verbose: bool Should the driver be verbose?
+ 0/off/false normal output
+ 1/on/true + verbose error reporting (default)
+ Default: 1 (the driver is still in the testing phase)
+
+Description
+-----------
+
+This driver supports the hardware monitoring features of the third revision of
+the Abit uGuru chip, found on recent Abit uGuru featuring motherboards.
+
+The 3rd revision of the uGuru chip in reality is a Winbond W83L951G.
+Unfortunatly this doesn't help since the W83L951G is a generic microcontroller
+with a custom Abit application running on it.
+
+Despite Abit not releasing any information regarding the uGuru revision 3,
+Louis Kruger has managed to reverse engineer the sensor part of the uGuru.
+Without his work this driver would not have been possible.
+
+Known Issues
+------------
+
+The voltage and frequency control parts of the Abit uGuru are not supported,
+neither is writing any of the sensor settings and writing / reading the
+fanspeed control registers (FanEQ)
+
+If you encounter any problems please mail me <j.w.r.degoede@hhs.nl> and
+include the output of: "dmesg | grep abituguru"
