6 Prefix: 'abituguru3'
7 Addresses scanned: ISA 0x0E0
8 Datasheet: Not available, this driver is based on reverse engineering.
9 Note:
10 The uGuru is a microcontroller with onboard firmware which programs
11 it to behave as a hwmon IC. There are many different revisions of the
12 firmware and thus effectivly many different revisions of the uGuru.
13 Below is an incomplete list with which revisions are used for which
14 Motherboards:
15 uGuru 1.00 ~ 1.24 (AI7, KV8-MAX3, AN7)
16 uGuru 2.0.0.0 ~ 2.0.4.2 (KV8-PRO)
17 uGuru 2.1.0.0 ~ 2.1.2.8 (AS8, AV8, AA8, AG8, AA8XE, AX8)
18 uGuru 2.3.0.0 ~ 2.3.0.9 (AN8)
19 uGuru 3.0.0.0 ~ 3.0.x.x (AW8, AL8, AT8, NI8 SLI, AT8 32X, AN8 32X,
20 AW9D-MAX)
21 The abituguru3 driver is only for revison 3.0.x.x motherboards,
22 this driver will not work on older motherboards. For older
23 motherboards use the abituguru (without the 3 !) driver.

34 detection to be skipped, and thus the insmod to
35 succeed. If the uGuru can't be read the actual hwmon

43Description
44-----------
45
46This driver supports the hardware monitoring features of the third revision of
47the Abit uGuru chip, found on recent Abit uGuru featuring motherboards.
48
49The 3rd revision of the uGuru chip in reality is a Winbond W83L951G.
50Unfortunatly this doesn't help since the W83L951G is a generic microcontroller
51with a custom Abit application running on it.
52
53Despite Abit not releasing any information regarding the uGuru revision 3,
54Louis Kruger has managed to reverse engineer the sensor part of the uGuru.
55Without his work this driver would not have been possible.
56
57Known Issues
58------------
59
60The voltage and frequency control parts of the Abit uGuru are not supported,
61neither is writing any of the sensor settings and writing / reading the
