- Motherboards
- ------------
- Most motherboards will work on the default MBProbe settings for voltage and
- temperature sensors. The following lists some exceptions:
- (Look for the sensor detected, then look for your board under that section)
- If your board is not listed, try one of the combination of settings listed
- under the appropriate sensor and please mail me about it. Thanks.

- Motherboard Types
- -----------------
- Beginning with 1.30 there is an option to specify the motherboard type. This
- will only be used for motherboards with certain non-standard features (or
- bugs) which cannot be autodetected (or where autodetection may lock-up other
- motherboards).
-
- The following motherboards may be specified:
- 1=Reserved
- 2=FIC SD-11
- Newer BIOSes disabled the hardware monitoring of the VT82C686A. This
- option re-enables it.
- 3=Super I/O at 2eh
- This enables the scanning for the SMSC 47xxxx chips which provide fan
- speed readings. Boards include Intel D815EEA, VC820, OR840 and possibly
- other i8x0-based Intel boards as well.
- This also scans for the NS PC87366 which includes hardware monitoring.
- Boards include Chaintech 6WIM.
- 4=Super I/O at 4eh
- This enables the scanning for the SMSC 47xxxx chips which provide fan
- speed readings and the NS PC87366 which includes hardware monitoring.
-
- If you have any of these motherboards, enable support for it by changing the
- following registry key:
-
- HKEY_LOCAL_MACHINE\Software\Jonathan Teh\MBProbe\1.30\MotherboardType=n
-
- where n is the number of the motherboard given above.
-
- 1. Run regedit.exe
- 2. Go to "HKEY_LOCAL_MACHINE\Software\Jonathan Teh\MBProbe\1.30"
- 3. Select "Edit" from the menu, then "New", then "DWORD Value".
- 4. Type "MotherboardType" (without the quotes).
- 5. Double-click on "MotherboardType" and enter the motherboard type.
- 6. Close regedit.
- 7. Restart MBProbe.
-
- This may become part of the GUI front-end in future versions.
-
- CPU temperature offset
- ----------------------
- Use the following as a guide only (figures in Celsius):
-
- AMD 5k86 PR133 : + 8
- AMD 5k86 PR166 : +17
- AMD K6 166-200 : + 7
- AMD K6 233-300 : +20
- AMD K6-2 450 : + 6 (PC-Chips M598LMR)
- AMD K6-2 500 : +41 (PC-Chips M599)
- AMD K6-2+ 450 : - 4 (PC-Chips M598LMR)
- Cyrix MII PR200 : +15
- IDT WinChip C6 : +20
- Intel Pentium : +32
- Intel Pentium MMX : +22
-
- If your CPU is not listed, check the temperature in the BIOS and compare it
- with the temperature reported by MBProbe. Take the difference as the offset
- and submit a report to me. Thanks.

- Notes
- 1 External temperature measurement requires thermistors or diodes.
- 2 External temperature measurement requires thermistors.
- 3 External temperature measurement requires diodes.
- 4 Voltage input for Vccp2 can also function as -12V.
- 5 Vccp2 reading is actually the sensor chip's Vcc.
- 6 When temperature input 3 is enabled, Vccp2 and +2.5V are disabled
- as they are the same pins.
- 7 At least one board (Tekram P6B40-A4X) uses Vccp2 to connect an external
- thermistor so MBProbe has a custom sensor setting for that.
- 8 These chips can monitor 2 voltages for brownouts but there is no way of
- reading the actual voltage values.
- 9 MBProbe only displays 9 of the 11 voltages; Vdd and AVdd are omitted.

- Temperature-only monitoring chips
