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)
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.

Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
