What is it?
-----------
MBProbe is a program which monitors voltages, temperatures and fan speeds
using monitoring chip(s) present on many modern motherboards.
Its features include:
o Up to 8 voltage, 3 temperature and 3 fan speed readings (subject to
the limitations of monitoring chip(s) present).
o Automatic detection of monitoring chips.
o Small memory footprint.
o Setting of nominal voltage and fan speeds with warning thresholds.
o Setting of temperature warning limits and offset readings.
o Setting of sensor used for each temperature reading.
o Temperature display in Celsius or Fahrenheit.
o Customisable task when any temperature exceeds critical limit for
more than 30 seconds continuously.
o Ignores fan warnings for 10 seconds after system comes out of suspend.
o Swappable temperature display in status icon on taskbar.
o Event and history logs.

Usage
-----
Simply start MBProbe from the Windows start menu. The first time it starts,
it attempts to automatically configure the CPU voltage and temperature sensors
settings. All voltage warnings are enabled as well as motherboard temperature
warning. Warnings for CPU and power supply temperature as well as for each fan
will be enabled if the relevant sensors are present.
If there is a problem with accessing the SMBus on your system, start MBProbe
with the "-nosmbus" parameter from the command-line:
MBProbe -nosmbus
The event log is stored in the file "MBProbeEventLog.txt" and it logs warning
events and critical events. The history log is stored in the file
"MBProbeHistoryLog.txt" and it stores spot readings taken at regular
intervals.
Status icon
-----------
The status icon shows the current temperature of the selected device. This
has a range from 0-199 with the display saturating at either end i.e. if the
reading is greater than 199, it will display 199.
Left-click to display the main window or right-click to display the
context menu. The 'reset warning' option is used to clear the horizontal
lines which are displayed after a warning event has occurred.
The tooltip displays motherboard temperature, CPU temperature and CPU fan
speed.
Main window
-----------
The main window shows all the readings obtained from the monitoring chip(s).
The chips are read every 5 seconds.
The check box on the left of each item enables/disables the warning for each
reading. The light on the right shows the status of the reading:
Grey : Warning disabled
Green: OK
Red : Warning threshold exceeded- action needed
The main window automatically pops-up when a warning threshold has been
exceeded.
Properties
----------
The properties dialog consists of 4 tabs:
o General
This displays information about your CPU and monitoring chips. These are
autodetected and cannot be modified. The value for the CPU voltage is
derived from the CPUID (identification instruction sent to the CPU).
o Voltage
This allows you to set the nominal voltage for your CPU core and 3.3V I/O.
The warning threshold setting limits the deviation of all voltage readings
to within that percentage. E.g. a nominal voltage of 2.00V and a 10% warning
threshold triggers a warning when the voltage drops below 1.90V or rises
above 2.10V.
o Temperature
The warning limit sets the temperature which, when exceeded, will trigger a
warning.
The temperature offset is added to the raw temperature reading from the
sensor. This is generally only required for Socket-7 CPUs.
The sensor input allows you to set the temperature sensor corresponding to
each reading. This is to allow for the different sensors adopted by various
motherboard manufacturers. Note that only sensors detected on your system
are displayed.
The CPU thermal diode option is only enabled on certain chips. The
W83782D/3S have temperature inputs which can be connected to either
thermistors or thermal diodes. Check the correct sensor for those connected
to a thermal diode. The ADM1024 has inputs which are either connected to
Vccp2 and +2.5V or to a thermal diode.
o Fan
This allows you to set the nominal fan speed for each fan. Typical values
are 2200, 4400 and 8800RPM. Check your fan manufacturer for the correct
value, otherwise just take the current reading as the nominal value.
The 'warning below' option sets the threshold at which a warning will be
triggered. E.g. a 4400RPM nominal speed and 70% threshold will trigger a
warning when the fan speed drops below 3080RPM. A fan dropping below 70% of
its nominal speed is generally accepted as a 'blocked' fan.
The divisor option is due to the way fan speeds are calculated from the
values given by the monitoring chip. If you have a fan connected to an
input and it shows 0RPM, try selecting a higher fan divisor.
The labels option allows you to specify the labels for each fan input. This
is due to the fact that labelling is non-standard among different
motherboard manufacturers.
If you have a FanTemp connected to one of the fan inputs, click Calibrate
to adjust the software calibration.
o Tasks
A warning event can trigger one or more actions: bringing the main window
to the top, beeping the speaker, blinking the status icon and logging
the warning in the event log.
A critical event occurs when any temperature exceeds the value specified
above the warning limit for greater than 30 seconds continuously. The system
can then be suspended or shutdown.
For either event, you can choose to execute a program. Enter the complete
pathname to the executable or browse by clicking '...'.
The history log can be optionally enabled here. You can also set the time
interval as steps of 5 seconds.
o Display
The temperature(s) displayed in the status icon can be specified here. If
more than one temperature input is selected, they will be swapped at the
speified interval.
The temperature units can be specified as either in Celsius or Fahrenheit.
The temperature/fan readings in the tooltip can be specified by checking
the appropriate box.
Known issues
------------
o Minor cosmetic issues
- Changing some settings does not affect the reading/display immediately.
- Changing the temperature units does not affect the units in the
temperature property sheet immediately.
- Changing the temperature units does not affect the headers in the history
log. Clear the history log to update the header.
- The frequency of swapping the temperature display in the system tray is
not exact. This is due to the inaccuracy of the standard timer event.
- Viewing a log multiple times will result in multiple copies of Notepad.
- If you uncheck all status icon temperatures and click OK, MBProbe will
automatically enable the motherboard temperature display. This is to
ensure that a temperature will be displayed in the status icon.
- Checking too many temperature/fan readings for the tooltip may result in
the tooltip being truncated. This is a limitation of Windows and no
workaround is available.
o NT issues
- Suspending the system does not work under NT 4.0 because the OS does not
support power management; upgrade to Windows 2000.
- Shutting down the system requires the shutdown privilege under NT/W2000.
MBProbe attempts to request for this privilege but may not be successful.
o Hardware issues
- ADM1020 chips will be identified as an ADM1021 as it is compatible.
There appears to be no way to distinguish between the 2 in software.
- Systems with a VIA Apollo Pro chipset (VT82C691A+VT82C596A) may
lock-up when starting MBProbe. If this happens start MBProbe with the
"-nosmbus" parameter. If monitoring chips in your system are connected to
the SMBus only, then nothing will be detected. Please ask the vendor for
a BIOS upgrade to fix this problem.
o Untested hardware (programming based on the data sheets):
. ALi M1535
. ADM1022, ADM1024, ADM1025
. FMS2701
. THMC50
Feedback is needed. Please report your success/failures, a complete set of
readings, motherboard, chip address. Thanks.
. ADM1022/4/5, FMS2701: Preliminary datasheets, specs may change.
Unsupported
-----------
o The following monitoring chips are currently unsupported:
. National Semiconductor LM76, LM77
If you have one of these and would like to help out, contact me and I'll
give you some test programs to run.
o The following SMBus host chipsets are currently unsupported:
. SiS 5595B
o I2C host chipsets are unsupported. Some examples are:
. SiS 5595 (hardware monitoring portion is supported though)
. VIA VT82C586B
These chipsets only contain an I2C host and depend on the software to
simulate the SMBus protocol. This is messy and time consuming to implement
and the fact that I don't have the hardware to test it on means support
will not be implemented.
If anyone has written code for this and would be willing to allow inclusion
of it in MBProbe then please contact me.
