MBProbe

Known Issues

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.

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.
• A few people have reported trouble installing or uninstalling the giveio.sys driver. Unfortunately I have not been able to reproduce this under Win2000 or XP. As such, I am unable fix it.
• A few people have reported problems running full-screen DOS applications and/or accessing the floppy drive with the giveio.sys driver installed. Unfortunately I have not been able to reproduce this under Win2000 or XP. As such, I am unable to fix it.

Hardware issues

• 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.
• Untested hardware (programming based on the data sheets):

• ADM1022
• GL525SM
• LM83
• MTP008
• FMS2701
• THMC50

Feedback is needed. Please report your success/failures, a complete set of readings, motherboard, chip address. Thanks.

• ADM1022/4, FMS2701: Preliminary datasheets, specs may change.

Unsupported hardware

• The following monitoring chips are currently unsupported:

• National Semiconductor LM76, LM77, LM82, LM92

If you have one of these and would like to help out, contact me and I'll give you some test programs to run.

• The following SMBus hosts are currently unsupported:

• SiS 5595B, 540, 630

It is probably not necessary to support these as they already have built-in hardware monitoring.

• I2C hosts are unsupported. Some examples are:

• SiS 5595 (hardware monitoring portion is supported though)
• VIA VT82C586B (common in MVP3 chipsets)

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.
