I am trying to develop the ability to read the temperature sensors on my motherboard with perl. I have been doing a lot of Googling and have learned quite a bit. But, I seem to be running out of time faster than I am running out of things to learn. Thus, I'm hoping someone out there has done something similar and can give me a little help.
Here are a few details of where I am at:
OS: The system has Win-XP on it. Thus, it would be nice to be able to use something like ActivePerl (www.activestate.com) and XP. I would prefer to use Linux, but it is an XP box so this has to be on my wish list. There will be times when I must be running XP and a live-CD will not always be an option.
LINUX can be run at times from a live CD. Damn Small Linux (www.damnsmalllinux.org) with its MyDSL system for adding packages looks very handy. The Damn Small Linux - Not (www.damnsmalllinux.org/dsl-n/) big brother looks even better.
MOTHERBOARD: Ampro LittleBoard 800 with a Pentium M processor.
The motherboard has an Intel 82810DB I/O controller hub "Northbridge" on the System Management Bus (SMBus) at $D800 as reported by SpeedFan.
The motherboard has an Analog Devices ADM1021 temperature chip on the SMBus at $4E as reported by SpeedFan.
The SpeedFan 4.29 package (www.almico.com/speedfan.php) found two temperature sensors on the motherboard and one in the hard drive. The motherboard sensors are accessed via the SMBus (www.smbus.org/specs/) and the hard drive sensor is accesses via the Self Monitoring Analysis and Reporting Technology System (SMART).
Included is a dump of the information available through SpeedFan. Most of it makes sense but I don't know how to get to it from perl. I don't know what is being referred to with the "sensors base address = $0C00" statement. This address doesn't match the SMBus or other sensor address given.
There are probably sensors or LMsensors packages available that will be helpful on the Linux operating system. I doubt that there is a similar resource available under Win-XP.

Bottom line ... I would like to read the two SMBus motherboard temperature sensors and the one SMART hard drive temperature sensor from perl. Linux is my preferred OS (live-CD would be used), XP is the OS that must be permanently on the box. Any ideas or suggestions would be appreciated.
Thank you,
Bruce
