Hello,
http://www.almico.com/sfdownload.php
I downloaded the exe speedfan and executed it. This exe gave me the fan
details. I don’t know if it is using any device driver to read the fan and
temperature details of a custom motherboard.
I got the log file generated from speedfan that gave the details of the chip
that stores the fan and temperature details.
Here is the log:
A)
When ran SpeedFan Application in My Desktop
Linked ISA BUS at $0290
Linked Intel 82801DB ICH4 SMBUS at $5000
SuperIO Chip=IT8712F
Scanning Intel SMBus at $5000…
SMART Enabled for drive 0
Found ST340015A (40.0GB)
End of detection
CLOCK GENERATOR set to ICS 9248-90
B)
When We ran SpeedFan Application in Actual Environment
Linked ISA Bus at $0290
Linked Intel 82801FB ICH6 SMBus at $0290
Winbond W83627HF (ID=$21) found on ISA at $290
SuperIO chip = Winbond W83627HF (This is the chip that I am interested in)
Also, I tried to find if it is already using any standard windows device
driver by running the dumpbin.exe.
I need to do the same thing as SpeedFan exe is doing. Please advice.
Regards,
Sivakumar Jayapal

You are correct, that’s why I wrote a simple driver .

Nope you need a driver to do the mapping, if you do the mapping you open
a
security hole in the OS and the code to do the mapping is more complex
than
the driver that does it correctly!

Can it be done through without a driver?? May be mapping the physical
memory to virtual address space with NtmapViewOfSection API? Is this is
an authentic way or not?
Thanks and Regards

You need a device driver. Probably a pretty simple one, that just gets
the
data in an IOCTL or two.

Hello
I have a problem that I need help from the list.
The device is a custom motherboard with Intel processor that contains a
chip, which controls various operations of the device such as fans,
temperature sensors.
The onboard chip is a memory mapped. There are no BIOS. Hence, I need
to
read the fan and temperature sensor data using the physical memory
address
that is available with me. Now, I have to communicate with this device
from
my Windows XP application using virtual device framework. I am not sure
how
to achieve this.
I have the physical memory location of the device and the offsets to
read
data of fans and temperature sensors.
My requirement is to just read that location and fetch the data, how do
I
achieve this. Please advice.
Regards,
Sivakumar Jayapal
