Jean,
Do you use any instant message programs? I have Yahoo Messenger, MSN
Messenger, and AIM, and it might be easier to communicate instead of
waiting for e-mails.

Well, I can look at the motherboard and actually see the Winbond chip
right there on the board. It has the winbond logo and the number on it
is W83627EHF-A.

I didn't notice the "-A" before, but I'm not sure if that means
anything.

I have gone into my BIOS settings and looked at the hardware monitor
and here are some of the settings it monitors:
--------------
CPU Temp
MB Temp
CPU Q-Fan Control
CPU Q-Fan Mode
CPU Fan Ratio
CPU Target Temperature
CPU Fan Speed
Chassis Fan Speed
Vcore Voltage
3.3V Voltage
5V Voltage
12V Voltage
--------------

The Q-fan thing is specific to Asus and can automatically turn fan
speeds up and down depending on temperatures.

Here is the output from "isadump 0x295 0x296":
WARNING! Running this program can cause system crashes, data loss and
worse!
I will probe address register 0x295 and data register 0x296.
