This is on a compaq 5BW120 machine. It uses a Compaq BMW motherboard (MiTAC
6513WU) Intel 82810E Northbridge (GMCH) and 82801 Southbridge (ICH) According
to Compaq support it has 2 ADM1028 sensors (chassis and processor). I have
several of these machines and I have tried this on several different linux
kernel versions 2.4.26, 2.4.28, 2.4.29, and even 2.6.10. The information here
is from 2.4.29 (latest slackware release)

Now follows a summary of the probes I have just done.
Just press ENTER to continue:
Driver `eeprom' (should be inserted):
Detects correctly:
* Bus `SMBus I801 adapter at eee0' (Non-I2C SMBus adapter)
Busdriver `i2c-i801', I2C address 0x50
Chip `SPD EEPROM' (confidence: 8)
* Bus `SMBus I801 adapter at eee0' (Non-I2C SMBus adapter)
Busdriver `i2c-i801', I2C address 0x51
Chip `SPD EEPROM' (confidence: 8)
To make the sensors modules behave correctly, add these lines to
/etc/modules.conf:
#----cut here----
# I2C module options
alias char-major-89 i2c-dev
#----cut here----
To load everything that is needed, add this to some /etc/rc* file:
#----cut here----
# I2C adapter drivers
modprobe i2c-i801
# I2C chip drivers
modprobe eeprom
# sleep 2 # optional
/usr/local/bin/sensors -s # recommended
#----cut here----
