It may give you access to I2C/SMBus hardware monitoring chips, but isn't itself a hardware monitoring chip. > (Note: for kicks I also went into the lm_sensors source and 'hacked' the > SERVERWORKS CSB6 0x0203 PCI-id to be 0x0205 both the sensors-detect script > and in the i2c_piix4 code contained there. It didn't help.) The i2c-piix4 driver found in the lm_sensors is a Linux 2.4 driver, so it is of no use to you. Adding the ID to sensors-detect will let it autoload the i2c-piix4 driver, but given that you had manually loaded it beforehand anyway, it did not change anything for you. Please check your logs after loading the i2c-piix4 driver. Did it complain of anything? Second, please provide the full output of sensors-detect. There are many possible reasons why no chips were found on your HT-1000, and this output should help us sort through them. You may also provide the output of "i2cdetect 0" (assuming that the HT-1000 is the only i2c adapter on the system; if not try "i2cdetect -l" first.) > One other possibility is that because I have a BMC card plugged in to the > motherboard (SuperMicro H8SSL-i) the BMC card is not allowing access to > the devices from lm_sensors. BMC are handled by a different set of drivers which were not yet merged into Linux 2.6. See http://bmcsensors-26.sourceforge.net/ if you think this is what you need. I can not help much on this myself. -- Jean Delvare
