using hardware sensors on MB 741LMRT

Post by Frederi » Thu, 07 Sep 2000 07:21:24

I'm experiencing some problems getting my hardware sensors to work (using
lm-sensors). I have a PCChips motherboard, model MB-741LMRT. This uses a
SiS 5595 b2/b3 chip.
This is the result of 'sensors':
Adapter: ISA adapter
Algorithm: ISA algorithm
VCore 1:   +2.04 V  (min =  +2.84 V, max =  +3.45 V)   ALARM
VCore 2:   +1.98 V  (min =  +2.68 V, max =  +3.26 V)   ALARM
+3.3V:     +1.23 V  (min =  +2.97 V, max =  +3.63 V)   ALARM
+5V:       +0.91 V  (min =  +3.78 V, max =  +4.62 V)   ALARM
fan1:        0 RPM  (min = 3000 RPM, div = 2)          ALARM
fan2:        0 RPM  (min = 3000 RPM, div = 2)          ALARM
temp:     +127 C     (limit = +60 C,  hysteresis = +50 C) ALARM
alarms:   Board temperature input (usually LM75 chips) ALARM

Of course, the cpu is not really 127 , this is however the value that is
always showing up. Through the BIOS, correct temperatures can be seen at

Anyone experience with this kind of MB/chip?




1. Metolious hardware-sensors-using-ACPI specs

Wow, is that still on a website somewhere?

So as you may know from looking at the spec, Metolious was a spec that
defined a way for platforms to enumerate various motherboard sensors to the
OS, for manageability purposes.

It never took off, except for a couple companies that used the Windows
driver for other things because they didn't want to write a driver that
received ACPI device Notify()s.

The licensing may be weird, but given that there really is no point in
implementing it on Linux, does that really matter?
