Hi,

I'm interested in getting infos about the heat into my computer (a Compaq
Presario Serie 1200) so i read 'LINT', and various man such as viapm, smb,
smbus etc.
Finally i get a kernel config file with:

device          smbus
device          smb
device          viapm

device          iicbb
device          iicbus

and in dmesg:
viapropm0: <VIA VT82C686A Power Management Unit> port 0x8080-0x808f at device 7.4 on pci0
smb0: <SMBus general purpose I/O> on smbus0

According to me, everything seems OK, but lmmon and healthd give me some strange answers...

First when using /dev/smb0, they tell me:
'IOCTL: Invalid argument'

or when using the /dev/io they give me wrong values (like 255°C into the computer.. :>)

So, my questions are:
- does my motherboard support sensors (temperature for example) ?
- did i make something wrong ?

here is a 'dmesg | grep VIA':

isab0: <VIA 82C686 PCI-ISA bridge> at device 7.0 on pci0
atapci0: <VIA 82C686 ATA66 controller> port 0x1420-0x142f at device 7.1 on pci0
pci0: <VIA 83C572 USB controller> at 7.2 irq 11
viapropm0: <VIA VT82C686A Power Management Unit> port 0x8080-0x808f at device 7.4 on pci0
pcm0: <VIA VT82C686A> port 0x1430-0x1433,0x1434-0x1437,0x1000-0x10ff irq 9 at device 7.5 on pci0

Thanks in advance.
