Hello
I'm trying to get temperature info about CPUs on Dell Precision 670
motherboard.
I have kernel (FreeBSD 6.1-STABLE #0: Fri Jun 30 07:12:09 CEST 2006)
with SMB
device smb
device smbus
device intpm
device ichsmb
device iicbus # Bus support, required for
ic/iic/iicsmb below.
device iicbb
device ic
device iic
device iicsmb # smb over i2c bridge
the SMB device is
tnt-new:~# dmesg | grep smb
ichsmb0: <Intel 82801EB (ICH5) SMBus controller> port 0xece0-0xecff irq
17 at device 31.3 on pci0
ichsmb0: [GIANT-LOCKED]
smbus0: <System Management Bus> on ichsmb0
smb0: <SMBus generic I/O> on smbus0
ichsmb0@pci0:31:3: class=0x0c0500 card=0x01681028 chip=0x24d38086
rev=0x02 hdr=0x00
vendor = 'Intel Corporation'
device = '82801EB/ER (ICH5/ICH5R) SMBus Controller'
class = serial bus
subclass = SMBus
but if I run mbmon (with SMB support, compiled from ports) I got this
error at the end
tnt-new:~# mbmon
ioctl(smb0:writebyte): Device not configured
Exit 255
tnt-new:~# mbmon -D
