Hello Alex and Mark, I'm referring to your discussions at http://archives.andrew.net.au/lm-sensors/msg01299.html I have got a new notebook "Mitac 8640m". (The same as in http://archives.andrew.net.au/lm-sensors/msg03881.html ) It is based on a SiS645DX ("SiS646") northbridge and a SiS962 southbridge. There is a SMBus device 1039:0016 from SiS, but the BIOS (which does not seem very usable) seems to hide that device. (See http://archives.andrew.net.au/lm-sensors/msg01872.html ). * When using Linux 2.6, the device is unhidden at boot ( http://archives.andrew.net.au/lm-sensors/msg02573.html ). * Under Linux 2.4, i2c-sis645 seems to unhide it (but not for the kernel, "lspci" won't show it, but "lspci -H1" will show it). * Under Windows, MBM seems to unhide it. Unfortunately, the I/O-ports will not be enabled, * neither under Windows using MBM 5.3.5.0 * nor under Linux 2.6 using i2c-sis96x (Linux 2.6.0) * nor under Linux 2.4 using i2c-sis645 (lm-sensors 2.8.2). I can verify this by looking at the PCI config space word at byte offset 0x04 ("PCI_COMMAND", see http://lxr.linux.no/source/include/linux/pci.h?v=2.6.0#L28 ). For I/O ports being enabled bit 0 (PCI_COMMAND_IO) has to be set. This is not the case: <MBM PCI Dump> Bus :00 Device :02 Func :01 Vendor :1039 Device ID :0016 $0000: 39 10 16 00 00 00 80 02 00 00 05 0C 00 00 00 00 </MBM PCI Dump> Under Linux 2.4 and Linux 2.6, I can try to manually set PCI_COMMAND=0x01. This works, so that then modules "i2c-sis96x" and "i2c-sis645" respectively can be loaded. * But under Linux 2.6, "i2cdetect 0" returns only "XX" results and is pretty slow. I enabled the "#define DEBUG" in the sourcecode if "i2c-sis96x" and saw that every request to the SMBus times out. * Under Linux 2.4, "i2cdetect 0" or "sensors" crashes with a (recoverable) kernel oops Under Windows, the pci device actually cannot be enabled manually (after running MBM 5, device manager will recognize an "SM-Bus-Controller", but I cannot find a driver for that device). When running "SMB Dump" in MBM, I get this: ------MBM SMB DUMP------- SMB SiS0016 via SiS0008 @ $0000 SMBus Register :$10 $0000: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 $0010: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 $0020: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 [...only zeros...] So it seems that I'm missing something when manually enabling the device. MBM 5.3.5.0 also seems to misidentify the device (SiS5595 instead of SiS962) and base I/O port address (the I/O-port-space of the SMBus device is at 0x1080). So I'm asking you (Alex and Mark) wether it is possible to enable the device not just by unhiding it, but also by enabling I/O-ports and other stuff I'm not familiar with so that the SMBus device will get usable. I'd like to get rid of the CPU fan noise by manually controlling the CPU fan based on CPU temperature (or by even unplugging the CPU fan and verifying success by reading the CPU temperature). I'm willing to run tests, alpha versions and the like. Thank you, Xu?n. ----MBM SYSTEM INFO----- MBM 5.3.5.0 MBM 5 Core EXE : 5.3.5.0 MBM 5 Core DLL : 5.3.5.1 MBM 5 Settings DLL : 5.3.5.0 MBM 5 Dashboard DLL : 5.3.5.0 MBM 5 Hibernation DLL : 5.0.0.0 MBM 5 Ras DLL : 5.0.0.0 MBM 5 Logger DLL : 5.3.4.0 MBM 5 Mail, FTP and UDP DLL : 5.3.4.0 MBM 5 OSD DLL : 5.0.0.3 MBM 5 ASPI DLL : 5.2.1.0 MBM 5 Heat Up EXE : 5.0.0.0 MBM 5 Wizard : 5.3.5.0 MBMIO DLL : 1.0.0.2 MBMIO Driver : 1.1 DLL Folder Location : C:\Programme\Motherboard Monitor 5\DLL\ Data Folder Location : C:\Programme\Motherboard Monitor 5\Data\ Language Folder Location : C:\Programme\Motherboard Monitor 5\Language\ Log Folder Location (Alarm) : c:\programme\motherboard monitor 5\log\ Log Folder Location (High Low): c:\programme\motherboard monitor 5\log\ Log Folder Location (Interval): c:\programme\motherboard monitor 5\log\ Selected Language : English Info ChipInfo.ini : 16576 bytes 24.10.2003 13:37:26 Info shdn.ini : 388 bytes 12.10.2000 18:47:06 Info Voltage.ini : 31808 bytes 24.10.2003 13:09:22 Info Language file : 22920 bytes 17.10.2003 08:33:40 Up Time MBM session : 00:00:11:23 Up Time MBM total : 00:00:32:02 ------Sensor Chip------- Main Sensor Chip : Sis SiS5595 SMB Address : $0000 Used Bus : ISA ISA Address : $8008 -Sensor Chip Selections- Possible Temp Sensors[2] : SiS5595 Selected Temp Sensors[1] : SiS5595 (115) Selected Temp Sensors[2] : Custom (185) Selected Temp Sensors[3] : Custom (185) Possible Voltage Sensors[2] : MBM Fixed Selected Voltage Sensors[1] : MBM Fixed (2) Selected Voltage Sensors[2] : MBM Fixed (2) Selected Voltage Sensors[3] : MBM Fixed (2) Selected Voltage Sensors[4] : MBM Fixed (2) Selected Voltage Sensors[5] : MBM Fixed (2) Selected Voltage Sensors[6] : MBM Fixed (2) Selected Voltage Sensors[7] : MBM Fixed (2) Possible Fan Sensors[1] : SiS5595-1 Possible Fan Sensors[2] : SiS5595-2 Selected Fan Sensors[1] : SiS5595-1 T1 D4 (32) Selected Fan Sensors[2] : SiS5595-2 T1 D4 (33) Selected Fan Sensors[3] : Asus-3 T1 D4 (31) Possible Voltage Sub Types[0] : Sis 5595 Standard Selected Voltage Sub Type : Sis 5595 Standard (0) --Sensor Chip Readings-- Temperature Readout[1] : 51 Temperature Readout[2] : 51 Voltage Readout[1] : 4,08 Voltage Readout[3] : 4,08 Voltage Readout[4] : 6,8544 Voltage Readout[5] : 15,504 ---------System--------- Operating System : Microsoft Windows XP (NT 5.1) (Build 2600) Service Pack 1 User : Administrator Memory in use : 89% Total Physical Memory : 261616 KB Available Physical Memory : 28716 KB ----------CPU----------- CPU Speed : 1792 MHz Nr of CPU's : 1 -------3rd Party-------- ShutDownNow : ----Advanced Settings--- Fan Temp : 0 Custom Temp Table : 0 Startup Delay : 0 2E 4E Enabled : 0 2E Forced : 0 4E Forced : 0 Do Not Reset : 1 SMB Scan Range : $10 - $7F
