Hi Fiery, It's me again.
I have another Jetway's main board H/W sensor issue which model name: J2NC94. This board cannot be identified by the everest. The sensor type is fintek F71869. I upload the log data for you.
Thanks for your help.

Thank you for the dumps. I'm afraid we're gonna need more, and this time, made by the latest beta.

1) So first of all, please upgrade to the following new beta of EVEREST Ultimate Edition:

http://www.lavalys.c...zyaw7kln5qx.zip

2) After upgrading to this new version, make sure to restart Windows to finalize the upgrade.

3) Start the new version, right-click on the bottom status bar of EVEREST main window --> CPU Debug --> CPUID & MSR Dump

4) Then right-click on the bottom status bar of EVEREST main window --> Sensor Debug --> ISA Sensor Dump.

5) Finally, right-click on the bottom status bar of EVEREST main window --> Sensor Debug --> SMBus Dump (Full).

Thank you for your time.


Regards,
Fiery

Thank you for the dumps. Please upgrade to the latest beta version of EVEREST Ultimate Edition available at:

http://www.lavalys.c...yl2sdx8wgbm.zip

After upgrading to this new version, make sure to restart Windows to finalize the upgrade.

Let me know how it works. Please note that we couldn't figure out all voltage readings, so you won't have them all displayed on the Sensor page in EVEREST. In the case you know someone at Jetway (the manufacturer of the motherboard) who could give you the layout of the sensor registers used on this motherboard, let us know, and we'll further improve the sensor information.


Thanks,
Fiery

Fiery,
EVEREST still can't dentify F71869 by chip id. F71869 is the same as FINTEK SIO F71862.
For more information,do you need the datasheet of F71869 to get sensor registers?

[Fiery]

We've fixed F71869 recognition. Please upgrade to the following new EVEREST beta:

http://www.lavalys.c...fs6dlk1ngwx.zip

After upgrading to this new version, make sure to restart Windows to finalize the upgrade.

Let me know if it helps.


Thanks,
Fiery

Fiery,
EVEREST can dentify F71869 using the new version. Other voltage and temperature is deteced accuratly except +12V.
The information of sensor is shown below:

That's normal, since you need to have a valid EVEREST license to see the +12V reading on the Sensor page.

Thanks for the feedback!

Thanks for the files, but without having a specification on the sensor registers layout, we cannot further tweak the sensor info for your motherboard It simply has too awkward sensor register layout with possibly non-standard voltage ratios used, so we cannot figure out the tweakings we had to apply.

Thank you, but that's the spec for the sensor chip that we already have on hand. What's the problem about this motherboard (and quite a few others) is that they use custom ratios for sensor registers. The spec itself says sensor registers 22h to 26h are free to use, but there's no standard about what ratios can be applied on them -- and there's no standard on which register means what voltage rail. It could be straightforward (ratio = 1) to measure a voltage in the range of 0.00V to 2.04V. The ratio could be 2x (ratio = 2) to measure a voltage in the range of 0.00V to 4.08V. And if you need a voltage like +5V or +12V to be measured, you need to use a ratio higher than 2 -- but motherboard manufacturers have no fixed (generic) ratio value to use for those rails. Some manufacturers use ratio = 5.26 for +5V, while others use ratio = 5.7 for +5V, etc. It's all a big mess, and unless you have the actual spec of ratios used on a specific motherboard model, you can only guess the sensor registers layout and the ratios used.

[naurto]

Fiery,
The ratio used is 2.THE layout is as below
VIN1= VCORE
VIN2= NB1.05V
VIN3= 5VSB *(1/3.7)
VIN4= DDR1.8V *(10/14.7)
VIN5= VCC *(1/3.7)
VIN6= +12V *(1/11)
Thanks for your help.

Thank you. Are you sure that list is correct? Comparing that list against the BIOS Setup values you wrote above, this list seems to miss +5V reading.

[naurto]

Fiery,
VIN5= VCC *(1/3.7),that VCC means +5V

Jimmy

[Fiery]

VIN5 cannot be +5V, since using 3.7 ratio on it would mean the similar ratio should be used as for 5VSB. And that would also mean that the relevant register values must be very close to each other -- since they both measure cca. 5.0V. However, as you can see on the screen shot above, VIN3 (5VSB) which is register 0x23 has a value of 0xA9; whereas VIN5 (+5V) which is register 0x25 has a value of 0x76. If you use the 3.7 ratio, 5VSB is calculated as (0xA9)*0.008*3.7 = 5.0024V -- which is fine, but +5V would be (0x76)*0.008*3.7 = 3.4928V -- which is too low and so must be incorrect.

So VIN5 is either not +5V, or the ratio you got is not right. If you try to use a ratio that's common on e.g. MSI motherboards with Fintek sensor chips (*5.26), you get a proper voltage for VIN5: (0x76)*0.008*5.26 = 4.96544V. Which BTW is quite close to the value measured by the BIOS Setup that you quoted above (4.961V).

If it's possible, please clear up the registers layout and the ratios. If you want us to contact Jetway directly to clear up the sensor support for this motherboard, please send me a private message.


Thanks,
Fiery

Thank you, but the dump and report wouldn't help about this issue. We need to know the actual registers layout (which register is wired to which voltage rail) with the corresponding voltage calculation ratios used. The list you provided above seems to have a flaw about the +5V rail, as I explained above. If you can fix that information, we can continue improving EVEREST sensor module about your board.

[naurto]

Fiery,
registers layout is below ,register value is shown as dump above
A. The ratio used is 2.
0x20 : VCC3V
0x27 : VSB
0x28 : VBAT
for example:
VCC3V= index 0x20h *2* 0.008 =0xCEh *2*0.008=3.296V

B. The ratio used is 1
0x21 : VIN1= VCORE
0x22 : VIN2= NB1.05V
0x23 : VIN3= 5VSB *(1/3.7)
0x24 : VIN4= DDR1.8V *(10/14.7)
0x25 : VIN5= VCC *(1/3.7) where VCC=+5V
0x26 : VIN6= +12V *(1/11)
for example:
+5V= index 0x25h *3.7* 0.008 =0xAEh *2*0.008= 5.1504V
+12V= index 0x26h *11* 0.008 =0x88h *2*0.008= 11.968V
VCORE= index 0x21h * 0.008 = 0x83h *2 = 1.078V



Thanks for your help.

Thank you. Can you explain the discrepancies between the 2 register dumps you sent? Register 0x25 is quite different there. Shall I just ignore the first dump and focus on the more recent dump?
