What are the jumpers for I/O 3.3/3.45/3.52
    How to change the I/O voltage of Shuttle569 without changing the core (I want to run my 2.8core/3.3I/O
    to 2.8core/3.45I/O
    And how to make a 3.2core/3.3I/O to 3.52core/3.3I/O?
    What are all ferquency ratios (1.5x,2x,...) supported by K6-2/266, K6-2/300, K6-2/333, K6-2/350?

8 Processors JP43 & SW1
System Clock / Multiplier Vcore / Vio Voltages Auto-Detect Voltages Adjust Manually
Pentium P55C MMX 233 MHz 66 MHz / x 3.5 2.8 V / 3.3 V
Pentium P55C MMX 200 MHz 66 MHz / x 3 2.8 V / 3.3 V
Pentium P54C 200 MHz 66 MHz / x 3 3.3 V / 3.3 V
Pentium P55C MMX 166 MHz 66 MHz / x 2.5 2.8 V / 3.3 V
Pentium P54C 166 MHz 66 MHz / x 2.5 3.3 V / 3.3 V
Pentium P54C 150 MHz 60 MHz / x 2.5 3.3 V / 3.3 V
Pentium P54C 133 MHz 66 MHz / x 2 3.3 V / 3.3 V
Pentium P54C 120 MHz 60 MHz / x 2 3.3 V / 3.3 V
Pentium P54C 100 MHz 66 MHz / x 1.5 3.3 V / 3.3 V
Pentium P54C 90 MHz 60 MHz / x 1.5 3.3 V / 3.3 V
Pentium P54C 75 MHz 50 MHz / x 1.5 3.3 V / 3.3 V Table 2-1 Like as previously section mentioned, HOT-569 provides multiple setting function of CPU on a single jumper group SW1 and jumper JP43. On SW1, the user can set up System Clock, CPU Clock Multiplier and CPU Voltages.
Beside System Clock and CPU Clock Multiplier must adjust manually, CPU voltage can be set to auto-detect and adjust automatically, none of jumper caps are required on SW1-7 to SW1-12.
HOT-569 provides three ways to adjust CPU voltage:
1) Auto-Detecting -- Jumper JP43 set to close(ON), jumper group SW1-7 to SW1-12 set to open (OFF). Setting to AUTO on " CPU Voltage" item in Chipset Setup Feature of BIOS Software. System will auto-detect CPU type and assign proper voltages.
2) Adjust Voltage Manually by BIOS -- Jumper JP43 set to close (ON), jumper group SW1-7 to SW1-12 set to open (OFF). Adjusting voltage from 2.0V to 3.5V on "CPU Voltage" item in Chipset Setup Feature of BIOS Software.
3) Adjust Voltage Manually by SW1-- Jumper JP43 set to open (OFF), adjust voltage on jumper group SW1-7 to SW1-12 manually. Voltage output ranging from 2.8V to 3.52V. "CPU Voltage" item in Chipset Setup Feature of BIOS Software become not available.
Listed tables show the settings for System Clock, Multiplier, Voltages Auto-detecting or Voltages Adjust Manually for each processor.Processor Configurations

10 Manual Adjusting
Table 2-5 System Clock SW1-1 to SW1-3
50 MHz
55 MHz
60 MHz
66 MHz
75 MHz
83 MHz Multiplier SW1-4 to SW1-6
1.5 x
2 x
2.5 x
3 x
3.5 x
4 x
4.5 x
5 x
5.5 x
Table 2-6 For whom like to set up system manually, listed tables show the System Clock, Multi-plier, and Voltage output that HOT-569 can offer.
Table 2-4 shows the System Clock from 50 MHz to 83 MHz. Table 2-5 shows CPU Multiplier from 1.5X to 5.5X. Table 2-6 shows the Voltage output from 3.52V to 2.8V.
Note: 1) For adjusting CPU voltage manually, make sure jumper JP43 open(off). 2) 75MHz and 83MHz are out of Intel chipset specification.


Second I have the manual for your board in a Acrobat format send me your e-mail and I will e-mail you the manual.

I have the manual (printed), and my problem is only with the voltages (bus and multiplier are OK) - I want to change the I/O voltage separetly from core voltage - all described settings are for 3.52 core=I/O, 3.3 core=I/O, 3.3I/O+ 3.2/2.9/2.8/2.2 core (this 6 settings are the official settings of all CPUs supported by the motherboard), but I want to run a CPU with 2.8core AND 3.45 I/O voltage (core like Pentium MMX, I/O like K6(-1)/300)

Will the Shuttle-569 use all of the feutures of an ATX case? (I know it will fit in there and have ATX PS-connectors......)
---------------
I can change the core voltage very well. My problem is in the I/O voltage....
Saying with other words:
Wich jumper changes the I/O voltage between 3.3V, 3.45V, 3.52V without puting the core voltage to 3.3/3.45/3.52 too?
--------------
After 13 September are passing 12 days with no word from you cybergator after my comment.......I know 20 points are little,but in other questions I have gived 3 (!!!) points .... I just don't have many points.....sorry........
So, should I reject your answer? I understand that you have maked work with anserwering, but that info I can find in the manual......and it don't answer my question........
Possibly you have not checked "notification whenever this question is updated "?
I will wait some more time......
