Can this beer removed? Thanks

Smdflea from Badcaps says: kso3=4 (kbout3) , ksi4=13 (kbout12) , ksi7=16 (kbout15) , ksi6=15 (kbout14) , ksi5=14 (kbout13) I don't know if it makes sense but thin Pin count is 28. Pin 23 from top and bottom, both are over 3V - how can that be for the ground? SMDFlea recommendation of of...

Ok I think I found it KSO3 GROUND KSI4 CS/CE KSI5 CLK KSI6 DI KSI7 DO If this is correct, I still can't detect it :( What do I do with VCC? I can see SuperIO Gets turned on due to 3V AW is present so I don't think I need to connect. Any advice?

I don't know what it means, please explain. I'd be very happy. KSO3=23 KSI4=4 KSI7=1 KSI6=2 KSI5=3

I know what you mean by KSO3=23 KSI4=4 KSI7=1 KSI6=2 KSI5=3 KSO3 is going to Keyboard Pin 23. KSI4 is going to Keyboard 4 etc. But where is it going from Keyboard??? Which is which? Clk/DI/DO/VCC/CS etc.

Hi mate, can you clarify? Thanks

Hi ThienBui, you mean kso3= from super Io to rt809f pin 23 using rt809f port expander for example? I'm sorry it's my first time working on super Io. Only 5 wires?

Hi all, I'm having trouble detecting a SuperIO. ENE KB9028 using RT809F which says it supports KB9028. it's programmable through SPI Flash. From schematics I have connected the RT809F as follows. Pin 1 CS to > Pin128, Pin 2 DO to > Pin120, Pin 4 G to Ground. Pin 5 DI to Pin119, Pin 6 CLK to...
