If you have replaced the EC and programmed then the problem is not from the EC you need to check the components related to the keyboard

I tried this bios, as well as others above (I don't want to waste your time), with them the effect is either no power or video garbage on external vga. With the original bios, the machine turns on only with a cursor on the screen /can't boot(No video garbage). Is it possible that the video cards of the motherboards are different and an incorrect bios for the machine leads to the wrong addressing. Please rebuild my bios I expect this will solve the problem. Thank you for your help.
