Hello to everyone. Finally after years i was able to register on this web, it was impossible before with my primary mail, dont know why always had problems with activation.
All in all im here and i wanna see if you could help me with this...
I have an atc-1425b motherboard socket 3.
The first time i tested it into the case it worked ok without errors... but i started to make some things and i connected incorrectly the floppy cable leaving a whole row of pins disconnected. After that i always have the error "Floppy disk(s) fail (C0)" at boot.
I read here on vogons that probably i had a bad io controller caused by my mistake with the cable, so i ordered a spare chip Winbond W83787F.
I replaced it and that doesnt worked, still having same issue. Then i tested com ports as i read also that crystal oscilator 24mhz could have gone bad and that would cause this issue but mouse works well under windows and used osciloscope to ensure 24mhz and it also ok...
What could i do now ??
best regards and thanks from advance

Try removing all cards, and disconnect all cables and power from the mobo, and remove the battery. Wait a bit, then put back the bare minimum (power and VGA) and run.
I've seen several behaviors of mobos when you flip floppy or IDE cables.. often this "full disconnect" trick fixes the mobo and gets it out of its tantrum.

Thanks, but that is what I was doing all the time. I always use the minimum amount of hardware possible, only the necessary to boot.
The good news are that I realized after a couple of hours what the problem was... At the beginning it was the controller for sure, I replaced it and I forgot that I disabled the floppy controller from bios...
I enabled it and all worked again... So the io controller replacement seems to have worked.
Thanks again
