...and I just add the latest available BIOS (AI61S022.ROM) in a binary format as an attachment in case someone stumbles on this post, instead of the auto-installing .exe file which updates your bios without any warning once you run it.

I have the same motherboard and it won't start. I am working far from home so I don't have much time to do something but there is one thing that interests me: under processor there should be temperature sensor and I see on photos that it looks like about 5 cm tape but on my motherboard it is cutted and only 0,5 - 1 cm left. The question is: will it run without this sensor? When I will come back to home I will finish recap, program new BIOS chip but I would like to know how it is with this temperature sensor.

It should run without the sensor I guess, you'll just have to disable temperature monitoring in the BIOS.

So now I found some time to come back to this mainboard. It is not posting. I replaced all suspected capacitors, checked MOSFETs (4 close to processor), replaced BIOS chip and still no POST. I found that chip U2 on the left side of memory slots is getting very hot, I can't touch it. Symbols on it:
ICS 9179CF-06
9945
CA930565
I cant find any informations (datasheet) about this chip. Maybe somebody can tell me what is this and give some link to datasheet?

...(datasheet)...

maybe https://www.digchip.com/datasheets/parts/data … 9179-06-pdf.php

Thank You very much. Now I have to find this part but I see that it will not be easy. Propably I will have to take it from other damaged motherboard.
