I guess only chinesse sellers could have it, another option could be to salbage one from a donor board.

Yes, there is on ali : it8671f-a

If someone has one of these IC and is willing to sell, let me know.

Thanks.

Ultra I/O ITE 8671F-A. Was also used on Soyo SY-6BA+/SY-6BB/SY-6VBA133, MATSONIC MS7070S/MS7192S.
You can buy one of those boards and swap over, but Why bother for Abit board with terrible VIA chipset?

It's not Ultra I/O. They named the chip as Giga I/O - I saw it in the datasheet. It's funny 😃

Gigabyte used "customized" versions of the I/O chips. Here https://jucetize.weebly.com/uploads/3/7/2/0/3 … mpatibility.txt you have a compatibility list, I know that your chip is not there but you can se that Gigabyte used "customized" chips, the last I've remplaced was from an AMD 970 board and it was only for Gigabyte. No idea why they do that.
Also; I don't really know if they are customized or only marked diferent.😉

I found a IT8870F-A on a donor board. I can't find the datasheet and I don't know if they are compatible or even pin compatible. Don't want to try and damage de board even more. Anyone has the datasheet for the IT8870F-A?

Sorry, that's at the edge of my knowledge at the moment, but if you just took the chip out of another board, that board should unfortunately at least power up since the I/O chip controls the motherboard's power up.
So it's complicated, unfortunately, but maybe the donor board chip is fine and the problem of the donor board is oder but I don't know how to test these chips. 🙁

No datasheet. At least you can compare GND and VCC contacts of I/O chips of both motherboards. But BIOS should have code to initialize another model of I/O chip. So even if they are fully electrically compatible absence of normal init will prevent normal booting process.

P.S. IT8870F has 128 pins, IT8671F has only 100 pins. So IT8870F is incompatible for the mainboard.
IT8870F probably may be an analog of IT8712F. Because IT8870F is mentioned on ECS P6IWP-Fe but a very similar ECS P6IWF has IT8712F.
