Did some research and found something curious.
Take a look as this:
As you can see, even on identical 1.6 mobos, the ICS chip has different writings, but the last number is the same on all of them even on the chip of my 1.0 mobo!
I belive the last number is the model of the chip, because it's the only number that match on both 1.6 chips.
And, as you can see, the last number is also the same for my 1.0 ICS chip.
If I'm correct, then the chip of my 1.6 mobo has the same model of my 1.0 one.
And besides, all of them have 24 pins on each side, so it would be a perfect fit.
What do you guys think?EDIT
Never mind, it's indeed the model number.http://www.alldatasheet.com/datasheet-pdf/.../ICS1893AF.html
