Hey Guys, I have a rare AOpen s661FXm-FSN mobo with some damage that I want to fix.

The area around the chipset is damaged. I need some help with the values of the missing resistors first and foremost. R287 and R288 that is. If you have a board like this, or a similar one with the SIS661FX Chipset, it would be lovely if you could measure those for me. A pic might even be enough since the value is printed on them.

Unfortunately there are nearly no pictures of this board out there and they are low quality, plus the chipset cooler is in the way anyway.

The chipset also has some chewed edges and I hope it still works. I might have to order a new one from china or pull one from another donor board if it doesn't. I'll also have to fix those traces in the top right.

Okay, already got a lead from this picture:

Looks like "68X" and "62X" on the resistors. The layout is a bit different there but I'm confident those are the correct ones.
I would like to double check and then I have to find out what ohm values that correlates to.

The retro web pic is from ASUS P5S800-VM board, here's the boardview if you want to check where these resistors are connected.

Great, thanks!
Confirms the value of those resistors as 43,2 and 50 Ohm respectively.

Had a look at the chipset again and I don't think I'll get away without replacing it. But it's easy enough to test now that I've got the resistor values. Just have to actually receive the board first.
