Hi, I've had this board for some time and it came with a 486dx2-66. Now I want to mod the board to use 3.3 volt cpus. After searching over the net I concluded that the needed voltage regulator is a MIC29152 so I've bought a MIC 29302 to be on the safe side if I want to try some overclock. But As I've thought after soldering the voltage regulator and setting the jumpers for 3.45 volts on the cpu socket there are still 5 volts so it seems that the missing resistors near the voltage jumpers are necessary but I can't find a clear enough image of a CH-498B rev 2.0 to know the values of the resistors. I think that the capacitor at C23 is not necessary because on some images I've found it is not present.
So I'm thinking if anyone has the rev 2 board and can take a picture of the zone around the voltage regulator to see the values of R20,R21,R67,R68 and R69.
