HELP! I have a DIP Switch problem.
I own a Soyo KT-600 Dragon Ultra Platinum and put in a Athlon XP-M 2500+ mainly so I could take advantage of the unlocked multiplier (the 2500+ has a FSB of 266 MHz and a 14X multiplier as default). I really like this mobo as it has all the features I want for this rig and would like to continue to use it for a long while. However, this mobo uses a 7-pin micro dip switch (you use a toothpick to set) to set the multiplier for unlocked chips. I cannot get it set to a multiplier higher than 12.5. After testing out several combinations, I notice that when I attempt to set a multiplier over 12.5, that the actual multiplier is set as if pins 1 and/or 7 are ON when they should be OFF. So, I pull the motherboard out and test each pin for continuity in both their ON and OFF positions and sure enough, there's the problem. All the pins show continuity in the ON position and all the pins show no continuity in the OFF position EXCEPT for pin 7, which shows 150 Ohms even when it is supposed to be OFF.
1 = OFF (<-- I know this is backwards, but it is in the manual this way)
0 = ON

The dip switch is soldered directly to the motherboard. I've tried blowing out and around the switch with canned air and have wiggled the pin 7 switch hoping to dislodge whatever is shorting out that pin--all to no avail. I do not want to cut a trace on the board. I've considered trying to cut a pin in between the board and the switch, but there is very little clearance and my smallest wire cutters won't fit in there. I would try unsoldering the faulty switch entirely, but getting all 14 pins unsoldered simultaneously seems beyond my skill and I don't want to order 10 (or whatever the minimum order is) new dip switches from Jameco just to unshort one switch.
If anyone has any experience or ingenious ideas on how I might remedy this situation, I would greatly appreciate it.
The .pdf for this motherboard is here should you want to take a closer look. The DIP switch setting chart is on page 22 of the manual (page 26 in the .pdf).
