Set SW4 to off,off, popped in a K6-2+450 and
nothing. After frying a K6 I discovered that the voltage at R60/R61 was still at 3.3V.
1) any ideas on tracking down and fixing the
problem?
2) If I do a voltage split hack on it
would anything need to be different from a V1-V3 voltage split hack? Do I move different resistors, use different values, etc.
3) watch out for this problem on other m/b's.

Steve, what processor came with this machine? I have never seen a V3 with a SW4, but it sounds like you could have one. Split voltage must be enabled for a K62 or K63 to work. Remove R60 and R61 upper right side of CPU socket and solder these 0 ohm resistors at R184 and R185 at lower right of CPU socket.
Also check to be sure that R343 is installed over on the far right just above the sodimm socket between the screw hole and the capacitor there.

I had a Rise CPU and SW 4. I assumed it was
a V4 turned SW 4 to off and popped in the K6
which fried it. I took another V4 flipped the switches and tested at R60 and R61 and it
was 1.97 volts. popped a K6+ into it and it's now running WinME just fine (no sound yet but it's running fine).
I'll check the m/b as you suggest. a hardware guy at work says those switches are
cheap and often fail and suspects SW4. Just
to check I'll desolder SW4 and see if the voltage changes. thanks for your help.
I'll let you know what I find out.
