Hi,

If you have set all the board settings to the correct value for the AMD chip,
including the CORE I/O Voltages, and have pc 100 memory installed, I would
say
that without a post the CPU would be bad because the 200 watt power supply
should
be more than adaquate for it.

Is the PC 100 memory the older 8 chip design or the newer 2/4 chip design?
When you
went back to the 166 did you keep the pc100 memory in there when it fired up?

V1.1 Super 7 motherboard.  I have upgraded the Pentium 166 processor to an
AMD K6-2 500 (used & purchased off eBay). This AMD CPU is on the approved
upgrade list within the Soyo manual. I have reset all the required
motherboard jumper settings to correspond with the AMD CPU and have added
memory Dimms capable of 100mz bus speed, but the system will not post. I
get nothing on the monitor. I have checked and double checked the jumper
settings and have even reset them all back to the original settings,
reinstalled the Pentium 166 CPU and booted it up to assure that the AGP
video card was good. Before I assume the AMD processor is bad, my question
is: The Mini AT Enlight PC case I am using only has a 200 watt(max)power
supply. Is it possible that the motherboard and CPU are under
> powered, preventing a post. From what I can find the AMD CPU only
requires 25 watts, so I'm preplexed.

God Bless America!
