Nelp, please with 1.2 upgrade

I am trying to upgrade an Intel D815EEa with a 1.2 Piii and Upgradeware
adaptor, but it has been crashing.

This board, similar to one in a Dell Dimension 4100, has been tested to
work with both the PowerLeap and Upgradeware adaptors. In my case, the
board runs fine with an 800mhz Piii. I have experienced instability when
using the adaptor/1.2 combo, even with the specified Bios P10.

I believe it's must be hardware related, using the adaptor and a 1.2 Piii.
I have
swapped the adapters and 1.2's from my Compaq in an effort to see if it's a
particular adapter, a particular CPU, and no difference. Same for memory
(different speeds, brands, etc..), power supply, hard drives, even
motherboards... no luck. Yet both claim it should work...

The reason I believe it's hardware is because when the system does go dead
(lights still on) or BSOD, it might take minutes, unplugged, before it will go
back on again. Or even a clearing of the CMOS.

It's running fine at 800... but I wish I could resolve the issue....

You guys are experts in this area, can you give me some insight as to where
to look, adjustments to make to the Bios, etc, which has been cleared... and
left at it's defaults, which are automatic,.... thank you!

Are there any jumpers or dip switches on Power Leap's adapter?

I used an Upgradeware slot 1 to s370 adapter on my Toshiba. Had no problems with everything seeing the new processor.

Thanks.. no dip switches, nothing... this is upgradeware's version....

I just came across something.. could it be the cpu is overheating???? I also found something, go into BIOS and change the settings from automatic, to '3' (versus '2'), this is uncharted territory for me.. does it make sense??
