I replaced an Intell pentium I cpu 75 mhz with an Intell pentium cpu 166 mhz...

nothing happens when I power up except a black screen.
this was on a NEC Ready 7022 tower type computer...

what didn't I do right?

It should work if the motherboard supports it. You will need to change the basic clock speed to 66 and the multiplyer to 2.5

If the new CPU has MMX you need to add a VRM if your motherboard doesn't have the required voltage. follow what Lurker1 posted and it should come up fine.

The easiest thing to try first is to move it to a different PCI slot, if that is an option.

Go into bios and disable com 2. That will eliminate the address conflict.

Hi again

Actually 3F8 is the com1 port. If you are not using the com1 port for a mouse (serial connection) go into the system bios and turn it off.
