Hi there, What is the procedures to be followed in removing windows 98 operating system and replacing it with windows XP on my computer? Is the process the same as when one is removing windows XP and replacing it with windows 98?

melone, The purpose of the design is to control ONLY BACK UP.

BrianG, Thanks a million for your concern in finding a solution to my design problem.My e-mail address is ijaoga@yahoo.com or ijaoga@hotmail.com.

pebe, I think your post should have been more helpful if you try to find out what hysteresis is all about.

BrianG, Thanks for your response.It seems you did not get my message correct.The word hysteresis suggests that the circuit should have a temporary resistance to change in voltage.The device should still be on if there is a change of voltage from 50V to 47V,but must go off at 46V and below.I...

I am looking for information on the design of a voltage window switch control circuit with hysteresis.The device is expected to control a 50V dc back up power supply for a telecommunication equipment.The device should be able to switch on a dc back up at 50V and off at 46V.The problem i have is...
