Hey folks !
I came across this really neat way of clearing the contents of the CMOS without opening your box up and removing the cell.Here's what you do
1.Goto the command prompt ( type in c:\command in run)
2.Type the following
c:\DEBUG
-o 70 ff
-o 71 2e
-q
3.Presto...Now your CMOS is a virgin again
I've tried this out in many boxes.Hope this work in yours !
