dual processor help

[Verby]

I need to replace 1 processor in a dual proccessor machine. The good one has the following markings:

1000/256/100/1.7v S1
11190025-0324 Philippines

How much needs to match in the replacement chip?

1ghz & the 100 fsb

hard to find.... extremely hard to find.. especially in slot 1 format

the 133 fsb is more common?
