8284 Clock Generator using an external source for its frequency

Modify the following  8284A clock generator circuit if it will be using an external frequency from another source.


EFI - changed from earth to the OSC input from other 8284A (EFI=external frequency input)
F/C' - changed from earth to Vcc (5v) because now the chip is using F(requency) input instead of C(rystal) input
Both X1 & X2 - grounded

Illustrated here
