Before you install extended data out (EDO) memory in a 

Performa or Power Macintosh 5400 computer, you must 

verify that the logic board is EDO-compatible.

There are four ways to verify that a logic board from a 

Performa or Power Macintosh 5400 computer is 

compatible with EDO memory:

• The logic board has soldered-on EDO DRAM

• The logic board has a resistor present at chip U34

• The logic board has 

 

 resistor present at location R77

The details for identifying an EDO-compatible logic board by 

these methods are presented in the following sections.
