4. EGB board [A] ( x 6, flat cable x 1, all s)
When installing the new EGB
Remove the NVRAM from the old EGB. Then install it on the new EGB after you replace
the EGB. Replace the NVRAM ( "p.3-3 "NVRAM Replacement Procedure"") if the
NVRAM on the old EGB is defective.
Make sure you print out the SMC reports (“SP Mode Data” and “Logging Data”)
before you replace the NVRAM.
Keep NVRAMs away from any objects that can cause static electricity. Static
electricity can damage NVRAM data.
Make sure the NVRAM is correctly installed on the EGB. Insert the NVRAM in the
NVRAM slot with the "half-moon" [B] pointing to the left-hand side.
Make sure that the DIP-switch settings on the old EGB are the same for the new
EGB when. Do not change the DIP switches on the EGB in the field.
