Locate the Ethernet ROM on both the new and failing
system modules. The ROM is a 16-pin socketed chip; it

ROM; there is a ROM key (a small notch) at the end of
the chip close to the memory modules.

screwdriver. Put this ROM aside. Lift the chip gradually,
loosening first one end of the chip and then the other.

to bend the pins on the chip. The pins are fragile and
must be intact for you to add the Ethernet ROM to the
replacement system module.
