Installing Upgrade Processors
The 586TXD is equipped with a
321-pin Zero Insertion Force (ZIF)
socket at location U37 of the sys-
tem board. This socket is designed
for easy removal of an old proces-
sor and easy insertion of an up-
grade processor. The ZIF socket al-
lows you to carefully place the new
processor into its position. If you
need to apply excessive force to in-
sert the processor, you are not in-
stalling the processor correctly.
Warning:
Open the socket only if you are actually installing a processor. The war-
ranty on the original processor will be voided if the S/N seal is broken.
Before proceeding with the upgrade, take note of the following. The mi-
croprocessor and heatsink may be hot if the system has been running.
To avoid the possibility of a burn, power the system off and let the
processor and heatsink cool for 20 minutes.
The 321-pin ZIF socket consists of five rows of pin holes on each side.
To prevent improper processor installation, the ZIF socket has a Plug/
Keying mechanism. Several holes in the socket are plugged so that the
processor will go in only one way. If you cannot easily insert the proces-
sor, verify that pin 1 of the processor is aligned with pin 1 of the socket.
