important!

Socket 7 processors (see Specifications
on page 5) can be used on the Trinity
ATX. Please refer to page 14 for the cor-
rect CPU jumper settings for your CPU.
Remember:
• The CPU is a sensitive electronic
component and it can easily be
damaged by static electricity. Do
not touch the CPU pins with your
fingers.
• Before the CPU is installed, the
mainboard must be placed on a flat	Figure 2-6
surface. You should be able to insert
the CPU with minimal, but firm,
pressure. Do not press down hard on the
CPU.

In Figure 2-6, you can see the CPU and the ZIF socket. Notice that the arm of the ZIF socket is up. When this arm is up, the CPU is unlocked from the socket and allows you to remove or install a CPU. As the ZIF socket is keyed to the processor that you are using, you will only be able to install the CPU one way, thus eliminating the chance for error. Pin 1 on the CPU is

denoted by a small dot on one of the corners and Pin 1 on the ZIF socket is denoted by an angled corner. Never force a CPU into a socket. Forcing a CPU to seat will bend the pins on the CPU and possibly damage the motherboard. Check with your vendor or manufacturer for proper voltage selection.

Push down lightly on the CPU, and lower the arm on the ZIF socket to secure the CPU. A squeaking noise is normal as the arm lowers. After the CPU is securely seated, install the appropriate cooling device (Figure 2-7). Tyan strongly recomends a heatsink/fan combination. Consult with your case manufacturer for other cooling options.
