Page 21: Step 3 Install Coprocessor
Step 3 Install Coprocessor The 80386 Mark V Baby Screamer motherboard supports the Weitek WTK3167, Intel 80387, and Cyrix™ 83D87 or other 387- compatible coprocessors. Choosing A Coprocessor The coprocessor must operate at the same frequency as the system microprocessor. The following table lists math coprocessor parts. - Page 22 Step 3 Install Coprocessor, Continued Installing a Cyrix or Intel coprocessor on the Motherboard An Intel 80387 or Cyrix 83D87 coprocessor will fit in the Weitek 121-pin PGA socket. The 80387 and 83D87 are 64-pin PGA- mount coprocessors. Surface-mount coprocessors will not work. When installing the Cyrix or Intel coprocessor, align pin 1 as described for the Weitek (remember, the chamfered edge is on the bottom of the coprocessor), and insert the coprocessor in the center of the socket, leaving the outer set of pin sockets empty.

Page 23: Step 4 Install The Motherboard
Step 3 Install Coprocessor, Continued Test for Math Coprocessor The AMIBIOS displays a System Configuration screen at the end of AMIBIOS POST (Power On Self Test). The math coprocessor will be displayed here. If the Installed message is not displayed, reinstall the coprocessor. Switch off the power, check the orientation of the coprocessor, press the chip firmly to make sure that it is fully inserted, and then power the system up again. - Page 24 Step 4 Install the Motherboard, Continued Step Action Place the chassis for the motherboard on an anti-static mat. Connect the chassis to ground to avoid static damage during installation. Connect an alligator clip with a wire lead to any unpainted part of the chassis. Ground the other end of the lead at the same point as the mat and the wristband.

Page 25: Step 5 Connect The Power Supply
Step 5 Connect the Power Supply The power supply should match the physical configuration of the chassis. Make sure that the power switch is Off before performing this step. Before attaching all components, make sure that the proper voltage has been selected. Power supplies often can run on a wide range of voltages, but must be set (usually with a switch) to the proper range. - Page 26 Step 5 Connect the Power Supply, Continued See the following figure for the location of connectors P2 and P3. AT-compatible power supplies have two 6-pin connectors that are inserted in P2 and P3. The 6-pin connector with 3 red wires and 2 black wires is connected to P3 and the remaining 6-pin connector is connected to P2.
