Installing the Weitek
U89 is the empty 144-pin PGA socket below
the memory slot (J21) and to the left of
the 80486. "WEITEK" is etched on the
motherboard next to the socket. Pin 1 of
the socket has a white diagonal line
across one corner of the square etched on
the motherboard. This corner corresponds
to pin 1 of the coprocessor — also
identified by a diagonally cut corner.
Check for bent pins on the coprocessor.
Gently straighten any bent pins with
pliers. Install the component in the
socket. Align the pins and press the
coprocessor firmly into the socket, making
sure that pin 1 of the coprocessor is
aligned with pin 1 of socket U89.
Test for Math Coprocessor
The BIOS System Configuration screen
appears at the end of POST. If Installed
is not displayed in the Math Coprocessor
field, reinstall the coprocessor. Turn
power off, check the coprocessor
orientation, press the chip firmly in
place and turn the power on. If still not
