Step 4 Install Upgrade Processor

Either an upgrade processor, such as an Intel Overdrive® processor or the Intel 80487SX math coprocessor
can be installed in the Upgrade Processor Socket next to the CPU on the motherboard, as shown in the
following illustration of the lower half of the motherboard.
80487SX
An 80487SX math coprocessor can be installed only if the CPU is an 80486SX. If installing an 80487SX, make sure the
80487SX coprocessor speed is the same as the 80486SX speed (20, 25, or 33 MHz).
Upgradeable Processor
U33 can also be used to install a 169-pin Intel upgradeable processor, such as an Intel P23T. The installation process is the
same as installing an Intel 80487SX. When a 169-pin 80487SX or P23T is installed, the outer row of socket pins is
not filled.
A 240-pin Upgrade Processor, such as an Intel P24T, can also be installed.
