2 Introduction
PowerLeap™ Installation Guide
* You must set the SW1 DIP switch to run the CPU at triple or quadruple speed. For details, see the
section “Setting the SW1 DIP Switch” later in this guide.
** There are two versions of the 486DX2-66 CPU: 5V and 3.3V/3.45V. You can use the JP1 jumper
switch on the Power Leap™ upgrade to select the correct voltage. For more information, see the
section “Setting the JP1 Jumper Switch” later in this manual.
*** You must use the JP1 jumper switch on the PowerLeap™ upgrade to select the 3.3V/3.45V CPU
voltage setting. For more information, please see the section “Setting the JP1 Jumper Switch” later in
this manual.
**** Please change the motherboard’s onboard clock frequency to 33MHz.
For 80486-20 systems, the PowerLeap™ upgrade will by default
operate at 60MHz (clock-tripled mode) or 80MHz
(clock-quadrupled mode). To change the system to 100/133MHz
performance, you must modify the onboard clock frequency (for
information, refer to your mainboard’s documentation or contact
your system vendor).
