Package Contents
In addition to this manual, you also receive the following items:
o 486/Now! processor upgrade board.
o IC Removal tool.
o Kingston Utility diskette.
If any item is missing or damaged, contact your Kingston dealer for replacement. Be
sure the items you receive are genuine Kingston Technology products. The printed

Physical Layout
The Kingston Technology 486/Now! Processor upgrade board has 3 different board
type models. Each board type is available with either a 33Mhz DX or 33Mhz SX
version. There is also a 25Mhz SX version for the PS/2 Model 70 and 80 computers.
The first board type, model 486/33PD3, 486/33PS3 or 486/25PS3 support PS/2
Models 70 and 80. See Figure 1-1 and 1-2. The second and third board types support
the PS/2 P70 portable. The 486/33PD3-P70 and 486/33PS3-P70 support the P70
20Mhz model 8573-061. See Figure 1-3 and 1-4. The CPU socket is located to the
right of the SIMM sockets on the system board. The 486/33PD-P70LP and
486/33PS3-P70LP support the 16Mhz model 8573-031 and the 20Mhz model 8573-
121. These system boards have the CPU socket located above the SIMM memory
sockets. This board type also supports the PS/2 Model 5530. See Figure 1-5 and 1-6.

Switch Settings
The 486/Now! contains a 4-switch block (SW1) mounted to the processor upgrade
board. These four switches must be set to your specific computer motherboard's
speed. The IBM PS/2 Model 70 and 80 can have either a 16Mhz, 20Mhz, or 25Mhz
system board. There is only one setting for the P70 Models, but they are listed
separately by board type. Use the following table to determine which motherboard
you have and match the appropriate switch settings to SW1 on the 486/Now! upgrade.

* Note: SW1 Switch 4 default is set to the ON position. This allows the 486/Now processor to run
POST (Power-On-Self-Test) at a fast 486 level. In some cases, an 8603 mouse error will occur because
of the faster speed. Also if an IBM XGA adapter is installed in the system and a display problem occurs,
changing Switch 4 to OFF should correct either problem.

insert the IC removal tool on one side between the 386 CPU chip and the socket.
Gently pry upward to lift just a little, then lift slightly from other side. Alternate
between sides until the chip is completely out of the socket. (Save the 386 CPU chip
so you can re-install it if you ever need to return temporarily to the old configuration).
See Figure 2-1.
Note: You may remove the Fixed Disk Drive, Floppy Drive, Adapter Card, and the
internal holder chassis to clear the area for easier installation.

Remove the back cover.
STEP 4
Remove the 386 CPU chip on the motherboard by using the IC removal tool. Carefully
insert the IC removal tool on one side between the 386 CPU chip and the socket.
Gently pry upward to lift just a little, then lift slightly from other side. Alternate
between sides until the chip is completely out of the socket. (Save the 386 CPU chip
so you can re-install it if you ever need to return temporarily to the old configuration).
See Figure 8-1 below.
STEP 5
Remove the 387 Math-Coprocessor on motherboard, if present, by inserting the IC
removal tool on one side between the 387 FPU chip and the socket. Gently pry upward
to lift just little, then try other side until the chip is completely out of the socket. See
Figure 8-2 below.

STEP 1
Turn on power to start the computer.
STEP 2
The memory test will display in the upper left corner of the screen. After it finishes
testing, two beeps will sound and an error code 162 will appear if: (1) you are
installing a 486/33PD3 DX version (with built-in math coprocessor) where no
previous math-co was installed; or (2) you are installing a 486/33PS3 or 486/25PS3
SX version (does not have math-co) and the 387 math-co has been removed. If a 162
error appears, proceed with Step 3, otherwise you are finished.
STEP 3
Insert your backup IBM® Reference Diskette in drive A and run either AUTOMATIC
CONFIGURATION or, if you have other adapters installed, say "No" to
AUTOMATIC CONFIGURATION and select "Set Configuration" from the Main
Menu. Then go into "Change Configuration." At this point, all you need to do is press
[F10] followed by an [ENTER] to save your configuration. Now use your exit key
(ESC or F3) to back out completely and re-boot your system.
You have now successfully completed the installation of your new 486/Now!
processor upgrade. To verify the performance of the 486/Now!, Kingston has
included the Landmark System Speed Test version 2.0 on the Kingston diskette. To
test the CPU speed, refer to "Appendix A Landmark System Speed Test".
CAUTION:
After powering up, the 486/Now! becomes hot to the touch. If you need to remove it
for any reason, wait until the chip has cooled.

Included on the Kingston Utility Diskette is the Landmark System Speed Test Version
2.0. To test the CPU speed on your new 486/Now!, run SPEED200.EXE from the
DOS prompt. This must be run from a DOS environment. Do not open a DOS
window from OS/2 to run this program. If you do, it will give sporadic speed results.
LANDMARK SYSTEM SPEED (version 2.0) should report the following:

Appendix B System Error Codes
102 SYSTEM BOARD ERROR ON IBM PS/2 MODEL 70-20MHZ.
This error may occur if the battery has been replaced or removed long enough to clear
CMOS setup. With the 486 processor, some machines may experience a 102 error due
to variations in motherboard timings. To correct, re-install the 80386DX Processor
and run AUTOMATIC CONFIGURATION or SET CONFIGURATION from IBM
Reference diskette, then re-install KINGSTON 486/33PD3 or 48625PS3, run
AUTOMATIC CONFIGURATION, and this problem should not occur again.
162 MATH-COPROCESSOR INSTALLED/REMOVED.
To eliminate this error run AUTOMATIC CONFIGURATION or SET
CONFIGURATION from IBM Reference diskette.
225 WRONG SPEED MEMORY ON MODEL 70 - 16MHz
Change switch settings. Refer to M70 16MHz Figure 3 for correct switch settings.
8603 MOUSE INTERRUPT
This error occurs on some mouse devices during Fast POST (Power-On-Self-Test).
Change SW1 Switch 4 to OFF.
SYSTEM KEEPS REBOOTING.
Check SW1 switches for correct configuration setting. See "Switch Settings" on page
5.
VIDEO CHECK ERROR
In some machines using an 8514A Micro Channel Video Adapter you will experience
a long beep during bootup. This is to indicate the CPU is not running at the expected
rate. This video check does not in any way affect the performance or integrity of the
machine.
