Introduction to the Kingston SLC/Now!
Cached Processor Upgrade Card
Congratulations on your purchase of the Kingston SLC/Now! Cached Processor Upgrade Card. This guide
will take you through the basic steps of physically installing and configuring the SLC/Now! into your PS/
2 system. This installation guide is written to provide a quick and easy process to install the SLC/Now!
processor upgrade. If you should require any assistance with this procedure, please feel free to contact
Kingston Technical Support at [phone] (U.S. and Canada) or [phone].
The SLC/Now! is a daughter-card upgrade that replaces the 80286 microprocessor in your IBM PS/2 Models
25-286, 30-286, 50, 50z, and 60 with a 386SLC or 486SLC2 processor. There are three models of upgrades
to meet every computing need: 386SLC-20 (20 MHz), 386SLC-25 (25 MHz), and 486SLC2-50 (50 MHz).
Designed by IBM for 100% compatibility, the SLC/Now! provides power and performance for today's most
demanding software applications and graphics-based operating systems.
Several important features of the SLC/Now! are:
❑Performance enhancement of 4-10 times over 80286 PS/2 processors.
❑20 MHz or 25 MHz 386SLC processor.
❑50 MHz 486SLC2 processor running internally at doubled clock rate.
❑Integrated 32-bit-wide8KB cache and cache controller for “no-wait” processing for the SLC/Now!
20 and SLC/Now! 25.
❑Integrated 32-bit-wide 16KB cache and cache controller for the SLC/Now! 50.
❑Easy installation - simply plug the SLC/Now! into the 80286 socket of your IBM PS/2®Models
25-286, 30-286, 50, 50z or 60.
❑Math coprocessor socket supplied on all models (supports 80387SX).
❑Allows you to maintain your investment in your IBM PS/2 at today's performance levels.
❑No need to reinstall or replace your application software, adapter cards or peripherals.
❑Add new applications requiring a more powerful 386 or higher processor.
The cache driver, supplied on the 3.5" diskette included with your upgrade package, allow you to enable the
onboard memory cache for superior system performance. Versions for DOS and OS/2 included.
For OS/2 installations, a 386 or higher processor is needed on PS/2 Models 50, 50z, or 60. This is
accomplished by adding the SLC/Now! processor upgrade. Be aware that,
OS/2 is NOT supported on the Model 25-286 or 30-286
even with an upgraded processor due to design limitations on those systems.

Packaging Materials
The SLC/Now! has been carefully packed in a special anti-static envelope to protect it from static electricity
and shock prior to being shipped to you. Check for damage while unpacking the cached processor upgrade
card. If you notice any damage, notify your place of purchase.
Save all shipping and packaging materials in the event you need to ship these components.
Note: If your SLC/Now! arrives in cold weather, allow it to reach room temperature before
installation in your PS/2.
Important Static Electricity Precautions
Many of the components in your personal computer are sensitive to electrostatic discharge. The following
precautions can help you reduce the possibility of damaging the components in your personal computer.
❑Touchagroundedsurfacebeforehandling anycomponentsbothinsideandoutside yoursystemunit.
If the system unit is connected to a grounded outlet, this can be done by touching the outside chassis
of the system unit.
❑Do not remove your SLC/Now! from the anti-static bag until you are ready to install it in your PS/2.
❑Hold the card by the edges. Avoid touching the components on the card.
❑Do not slide the card or any ICs over any surface.
❑Avoid plastic, vinyl and styrofoam in your work area.

Math Coprocessor
If your system has an 80287 math coprocessor installed, it must be removed prior to installation of the SLC/
Now!. The SLC/Now! supports an Intel 80387SX math coprocessor or any other fully compatible
equilvalent, and fits directly into the SLC/Now!'s 80387SX math coprocessor socket. The clock speed of
the coprocessor should match the clock speed of the 386SLC (20MHz or 25MHz) or the 486SLC2 (use
25 MHz). (Details on installation can be found in the Installation section)
Utility Diskette
Be sure to read the README.TXT file on the utility diskette. It describes the installation procedure and
additional features/options of the Cache Enable programs. This program will enable the SLC/Now!'s
processor cache.
SoftwareCompatibility
With your SLC/Now! installed you should be able to run your previously installed applications without any
changes. In addition, you can now add new applications such as IBM's OS/2TM (for models 50,50z, and 60
only), Microsoft WindowsTM, and many other 386 based applications. If you already have Windows on your
system, you will need to reinstall Windows to enable the 386 enhanced mode features, such as multitasking.
Refer to Appendix C, "Reinstalling Windows" after you have completed the installation.
80286 Sockets
The 80286 microprocessor in the IBM PS/2 Models 50 and 60 is plugged into a Pin Grid Array socket (PGA)
which plugs into corresponding holes on the system board. Kingston provides a chip removal tool for
removing this type of cpu chip (PGA version).
The IBM PS/2 Models 25-286, 30-286, and 50z uses a Plastic Leaded Chip Carrier (PLCC) featuring an
arrangement of metal leads surrounding the perimeter of the processor chip. Kingston includes a PLCC
Extractor for removal of the 80286 microprocessor (PLCC version).

Installing the SLC/Now! Processor Upgrade Card in your
IBM PS/2 Models 25 286 and 30 286.
1. Set the power switch on the system unit to OFF.
2. Set all external power switches off, (i.e. display, printer, etc.).
3. Unplug the system unit’s power cord from the power outlet.
4. Disconnect all power cords from the rear of your machine.
5. Move your keyboard and all external options away from the work area.
6. Position the unit to allow access to the rear.
7. Using a flat-blade screwdriver or the finger grips, remove the cover mounting screws.
8. Unlock the system cover and carefully slide the system unit’s cover away from the rear and to the
front. When the cover will go no further, tilt it up, remove it from the base and set it aside.
9. Unscrew and remove any adapter cards, being careful to note their position.
10. Before removing the 80286 and the 80287 coprocessor, (if a coprocessor is installed), note the
location of Pin 1 on each processor, (identified by either a notch, beveled edge, dot; or a half-circle
on the 80287 coprocessor).
Note: The position of Pin 1 on the 80286 processor socket must match Pin 1 on the SLC/Now!.
11. Using the PLCC Extractor insert the steel tongs into the two notches on the 80286 chip socket, (on
the system board). Squeeze the grips of the PLCC extractor tool together and carefully remove the

d). A description of the 162 error code will appear, followed by a prompt asking if you want "auto
configuration." Answer "Y" (yes), to the reconfigure question.
e). After the system has been reconfigured, remove the back-up reference diskette and reboot the
computer.
18. Turn on power to your PS/2, check that it boots successfully. If it does not, check that the SLC/Now!
is correctly inserted into the 80286 socket with Pin 1 lined up. Check for bent or damaged pins.
19. Once the machine boots correctly, install the setup utility to enable the SLC/Now!'s onboard cache.
