Hardware Installation Model 60
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. Check for bent or damaged pins.
19.
Once the machine boots correctly, install the setup utility for Enabling/Disabling the Memory
Cache. Continue with the "Software Installation" section on page 13.
Installing the SLC/Now! Processor Upgrade Card in your
IBM PS/2 Model 60
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.
Place the PS/2 Model 60 on its side and unlock the side panel.
7.
Tilt the side panel and remove from the base. Set the side panel aside.
8.
Unscrew and remove any micro channel adapter cards, being careful to note their position.
9.
Before removing the 80286 and the 80287 math 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!.
10.
Using the IC chip removal tool, gently but firmly insert the edge of the tool under a corner of the
processor between the chip and the socket and pry upward to loosen it from the socket. Repeat this
action for all four corners until you are able to remove the microprocessor by hand. Carefully remove
the chip. (Save the 80286 microprocessor in the event you need to temporarily return to the old
configuration.)
11.
If you have an 80287 coprocessor installed, this must also be removed. Locate the 80287 coprocessor
as shown in figure 7 and insert the IC removal tool under the corner of the chip. Gently pry upwards,
repeat for all 4 corners. Once the pins have been sufficiently exposed remove with your fingers. (Save
the 80287 microprocessor in the event you need to temporarily return to the old configuration.)
12.
If you are adding an 80387SX math coprocessor, identify pin 1 of the math coprocessor chip,
(designated by either a beveled edge, dot, notch or half-circle). Match this corner to the bevelled edge
for the math coprocessor on the 386SLC or the 486SLC2 Cached Processor Upgrade Card. Note the
