Software Installation
e). After the system has been reconfigured, remove the back-up reference diskette and reboot the
computer.
17.
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.
18.
Once the machine boots correctly, install the setup utility for Enabling/Disabling the Memory Cache
as outlined below.
Software Installation
The SLC/Now! requires a cache enabling device driver, SLCCARD.SYS to run at optimum performance.
This device driver comes in two versions, DOS or OS/2, depending on which operating system you are using.
If you are running an earlier version OS/2 1.2 or 1.3, you will need to upgrade to version 2.0 or higher. OS/
2 is NOT supported on PS/2 Models 25 286 or 30 286 due to design limitations within those systems. Only
install OS/2 in models 50, 50z, and 60 with SLC/Now! processor upgrades installed.
The DOS driver, SLCCARD.SYS, or the OS/2 driver, SLCOS220.SYS, must be added to your CONFIG.SYS
file to enable the SLC/Now!'s 8K or 16K onboard cache. Follow the appropriate instructions below depending
on your operating system.
Enabling the Cache (DOS version)
The DOS cache control program, SLCCARD.SYS, should be loaded as a device driver in your CONFIG.SYS
file. To add the device driver to your CONFIG.SYS file, do the following:
Step 1. Copy SLCCARD.SYS to the root directory on the hard drive, or to a bootable floppy if you are
booting from a floppy.
Step 2. Using your favorite text editor, add the following line as the first "DEVICE=" line in your
CONFIG.SYS file:
DEVICE=C:\SLCCARD.SYS
To verify the cache has been enabled, run SPEED200.EXE from the Kingston Utility Diskette. This is the
Landmark System Speed Test version 2.0. This program will tested the clock speed of the SLC/Now! and
report a dramatic difference when the cache is enabled. Refer to Appendix A
Speed Test in the back of this manual.
If the processor cache is not enabled, the performance will be considerably less than it was with the 286
microprocessor. Review the steps listed above to verify proper installation of the device driver.
