CPU Installation
The 586IHX allows for easy installation of CPUs. Make sure all jumpers are
set correctly before applying power or you may damage the CPU or system
board. Please see the jumper settings on the following pages. Use the
needle-nosed pliers to move the jumpers if necessary. The table below
shows the External Bus Clock of the CPUs supported by the 586IHX sys-
tem board and their corresponding PCI Clock and Bus Clock.
Installing the Cache Module
Locate the 160-pin cache module slot on the system board (SSM1). Po-
sition the cache module above the slot. Make sure pin 1 of the cache
module is aligned with pin 1 of the slot. Carefully slide the module into
the slot. Press firmly on the top of it to seat it properly.
Warning:
We highly recommend that you use the T2BSM32-256 or T3BSM256
cache module. If you are using a cache module other than one recom-
mended above, make sure your cache module meets the Intel COAST
2.x or 3.x specification. Severe damage might occur on the cache mod-
ule or system board if you insert modules other than those specified
above.
