CPU Installation
The C586VX/E allows for easy installation of CPUs. Make sure all jump-
ers 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 C586VX/E system board and their corresponding PCI Clock and Bus
Clock.
Cache Memory
The C586VX/E system board can support 256KB or 512KB pipeline
burst, direct map write-back cache SRAM installed at locations U22 and
U23 of the system board. Refer to page 6 for the locations of the
SRAMs.
1. Position the SIMM above the socket with the “notch” in the module
aligned with the “key” on the socket.
2. Seat the module at a 45° angle into the bank. Make sure it is com-
pletely seated. Tilt the module upright until it locks in place in the
socket.
