Install CPU
This mainboard has dual Socket-370 which support a Celeron
PPGA/FCPGA, a Cyrix MIII, or a/dual FCPGA Pentium III
processors.
Do not try to install a Socket 7 processor in the Socket-370. A
Socket 7 processor such as the Pentium-MMX, or the AMD K5/K6
does not fit in the Socket 370.
The following list notes the processors that are currently supported
by this mainboard.
FCPGA Pentium III: 500~1130MHz, FSB: 100MHz, 133MHz
(using single or dual processors)
PPGA Celeron: 300~700MHz, FSB: 66 MHz (using a single
processor only)
Cyrix MIII: 500~667MHz, FSB: 100MHz, 133MHz (using a
single processor only)
IMPORTANT: The following instructions must be followed or
the machine may crash.
When installing only one processor: a single Intel processor
must be installed in the CPU1 socket; a single Cyrix processor
must be installed in the CPU2 socket.
Do not use different processors with different core speeds and
frontside bus speeds in dual processor configurations.
Installing Socket-370 Processor
Follow the steps below to install a processor on your mainboard.
1. Locate the CPU1/2 and CPUFAN1/2. Pull the locking lever
out slightly from the socket and raise it to the upright position.
2. On the processor, identify the Pin-1 corner by its beveled edge.
3. On the Socket-370, identify the Pin-1 corner. The Pin-1 corner
is at the end of the locking lever when it is locked.
4. Match the Pin-1 corners and insert the processor into the
socket. No force is required and the processor should drop into
place freely.
