3.3 Installation procedure
3.3.1 Processor (Slot 1 and FAN1)
The BD100 Plus motherboard supports single Pentium
®
III/II/Celeron processors. The processor’s
VID pins automatically program the voltage regulator on the motherboard to the required voltage.
The motherboard currently supports processors that run internally from 233 MHz to 500 MHz or
higher.
This process is for motherboards already equipped with the universal retention mechanism.
For Pentium II processors:
a. Lift each of the two retention mechanism brackets so that they stand fully upright.
You should hear a soft “click” sound once each bracket is in the correct upright
position.
b. With the CPU fan facing the DIMM sockets, insert the CPU horizontally into the
retention mechanism, sliding both edges in simultaneously and as “evenly” as
possible. Then, press down gently yet firmly so that the CPU is fully inserted
correctly into the socket.
c. Locate the two CPU lock switches, which are on the top, one on each side of the
CPU just above its respective bracket. With the CPU fan facing you, use
both hands
and grasp the CPU, placing each thumb on top of each lock switch. Then, at the
same time “flip” each lock switch outward in opposite directions (both away from
the CPU fan). You should hear two “click” sounds, one from each switch. This
indicates the CPU is secured into place.
d. To release CPU, grasp the CPU (in the same manner in “c” above) and push both
lock switches inward (toward the CPU fan). You should hear two “click” sounds,
one from each switch. Lift CPU upward and out of the socket.
For Pentium III/Celeron processors:
a. Follow steps “a” ~ “b” above.
b. Locate the two sliding locks on each bracket. Read the writing on each lock:
“OPEN” and “LOCK”. To lock, use your index finger and thumb, grasp each lock,
and gently slide upward. This may be done simultaneously with two hands, or one
at a time. Once each lock has been fixed upward, the CPU is secured into place.
c. To release CPU, use your index finger and thumb, grasp each lock, and gently push
downward. Lift the CPU upward and out of the socket.
Locate the FAN1 header (processor fan header) on the motherboard:
Pin 1 Ground
Pin 2 +12 V
Pin 3 SENSE
Note 1. The processor fan must always be attached to the processor to prevent overheating.
Note 2. The second-level cache is located on the base of the SEC cartridge. The cache size and
cacheable memory size vary, depending on the processor used.
