2-5 SYSTEM MEMORY CONFIGURATION

• This Intel 82443BX motherboard supports 168pin DIMM of 32MB, 64MB,
128MB, and 256MB to form a memory size between 32MB up to 768MB
(SDRAM). Intel 82443BX chipset provides "Table-Free" function. It means
that users can install DRAM with any configuration and in any bank, and
that is why the DRAM table is not needed but do remember that the DRAM
must be 3.3V type. For 100 MHz CPU environment, the SDRAM specifi-
cation must comply with PC-100 / PC-133 spec.

2-6 JUMPER DEFINITION

• The figure below shows the location of the motherboard's jumper blocks.
CAUTION
• Do not move the jumper with the power on. Always turn off the power and unplug
the power cord from the computer before changing the jumper. Otherwise, the
motherboard could be damaged.

2-6.1 ONBOARD (CFAN1/SFAN1/PFAN1)

CFAN1/SFAN1/PFAN1: ONBOARD FAN (12V)
CPU FAN
SYSTEM FAN
CHASSIS FAN
Those connectors support processor/system/chassis cooling fan with
+12V. Those support three pin head connector. When connecting the wire
to FAN connectors, user should give attention that the red wire is the
positive and should be connected to the +12V, the black wire is Ground
and should be connected to GND. If your motherboard has Hardware
Monitor chipset on-board, you must use a specially designed fan with
speed sensor to take advantage of this function.
For fans with fan speed sensor, every rotation of the fan will send out
2 pulses. System Hardware Monitor will count and report the fan rotation
speed.
