2-2 SYSTEM MEMORY CONFIGURATION
• This VIA 693 Apollo Pro Plus motherboard supports 168pin DIMM of 4MB,
8MB, 16MB, 32MB, 64MB and 128MB to form a memory size between
8MB up to 768MB (SDRAM). VIA 693 Apollo Pro Plus chipset provides
“Table-Free” function. It means that users can install DRAM with any
configuration and in any ban , and that is why the DRAM table is not needed
but do remember that the DRAM must be 3.3V type. For 100 / 133MHz
CPU environment, the SDRAM specification must comply with PC-
100 / PC-133 spec.

2-4.1 J2 SWITCH SIGNAL SUMMARY
HDD INDICATOR LED (PIN1 ~ PIN4)
• This connector connects with the hard dis indicator LED on the case.
INFRARED PORT MODULE CONNECTOR (PIN6 ~ PIN10)
• The system board provides a 5-pin infrared connector for an optional wire-
less transmitting and receiving module. Pin 6 through pin 10 are Transmit,
GND, Receive (low speed), Receive (high speed) and Vcc, respectively.
POWER SWITCH (PIN12 ~ PIN13)
• Toggle pin 12 and pin 13 for turning ON/OFF of the power supply. (For ATX
power only)
SUSPEND CONNECTOR (PIN14 ~ PIN15)
• This allows user to manaully place the system into a suspend mode or
“Green” mode, where system activity is decreased to save electricity and
expand the life of certain components when the system is not in use. This

2-pin connector connects to the case- mounted suspend switch. If you do
not have a switch for the connector, you may use the “Turbo Switch”. SMI
is activated when it detects a short to open moment and therefore leaving
it shorted will not cause any problems. This may require one or two presses
depending on the position of the switch. Wa e-Up can be controlled by
setting in the BIOS but the eyboard will always allow wa e-up(The SMI
lead can not wa e up the system). (The BIOS Power Management setting
must be ENABLED)

2-4.2 J3 SWITCH SIGNAL SUMMARY
SPEAKER CONNECTOR (PIN1 ~ PIN4)
• The spea er is a 4-pin connector to connect with the system and the spea er.
RESET SWITCH (PIN5 ~ PIN6)
• The system board has a 2-pin connector for rebooting your computer with-
out having to turn off the power switch. This prolongs the life of the system’s
power supply.
POWER LED (PIN8 ~ PIN10)
• Connect this 3-pin connector to power LED indicator.
