POWER OFF CONTROL SOFTWARE
The motherboard design supports software power off Control feature
through the SMM code in the BIOS under Win95 operating system
environment. This is INTEL ATX form factor feature and you should use
ATX power supply.
First, you should connect the power switch cable (provided by the ATX
case Supplier) to the connector [ PW_ON ] on the motherboard. In the BIOS
screen of “POWER MANAGEMENT SETUP”, choose “User Defined”(or
min power saving or Max power saving) in “POWER MANAGEMENT” and
choose “Yes” in “PM Control by APM”.
In Windows 95 the “ SHUT DOWN “ option , the computer’ s Power will
switch off automatically and put the PC in a suspend mode. A bunking power
light will indicate this. To restart the system , simply press the Power Button.

MEMORY INSTALLATION
No jumper setting is necessary for DRAM setting, BIOS will check
DRAM type and size automatically. B686 main board contains 3 by
168-pin DIMM sockets (DIMM1,DIMM2,and DIMM3) . B686 main
board has table-free ( or auto-bank ) feature and user can install DIMM
into any bank. The three DIMMs Sockets for system memory
expansion from 8MB to 384 MB. Each bank provides 64-bit wide data
path.
