Manual for Advance 5
Enable keyboard password power-on function (JKB)
The mainboard provides the advanced keyboard password power-on function. When
wanting to use this function, set JKB with pin1& pin2 closed.Otherwise, set JKB with pin2
& pin3 closed for disabling this function.
In order to implement this function, it is necessory to set the keyboard power-on password
in the “INTEGRATED PERIPHERALS” section of the BIOS. For detailed information, see the
explantions of “ INTERGATED PERIPHERALS” of BIOS Part.
Note: 1.If wanting to use this function, 5VSB line of the power supply should be
capable of delivering enough current (eg. 200mA) for all devices
connected to the keyboard port, or you can’t power up the system using
the keyboard.
2.If you set JKB with pin2 & pin3 closed, set “POWER ON Function” to
Password/Button, don’t set it to Password, or this will prevent you
from powering up your system.
3. If you encounter the above problems, clear CMOS and reset the jumper
and BIOS option.
Memory Configuration
This mainboard provides three 168 pin 3.3V un-buffered DIMM sockets to support a flexible
memory size ranging from 8MB/384MB for SDRAM or from 8MB/768MB for EDO memory.
Both 66MHz/100MHz SDRAM with SPD and 66MHz EDO DIMMs are supported. The follow-
ing set of rules allows optimum configurations.
l
Using the serial presence detect (SPD) data structure, programmed into an E
2
PROM on
the DIMM, the BIOS can determine the SDRAM’ s size and speed.
l
The DRAM Timing register, which provides the DRAM speed grade control for the entire
memory array, must be programmed to use the timing of the slowest DRAMs installed.
l
Possible SDRAM DIMM memory sizes are 8MB, 16MB, 32MB, 64MB, 128MB in each DIMM
socket.
l
Possible EDO DIMM memory sizes are 8MB, 16MB, 32MB, 64MB, 128MB, 256MB in each
DIMM socket.
