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, set “ POWER ON Function” to Password/Button or
Password and set the keyboard power-on password in the “INTEGRATED PERIPHERALS”
section of the BIOS. For detailed information, see the explanations in “ INTERGATED PERIPH-
ERALS” section 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 will be unable to power up the
system using the keyboard.
2.If you set JKB with pin2 & pin3 closed, set “POWER ON Function” to
Password/Button or BUTTON ONLY, 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 two 168 pin 3.3V un-buffered DIMM sockets to support a flexible
memory size ranging from 8MB/512MB. Both 66MHz and 100MHz SDRAM DIMMs are sup-
ported. The following set of rules allows optimum configurations.
l
Do not support registered memory.
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 , 256MB in
each DIMM socket.
