Enable keyboard password power-on function (JKB)
The motherboard 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
and set the
keyboard power-on password in the “INTEGRATED PERIPHERALS” section of the BIOS.
Save and exit, then power off your system. In this case, the power button’ s power-on
function has been disabled. The only way to power up the system is to enter the correct
password. If you forget the password, clear CMOS and set it again.
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 the devices con-
nected to the keyboard port, if not, 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
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 set the jumper
and BIOS option again.
Memory Configuration
This motherboard provides two168 pin 3.3V un-buffered DIMM sockets to support a flexible
memory size ranging from 8MB/256MB for SDRAM or from 8MB/512MB for EDO memory.
The following set of rules allows for optimum configurations.
Rules for populating a 440LX memory array:
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.
