4-1 How to Update BIOS 

Step1.  Prepare  a  boot  disc.  (You  may  make  one  by  click  START  click  RUN  type 

SYS A:      click OK) 

Step2.  Download  upgrade  tools  and  the  latest  BIOS  files  of  the  motherboard  from 

official website and then make a copy of it to your bootable floppy disk after 
decompressing these files 

Step3. Insert the disk into A: 

start your computer and then type in “A:\xxxxxx.BAT” 

(xxxxxxx being the file name of the latest BIOS) 

Step4.  Type  Enter  to  update  and  flash  the  BIOS.  The  system  will  restart 

automatically when BIOS is upgraded. 

4-2 Trouble Shooting 

Problem

 

Solution

 

No  power  to  the  system  to  the  all 
power  light  don‟t  illuminate,  fan  inside 
power supply doesn‟t turn on. 

1.  Make  sure  power  cable  is  security 
plugged  in.  2.  Replace  cable.  3. 
Contact technical support. 

System  inoperative.  Keyboard  lights 
are  on,  power  indicator  lights  are  lit, 
and hard drive is spinning. 

Using  ever  pressure  on  both  ends  of 
the  DIMM,  press  down  firmly  until  the 
module snaps into places. 

System  doesn‟t  boot  from  hard  disk 
drive, can be booted from optical drive. 

1.  Check  cable  running  from  disk  to 
disk  controller  board.  .Make  sure  both 
ends  are  securely  plugged  in,  check 
the  drive  type  in  the  standard  CMOS 
setup.  2.  Backing  up  the  hard  drive  is 
extremely important .All hard disks are 
capable of breaking down at any time. 

System  only  boots  from  optical 
drive  .Hard  disk  can  be  read  and 
applications  can  be  used  but  booting 
from hard disk is impossible. 

1. Back up date and applications files. 
2.  Reformat  the  hard  drive.  Reinstall 
applications  and  date  using  backup 
disks. 

Screen 

message 

says 

“Invalid 

Configuration” or “CMOS Failure” 

Review 

system„s  equipment.  Make 

sure correct information on is in setup. 

Can  not  boot  system  after  installing 
second hard drive. 

1. Set master /slave jumpers correctly. 
2.  Run  SETUP  program  and  select 
correct  drive  types.  Call  the  drive 
manufacture  for  compatibility  with 
other drives.
