2) Unzip the File to a Folder 


3) Insert A blank Floppy in the Floppy Disk Drive


4) Run the .exe File From the Folder


5) Follow The steps dispayed the Wizard TO crate A bootable BIOS Update Floppy Disk


6) Restart the System With The BIOS Update Floppy disk 


7) Restart the system And Enter The Bios To check if it is Updated



Update The BIOS using Flash Update through internet 


1) Check the manufacture And Model of your motherboard E.G Asus P7H55


2) Go to the motherboard Manufacture  Website e.g www.asus.com


 


3) Go to  service  And Select Support


4) in General Download Tab ,Select Motherboard From Product ,Select  LGA1156 Series And Finally Select Model P7H55 From Model 


5) A scren Will Apper Asking for OS. Select The OS Used by The System from Operating System Drop Down Menu 
 

(Note : U Also Find Bios Update Software On Google.com  just Keep  Proper  Motherboard Model Number )



 recover The System From a failed BIOS Update:


 1) Turn Off The power Supply


 2) Open The system case 


3) Locate The flash Recovery Jumper .The Jumper Location Will be Specified In the Motherboard Manual 


4) Set the jumper to the recovary mode.


5) Turn on the power Supply.


6) Insert The BIOS Backup disk in the Floppy Disk Drive


7) Start The System 


8) Shut down The System When The System Prompts You to Restart The System


9) Turn off The Power Supply


10) Set The Flash Recovary jumper To default Mode


11) Close THe System Case


12) Turn On The Supply


13) Start The System With The BIOS Upgrade Disk in The floppy Disk Drive


14) Follow The Step To Upgrade The BIOS 


{ If the update Bios is not compatible with the system you may have to reinstall the previous version of the BIOS back on the System .}

Troubleshooting The monitor solve the problems associated with it The monitor has a Light Emitting Diode (LED) that Glows continuously in Green Color When The system is on And Blinks in amber color when the system is in the stand by mode or is shut down. Problem in displaying the picture on a new monitor may be caused if the monitor may be caused if the monitor is defective .The CRT monitor uses a very high voltage to produce the display image on the monitor screen Be careful while opening the monitor
