BIOS Flash Utility
The BIOS flash memory update is required for the following conditions:
•New versions of system programs
•New features or options
•Restore a BIOS when it becomes corrupted. 
Use the Phlash utility to update the system BIOS flash ROM.
NOTE: Create a Crisis Recovery Media (such as USB HDD) before you use the Phlash utility.
NOTE: Do not install memory-related drivers (XMS, EMS, DPMI) when you use the Phlash.
NOTE: Please use the AC adaptor power supply when you run the Phlash utility. If the battery pack does not 
contain enough power to finish BIOS flash, the system will not boot as the BIOS is not loaded. 
Perform the following steps to use the Flash Utility:
1.Press F2 during boot to enter the Setup Menu.
2.Select Boot Menu to modify the boot priority order, for example, if using USB HDD to Update BIOS, move 
USB HDD to position 1.
3.Execute the IFLASH.BAT batch file to update BIOS (Read xxxxx.fd to Memory).

General Information
Pre-disassembly Instructions
Before proceeding with the disassembly procedure, make sure that you do the following:
1.Turn off the power to the system and all peripherals.
2.Unplug the AC adapter and all power and signal cables from the system. 
3.Place the system on a flat, stable surface. 
4.Remove the battery pack.
Disassembly Process
The disassembly process is divided into the following stages:
•External module disassembly
•Main unit disassembly
•LCD module disassembly
The flowcharts provided in the succeeding disassembly sections illustrate the entire disassembly sequence. 
Observe the order of the sequence to avoid damage to any of the hardware components. For example, if you 
want to remove the main board, you must first remove the keyboard, then disassemble the inside assembly 
frame in that order.
