Acer Numpad / Numlock Fix

Hello again.
It took me some time but i finaly managed to make my Numlock,Numpad,Numpad LED to work after "upgrade" to Black Edition bios.
This bios has a lot of features and it's great but apparently it's made for a 15" Acer so after the upgrade the system believes that is 15" so no numpad.
So if you have lost your numpad for ANY reason, gives this a try.
Here is what i done to make it work plus some advises.
Indegrients
1)Internet connection (obviously) to download the Windows Automated Installation Kit for (minimum requirements) Windows Server 2003 SP1; Windows XP SP2, Windows Vista OR for Windows 7 Service Pack 1, Windows Server 2008 R2 SP1
2)Usb stick with at least 256mb capacity.
3) This file from Acer
4)Five minutes from your time (and i mean it, you only need 5 minutes to do this work)

Procedure
Download the Windows Automated Installation Kit and extract it using Winrar or whatever, run the file Startcd.exe and then select "Windows AIK Setup"
Complete the installation like you usually do (next, i accept,next,finish) and then click Start, point to All Programs, point to Windows OPK or Windows AIK, right-click Deployment Tools Command Prompt, and then select Run as administrator.

The menu shortcut opens a command-prompt window and automatically sets environment variables to point to all of the necessary tools. By default, all tools are installed at C:\Program Files\<kit>\Tools, where <kit> Windows AIK. We will only use the x86 commands because x64 will not copy WoW64 and therefore it's impossible to run any .exe from the command promt later.

At command prompt type

copype.cmd x86 c:\winpe_x86

copy c:\winpe_x86\winpe.wim c:\winpe_x86\ISO\sources\boot.wim

Now we have to configure our usb ( all contents of the usb will be erased) from the Command Prompt that is already open type

diskpart
List Disk (check carefuly to found your usb)
select disk 1 (Be very careful here, if you select wrong disk, you will lose precious data)
clean
create partition primary
select partition 1
active
format quick fs=ntfs
assign
exit
The example above assumes Disk 1 is the usb.

Copy all of the content in the \ISO directory onto your usb.Use the xcopy command to automatically build and to copy the appropriate files from your technician computer to your usb.

xcopy C:\winpe_x86\iso\*.* /e F:\

Where C is the letter of your hard disk, and F is the letter of your usb
Then type EXIT and hit enter.

Now copy the file we download before from Acer with it's driver (total 2 files) to the root of your USB and then restart.
On post screen you must choose to boot from your usb, after a while you will see a desktop with only command promt running.
On command prompt type
F:
Dir (check if the 2 files from Acer are here, if not try to E: or D: or I: etc)
When you found them type WinKBSel100 and from the application that will run choose EX and close.
Then on command prompt type EXIT, reboot and you are done.
Welcome back your numpad
