  GCC-H21N Version 1.03 Firmware Update
To update the firmware of the GCC-H21N please refer to the following instructions:

Note: Not following the subsequent update instructions explicitly will result in 
permanent damage to your drive, for which LG will not be responsible.

This firmware update is for drives with original firmware versions below 1.02.
The drives must be original LG branded drives with the Combo Drive
model number GCC-H21N(no OEM units). 

If you have an OEM unit, branded with another manufacturers name, 
please contact that manufacturer for support and firmware updates.

This firmware update is for use only on PC's with Windows Vista, XP, 
Windows 2000, Windows Millennium Edition(ME), or Windows 98.

[Critical Instructions: (to be followed carefully)

1. Connect the drive as "master" by it self, on the secondary IDE controller 
   with no other device on the same IDE cable, making note to set the jumper 
   on the back of the drive to the "master" position.

2. Download the file GCC-H21N_103(EW).ZIP to a folder of your choice. 
   This download includes this "Read me(ew)" text file, as well as the GCCH21N_103.EXE program,
   which will auto-update your drive's firmware.

3. Close all other programs including: screen saver, antivirus and/or power-down programs. 
   (If these programs are not closed, they will try to engage the PC, during the update process,
   thus interrupting the update and damaging the drive).

4. Check the drive to ensure that there is no disk in the tray 
   before you start the update procedure.

5. Go into the folder with the update file and double click the GCCH21N_103.EXE program
   and click the "Upgrade" button so you'll see "NOTE" and then click "OK".
   Firmware upgrade will be automatically started.

6. When the UPGRADE is complete the screen should indicate 
   "Firmware Update Successfully Completed" and advise you to reboot the system.

   The update will be complete, after you reboot your system.

   Do not open any programs or start any system functions during the update, 
   as they will interfere with data transfer and damage the drive. 
   Do not cancel the operation once it has been started or the drive will 
   become permanently damaged, as a result.
