Preface
Before using this information and the product it supports, please read the following general information. 1. This Service Guide provides you with all technical information relating to the BASIC CONFIGURATION decided for Acer's "global" product offering. To better fit local market requirements and enhance product competitiveness, your regional office MAY have decided to extend the functionality of a machine (e.g.add-on card, modem, or extra memory capability). These LOCALIZED FEATURES will NOT be covered in this generic service guide. In such cases, please contact your regional offices or the responsible personnel/channel to provide you with further technical details.
2. Please note WHEN ORDERING FRU PARTS, that you should check the most up-to-date information available on your regional web or channel. If, for whatever reason, a part number change is made, it will not be noted in the printed Service Guide. For ACER-AUTHORIZED SERVICE PROVIDERS, your Acer office may have a DIFFERENT part number code to those given in the FRU list of this printed Service Guide. You MUST use the list provided by your regional Acer office to order FRU parts for repair and service of customer machines.

1. Initialize MCU settings, including I/O, Timer, ISR and Serial Port settings. 2. Read EEPROM content to recover monitor settings, including brightness, contrast, color temperature and OSD position .... etc. 3. Initialize system variable, including system flag, OSD timeout counter, burin mode status... etc. 4. Initialize OSD menu variable for user operation 5. Initialize device on the board, now only MST scaler chip will be initialized 6. Check if system is in power off status from first AC power up. If yes, then go to 7, else go to 8. 7. If yes, system will be forced to enter power off status 8. Mode detection 9. Check if input timing has been changed, if yes then go to 10, else go to 11 10. Setup MST scaler for display according input timing 11. OSD handler for OSD operation. 12. Debug handler, only debug only
