Step 2 : Confirm Password Type the password again and press . If you forget password, please clear CMOS. (refer to jumper JBAT) Step 3: Set “Security Option” in “BIOS Features Setup” After setting password, enter “Security Option” in “BIOS Features Setup.” There are 2 options “Setup” & “System.” “Setup” will only secure CMOS setup through password. “System” is to secure PC sytem and password is required during system boot-up in addition to CMOS setup.
2. How to Disable “Supervisor Password” & “User Password”. Step 1: Go to CMOS Setup Menu (need to key in password first) Step 2: Enter “Supervisor Password” or “User Password” When it shows “Enter Password”, press the key instead of entering a new password when "ENTER PASSWORD" appears. It will inform “PASSWORD DISABLED PRESS ANY KEY TO CONTINUNE.” Then, press any key as instructed to disable the password.
4-1-11 Save & Exit Setup The "Save & Exit Setup" option will bring you back to boot up procedure with all the changes you have made which are recorded in the CMOS RAM.
4-1-12 Quit Without Saving The "Quit Without Saving" option will bring you back to normal boot up procedure without saving any data into CMOS RAM. All of the old data in the CMOS will not be changed.

Chapter 6 6-1 Q&A Error Messages During Power on Self Test During power on self test (post), BIOS will automatically detect the system devices. Below are the questions that users most often meet. The user may press “Esc” key to skip the full memory test. 1. Beep sound On power on, the system make beep sound to offer different messages. If the system is configured correctly, it prompts a short beep to show device configuration is done correctly.
5. Hard disk initialize Please wait a moment… Some hard drives require more time to initialize. 6. Hard disk install failure The system can not find or initialize the hard drive controller or the drive. Check if the controller is set correctly. If no hard disk is installed, “Hard drive selection” must be set to “none.” 7. Keyboard error or no keyboard present This means the system can not initialize the keyboard. Check if the keyboard is plugged well and be sure no keys are pressed during POST. 8.
