Chapter 5145 Clearing Password Check and BIOS Recovery This section provide you the standard operating procedures of clearing password and BIOS recovery for Aspire 4530/4230. Aspire 4530/4230 provide one Hardware Open Gap on main board for clearing password check, and one Hotkey for enabling BIOS Recovery. Clearing Password Check Hardware Open Gap Description Steps for Clearing BIOS Password Check If users set BIOS Password (Supervisor Password and/or User Password) for a security reason, BIOS will ask the password during systems POST or when systems enter to BIOS Setup menu. However, once it is necessary to bypass the password check, users need to short the HW Gap to clear the password by the following steps: •Power Off a system, and remove HDD, AC and Battery from the machine. •Open the back cover of the machine, and find out the HW Gap on M/B as picture. •Use an electric conductivity tool to short the two points of the HW Gap. •Plug in AC, keep the short condition on the HW Gap, and press Power Button to power on the system till BIOS POST finish. Then remove the tool from the HW Gap. •Restart system. Press F2 key to enter BIOS Setup menu. •If there is no Password request, BIOS Password is cleared. Otherwise, please follow the steps and try again. NOTE: The steps are only for clearing BIOS Password (Supervisor Password and User Password). ItemDescription R347 (RTC_RST) Clear CMOS Jumper
146Chapter 5 BIOS Recovery by Crisis Disk BIOS Recovery Boot Block: BIOS Recovery Boot Block is a special block of BIOS. It is used to boot up the system with minimum BIOS initialization. Users can enable this feature to restore the BIOS firmware to a successful one once the previous BIOS flashing process failed. BIOS Recovery Hotkey: The system provides a function hotkey: Fn+Esc, for enable BIOS Recovery process when system is powered on during BIOS POST. To use this function, it is strongly recommended to have the AC adapter and Battery present. If this function is enabled, the system will force the BIOS to enter a special BIOS block, called Boot Block. Steps for BIOS Recovery by Crisis Disk: Before doing this, one Crisis Disk should be prepared ready in hand. The Crisis Disk could be made by executing the Crisis Disk program in another system with Windows XP OS. Follow the steps below: 1.Power Off system. 2.Insert the Crisis Disk to a USB floppy drive which is attached to the BIOS flash failed machine. 3.In the power-off state, press Fn+Esc and hold them and then press Power Button. The system should be powered on with Crisis BIOS Recovery process. 4.BIOS Boot Block starts to restore the BIOS code from the Crisis floppy disk to BIOS ROM on the failed machine. 5.If the Crisis flashing process is finished, the system will restart. If the Crisis Recovery process is finished, the system should be powered on with successful and workable BIOS. Then a person can update the latest version BIOS for this machine by regular BIOS flashing process.
