Press 1 or 2 to clean the desired password shown on the screen.
The onscreen message determines whether the function is successful or not.
Using Boot Sequence Selector
The Boot Sequence Selector allows the boot order to be changed without accessing the BIOS. To use Boot Sequence Selector, perform the following steps: 1. 2. Enter into DOS. Execute BS.exe to display the usage screen.
Select the desired boot sequence by entering the corresponding sequence. For example, enter BS2 to change the boot sequence to HDD | CD ROM | LAN | Floppy.

Using DMITools

The DMI (Desktop Management Interface) Tool copies BIOS information to EEPROM to be used in the DMI pool for hardware management. When the BIOS displays Verifying DMI pool data it is checking that the table correlates with the hardware before sending to the operating system (Windows, etc.). To update the DMI Pool, perform the following steps: 1. 2. Boot into DOS. Execute dmitools. The following messages report to screen to confirm completion: dmitools /r ==> Read dmi string from bios dmitools /wm xxxx ==> Write manufacturer name to eeprom (max. 16 characters) dmitools /wp xxxx ==> Write product name to eeprom (max. 16 characters) dmitools /ws xxxx ==> Write serial number to eeprom (max. 22 characters) dmitools /wu xxxx ==> Write uuid to eeprom dmitools /wa xxxx ==> Write asset tag to eeprom (max. 32 characters)

The following examples show the commands and the corresponding output information.

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: 1. 2. 3. 4. 5. 6. Power Off the system, and remove HDD, AC and Battery from the machine. Disconnect the RTC Battery cable and locate the J1 jumper. 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: These steps are only for clearing BIOS Password (Supervisor Password and User Password).
