Standard Operation Procedures of Password Bypassing and BIOS Recovery

Bios/KBC update :

The firmware are combined into one binary file and support both DOS and Windows mode update

- DOS mode

DO make sure you have plugged in the AC adapter to prevent flashing failure. Before flashing the BIOS, you should unzip the compressed file to one directory.

  1. Plug in the AC adapter.
  2. Unzip HIC100WW to C:\ HIC100WW.
  3. Boot to pure DOS.
  4. It is better not to load HIMEM.sys (bypass CONFIG.sys).
  5. To flash the BIOS by Phoenix flash utility, use "*.wph" ROM file to update the BIOS via the following command: C:\ HIC100WW \POM.BAT

- Windows mode

DO make sure you have plugged in the AC adapter to prevent flashing failure. Before flashing the BIOS, you should unzip the compressed file to one directory.

  1. Unzip HIC100WW to C:\ HIC100WW
  2. Plug in the AC adapter.
  3. Boot to pure Windows.
  4. To flash the BIOS by WFlash utility to update the BIOS via double click C:\ HIC100WW \Windows\ BIOSV1.00.exe

Password Bypassing and Bios Recovery :

For RD and CSD to debug easily, TM5520/TM5220/EX5420/EX5120/TM7520/TM7220/EX7420/EX7120 provides one hardware PIN pad for Bypassing Password Check, and one Hotkey to enable BIOS Recovery.

  1. PIN pad : To short PIN pad to bypass password check.
  2. Hotkey to enable BIOS Recovery: Fn+ESC, then Power Button, AC+DC coexistence is strongly recommended.

Bypassing Password Check : If the user has set Password (power-on or setup password) for security reason, BIOS will check password during POST or when entering the BIOS setup menu. However, if it is necessary to ignore the password check, the user may enable short PIN Pad to bypass password check.

BIOS Recovery: Boot Block is a special block of BIOS. It is used to boot up the system with minimum BIOS initialization. The user can enable this feature to restore the BIOS to a successful one if previous BIOS flashing process fails.

PIN pad Location

The system board provides one hardware Pin pad under the keyboard pad. RD/CSD can enable this function by shorting this pad. The Pin Pad location should look as the figure below.

Aspire One Reset Bios Password Jumper

1. Clear Password

PIN Pad: Bypassing Password Check

Keep shorting the 2 triangle PIN pad as shown above and then powering on the system will force the BIOS to clear Supervisor and User passwords.

2. Clearing HDD password:

To decode HDD password error code for unlocking hard disk in a DOS environment.

A\> unlock6 XXXXX 00

XXXXX - HDD password error code

Unlock6.exe v1.1 2 May 2003

Choice what kind of the password to be generated:

0.) Exit

  1. Scan code
  2. upper case ASCII Code
  3. Lower case ASCII code Enter your choice:2 (Choose 2) XXXXXXX

XXXXXXX XXXXXXX

Those passwords are master password. 3. Restoring the BIOS through the Crisis Disk

Enable this function by pressing Fn+ESC, and the Power Button. To use this function, it is strongly recommended that the AC adapter is plugged and battery is inserted into the battery slot. If this function is enabled, the system will force the BIOS to enter into a special BIOS block, called BootBlock. RD/CSD can use this special BIOS code to recover the BIOS to a successful one if previous BIOS flashing process fails. However, before doing this, one Crisis Disk should be prepared in WinXP. Follow the steps below:

  1. Prepare the Crisis Disk in WinXP (Crisis Disk will be released when BIOS V1.00 is released)
  2. Insert the Crisis Disk to a USB floppy drive which is attached to the failed machine.
  3. On the power-off state, press Fn+ESC, hold them, then press the power button. The system should be powered on with Crisis Recovery process.
  4. BootBlock BIOS starts to restore the failed BIOS code. Short beeps should be heard when flashing.
  5. If the flashing process is finished, a long beep should be heard.
  6. Power down the system when the above steps is finished.

If the crisis recovery process is finished, the system should be powered on with a successful BIOS. RD/CSD can then update the BIOS to a workable one by regular BIOS flashing process.
