Operation
Procedures of Password Bypassing and BIOS Recovery.
For
RD and CSD to debug easily, the system provide one hardware DIP switch for
Bypassing Password
Check, and one Hotkey to enable BIOS Recovery.

Description => Bypassing Password Check.
Bypassing
Password Check (SW1):
If the user has set Password (power-on or set-up password) for security reason, BIOS will check password during POST or when
entering the BIOS set-up menu. However, if it is necessary to ignore the
password check, the user may enable DIP SW1 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.
DIP
Switch Location:
RD/CSD
can enable or disable this function by switching the DIP. The Dip switch is
located as shown in the figure below:
Clear
Password
DIP
SW1: Bypassing Password Check is disabled by default. Switching into ON then
powering on the system will force the BIOS to clear Supervisor and User
passwords. The power-on, set-up password, and the HDD password are all cleared.
[Short
R525 to clear password.]
Restore
BIOS by the Crisis Disk
Enable
this function by pressing the combination: Fn+ESC, and pressing the Power
Button. To use this function, it is strongly recommended that the AC adapter is
connected to the system and plug-in to a wall outlet and the Battery is also in
the system. If this function is enabled, the system will force the BIOS to
enter 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. Detailed steps
are as the followings:
- Prepare the Crisis Disk in WinXP
- Insert the Crisis Disk to a USB floppy drive which is attached to the failed machine.
- While the system is turned off, press and hold Fn+ESC, then press Power Button. The system should be powered on with Crisis Recovery process.
- BootBlock BIOS starts to restore the failed BIOS code. Short beeps should be heard when flashing.
- If the flashing process is finished, a long beep should be heard.
- Power down the system after you hear the long beep.
If
the crisis recovery process is finished, the system should be powered on with
the successful BIOS. RD/CSD can then update the BIOS to a workable one by
regular BIOS flashing process.
