AS 1360: BIOS Passwort löschen

[Acavado]

Ich hatte vor kurzem eine Anfrage zum BIOS PW Reset bei einem Aspire 1360 Serie, hier konnte ich leider kein gültiges PW vergeben. Ein Blick in die Unterlagen zeigt, das speziell bei diesem Gerät eine andere Vorgehensweise nötig ist. Also an alle, die ein Problem mit Bios PW und Aspire 1360 Serie haben:


Standard Operation Procedures of DIP Switches for Aspire 1360/1520

For RD and CSD to debug easily, AS1360/1520 provides 2 hardware DIP switches, one for bypassing Password Check, and the other for enabling Boot Block BIOS. Their default settings are as the followings,

DIP
GPIO
Default Setting
Description
SW1
SIO-GPIO13
Disabled (High)
Bypassing Password Check
SW2
SIO-GPIO15
Disabled (High)
Boot Block BIOS​

Bypassing Password Check (SW1): 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 DIP SW1 to bypass password check.
Boot Block BIOS (SW2): 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.

• Location

Aspire 1360/1520 provides two hardware DIP switches under the keyboard. RD/CSD can enable or disable their functions by switching the DIP. The two switches are as the following figure.

​

• Clear Password

DIP SW1: Bypassing Password Check, Disabled by default. Switching it to ON then powering on the system will force the BIOS to clear Supervisor and User passwords. That means both the power-on and setup passwords, and the HDD password are all cleared.

• Restore BIOS by BootBlock

DIP SW2: Enabling BootBlock BIOS, Disabled by default. Switching it to ON then powering on the system will force the BIOS to enter a special BIOS block, called BootBlock. RD/CSD can use this special BIOS code to restore 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,
3.1 Prepare the Crisis Disk in WinXP (Crisis Disk will be released when BIOS V1.0 is released)
3.2 Switch the DIP SW2 of the failed machine to ON
3.3 Insert the Crisis Disk to the failed machine
3.4 Power on the failed machine
3.5 BootBlock BIOS starts to restore the failed BIOS code. Short beeps should be heard when flashing.
3.6 When the Beep sound is heard, switch back the SW2 to OFF.
3.7 When the flashing process is finished, a long beep should be heard.
3.8 Power down the system when Step 3.5 is finished.
When the BootBlock process is finished, RD/CSD can update the BIOS to a workable one by regular BIOS flashing process.

• Other DIP switches: SW3 and SW4 are not used.

• BootBlock function can also be enabled by Phoenix BootBlock printer fixture. (Suggested)
