Password Jumper
The jumper at pins 5, 6 and 7 controls whether the user and administrative
passwords are retained or cleared during a system reset.
Procedure to clear the current password and then enter a new one:
1. Refer to the “General Procedure to Change Jumper Settings.”
2. Move the Password jumper from pins 5-6 to pins 6-7.
3. Reinstall the side cover for your safety, and connect the power cord to the
system.
4. Turn the system on, and wait for POST to complete. This automatically
clears the password.
5. Turn the system off, and disconnect the power cord.
6. Again, remove the side cover.
7. Move the jumper from pins 6-7 back to pins 5-6.
8. Reinstall the side cover, and connect the power cord to the system.
9. Run the SSU to specify a new password.
Recovery Boot Jumper
The jumper at pins 9, 10 and 11 controls whether the system attempts to boot using
the BIOS programmed in the boot block area of the FLASH memory. This should be
used only if the operational area of the BIOS is corrupted or needs to be upgraded.
Contact your Micron service representative before doing this.
Procedure to disable recovery booting:
1. Refer to the “General Procedure to Change Jumper Setting.”
2. Move the recovery boot jumper from pins 9-10 to pins 10-11.
3. Reinstall the side cover for your safety, and connect the power cord to the
system.
4. Turn the system on, and insert the Flash Memory Update Utility diskette in
drive A. After the system boots, the speaker emits a single beep and the
recovery process starts. This takes about three minutes. When the
recovery process completes, the speaker emits two beeps.
While in the recovery mode, there is no screen display on the monitor. The
keyboard is disabled as the system automatically recovers the BIOS. The following
beep codes describe the recovery status.
