If you do not enter the correct password in three attempts, the system displays the message
Invalid Password! Number of unsuccessful password attempts: <x> System Halted!
Must power down.
Even after you shut down and restart the system, the error message is displayed until the correct
password is entered. The following options are exceptions:
• If System Password is not Enabled and is not locked through the Password Status option, you can
assign a system password.
• You cannot disable or change an existing system password.
NOTE: You can use the Password Status option in conjunction with the Setup Password option to
protect the system password from unauthorized changes.

Entering The UEFI Boot Manager

NOTE: Operating systems must be 64-bit UEFI-compatible (for example, Microsoft Windows Server
2008 x64 version) to be installed from the UEFI boot mode. DOS and 32-bit operating systems can
only be installed from the BIOS boot mode.
The Boot Manager enables you to:
• Add, delete, and arrange boot options.
• Access System Setup and BIOS-level boot options without restarting.
To enter the Boot Manager:
1. Turn on or restart your system.
2. Press <F11> after you see the following message:
<F11> = UEFI Boot Manager
If your operating system begins to load before you press <F11>, allow the system to finish booting,
and then restart your system and try again.
