• Standard graphical browser, which is enabled by default

• Text browser, which is enabled using Console Redirection

To enable Console Redirection, in System Setup, select System BIOS → Serial Communication screen → Serial Communication, select On with Console Redirection.

NOTE: By default, help text for the selected field is displayed in the graphical browser. To view the help text in the text browser, press <F1>.

Choosing The System Boot Mode

System Setup allows you to specify the following boot modes for installing your operating system:

• BIOS boot mode (the default) is the standard BIOS-level boot interface.

• UEFI boot mode is an enhanced 64-bit boot interface based on Unified Extensible Firmware Interface (UEFI) specifications that overlays the system BIOS.

You must select the boot mode in the Boot Mode field of the Boot Settings Screen of System Setup. Once you specify the boot mode, the system boots in the specified boot mode and you proceed then to install your operating system from that mode. Thereafter, you must boot the system in the same boot mode (BIOS or UEFI) to access the installed operating system. Trying to boot the operating system from the other boot mode will cause the system to halt at startup.

NOTE: Operating systems must be UEFI-compatible to be installed from the UEFI boot mode. DOS and 32-bit operating systems do not support UEFI and can only be installed from the BIOS boot mode.

NOTE: For the latest information on supported operating systems, see dell.com/ossupport.

Entering System Setup

1. Turn on or restart your system.

2. Press <F2> immediately after you see the following message:

<F2> = System Setup

If your operating system begins to load before you press <F2>, allow the system to finish booting, and then restart your system and try again.

If an incorrect system password is entered, the system displays a message and prompts you to re-enter your password. You have three attempts to enter the correct password. After the third unsuccessful attempt, the system displays an error message that the system has halted and will shut down.

Even after you shut down and restart the system, the error message continues to be displayed until the correct password is entered.

NOTE: You can use the Password Status option in conjunction with the System Password and Setup Password options to protect your system from unauthorized changes.

Deleting Or Changing An Existing System And/Or Setup Password

Ensure that the Password jumper is set to enabled and the Password Status is Unlocked before attempting to delete or change the existing System and/or Setup password. You cannot delete or change an existing System or Setup password if the Password Status is Locked.

NOTE: If you change the System and/or Setup password a message prompts you to re-enter the new password. If you delete the System and/or Setup password, a message prompts you to confirm the deletion.

7. Press <Esc> to return to the System BIOS screen. Press <Esc> again, and a message prompts you to

save the changes.

NOTE: You can disable password security while logging on to the system. To disable the password security, turn on or reboot your system, type your password and press <Ctrl><Enter>.

Operating With A Setup Password Enabled

If Setup Password is Enabled, enter the correct setup password before modifying most of the System Setup options.

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.
