Secure Mode - Intel SE7501HG2 Product Manual

Secure Mode

Secure mode refers to a system state where many of the external inputs and outputs are disabled to
prevent tempering. These include PS/2 ports, floppy and on-board video. When secure mode is in
effect, you must enter a password before the system will accept any PS/2 keyboard or mouse input,
except for the password entry. When secure mode is in effect, you cannot turn off the system
power or reset the server from the front panel switches.
Secure mode has no effect on functions enabled via remote server management or power control
via the watchdog timer.
Taking the system out of secure mode does not change the state of system power. In other words, if
you press and release the power button while secure mode is in effect, the system will not be
powered down when secure mode is later removed. However, if the front panel power button
remains depressed while secure mode is removed, the server will be powered off.
Secure mode is configured through the BIOS setup options or through the System Setup Utility.
Hot Key Activation
A hot key combination allows the user to activate secure mode immediately instead of waiting for
the configured inactivity time-out to expire. The hot key combination is configured through Setup.
Either Ctrl-Alt-L or Ctrl-Alt-Z can be configured as valid hot keys.
NOTE
Hot keys work only with PS/2 keyboards.
Secure Boot Mode (Unattended Start)
The Secure Boot mode allows the system to boot and run the operating system without requiring
the user password, even if the user password is set. However, until the user password is entered,
mouse and keyboard input is not accepted (except for password entry). If Secure Boot is enabled,
secure mode is enabled shortly before boot. To prevent unauthorized tampering with any option
ROM based setup utilities, enable the "Option ROM Menu Mask" setting in the security menu.
Using Secure Boot
When secure mode is in effect:
You can boot the server and the operating system will run, but you must enter the user
password to use the keyboard or mouse.
You cannot turn off system power or reset the server from the front panel switches.
Secure mode has no effect on functions enabled via the Server Manager Module or power control
via the real time clock.
