Password Protection
If you set the user password but not the administrative password, the BIOS
requires you to enter the user password before you can boot the system or
run the SCU. If you set both passwords, entering either one lets you boot
the system or enable the keyboard and mouse, but only the administrative
password lets you change the system configuration.
Secure Boot Mode
The secure boot mode allows the system to boot and run the operating
system (OS). However, you cannot use the keyboard or mouse until you
enter the user password.
You can use the SCU to put the system into the secure boot mode. If the
BIOS detects a CD in the CD-ROM drive or a diskette in drive A at boot
time, it prompts you for a password. When you enter the password, the
system boots from the CD-ROM drive or diskette drive and disables the
secure mode.
If there is no CD in the CD-ROM drive or diskette in drive A, the system
boots from drive C and automatically goes into secure mode. All enabled
secure mode features go into effect at boot time.
You can set a hot-key combination to secure the system immediately.
Boot Sequence Control
The BIOS security features determine the boot devices and the boot
sequence. They also control disabling writes to the diskette drive in secure
mode. You can use the SCU to select each boot device. The default boot
sequence is diskette, hard disk, CD-ROM, and Network.
Boot Without Keyboard
The system can boot with or without a keyboard. Before boot, the BIOS
displays a message whether it has detected a keyboard or not. During
POST, the BIOS automatically detects and tests the keyboard if it’s present.
Power and Reset Button Lock
If enabled by the Setup Utility, the power and reset buttons are disabled
when in the secure mode.
