Password Protection

BIOS passwords prevent unauthorized tampering with the server. If you set the user
password, but not the administrative password, BIOS requires you to enter the user
password before you can boot the server or run the SSU. If you set both passwords,
entering either password lets you boot the server or enable the keyboard and mouse.
Only the administrative password lets you change the server configuration with the
flash-resident Setup utility.

Secure Boot Mode

Secure boot mode allows the server to boot and run the OS. However, you cannot use
the keyboard or the mouse until you enter the user password.
You can use Setup to put the server in secure boot mode. If BIOS detects a disk in the
CD-ROM drive or a diskette in floppy drive A at boot time, it prompts you for a
password. When you enter the password, the server boots from the disk in the CD-
ROM drive or the diskette in drive A. Entering a password also disables secure mode.
If there is no disk in the CD-ROM drive or diskette in drive A, the server boots from
drive C and automatically goes into secure mode. All enabled secure mode features go
into effect at boot time.
If you set a hot-key combination, you can secure the server 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 SSU
or Setup to select each boot device. The default boot sequence is diskette, hard disk,
CD-ROM, and network.

Boot Without Keyboard

The server can boot with or without a keyboard. Before it boots, BIOS displays a
message keyboard detection. During POST, BIOS automatically detects and tests the
keyboard if one is present.
