The server can boot and run the operating system, but mouse and
keyboard input is not accepted until the user password is entered.

server boots from CD or diskette and disables the secure mode.
If there is no CD 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.
To leave secure mode: Enter the correct password(s).
