Description
How to enter secure mode:
Setting and enabling passwords automatically puts the system into secure
mode.
If you set a hot-key combination (through the SSU or Setup), you can secure
the system simply by pressing the key combination. This means you do not
have to wait for the inactivity time-out period. See "Security Menu" on
page 40.
When the system is in secure mode:
The system can boot and run the operating system, but mouse and keyboard
input is not accepted until the user password is entered.
At boot time, if a CD is detected in the CD-ROM drive or a diskette in drive A,
the system prompts for a password. When the password is entered, the
system boots from CD or diskette and disables the secure mode.
If you have not yet installed a CD-ROM drive, if there is no CD in the 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.
To leave secure mode:
Enter the correct password(s).
In secure mode, the system will not boot from or write to a diskette unless a
password is entered. To set these features, see "Secure Mode Boot" and
"Floppy Write Protect" in "Security Menu," page 40.
If this protection feature is enabled by the SSU, the power and reset buttons
are disabled when in secure mode.
You can specify and enable an inactivity time-out period of from 1 to
120 minutes. If no keyboard or mouse action occurs for the specified period,
attempted keyboard and mouse input will not be accepted. To set this
feature, see "Secure Mode Timer" in "Security Menu," page 40.
If video blanking is enabled, the monitor display will go blank until the correct
password(s) is entered. To set this feature, see "Video Blanking" in "Security
Menu," page 40.
