Ÿ
Remote Administration is locked and cannot be
unlocked until Enhanced Security is disabled and the
computer is restarted. This prevents the system
programs in the computer from being updated
remotely.
Ÿ
The configuration settings in the Configuration/Setup
Utility program are protected and cannot be changed
until the administrator password has been entered.
Any changes in computer hardware detected by the
system programs in the computer will generate a
configuration error until the administrator password
has been entered.
To enable or disable Enhanced Security:
1. Insert a system programs update diskette into the
diskette drive (drive A). System programs updates
are available at http://www.ibm.com/pc/support/us/
on the World Wide Web.
2. Power-on the computer. If it is powered on, you must
power-off then power-on.
3. The update begins, the computer halts, and you are
prompted for the administrator password (if you have
set an administrator password). The computer
remains in a halted state until the administrator
password is entered.
4. When the administrator password is entered, or if no
administrator password has been set, the update
diskette will continue to run, and you are given the
option of enabling or disabling Enhanced Security.
The choice is automatically recorded in the System
Security menu of the Configuration/Setup Utility
program.
Network settings
This section applies only to computers linked to a network.
The Configuration/Setup Utility program includes settings
that can be enabled and disabled to configure the network
interface in the computer. These settings are:
Ÿ
Flash over LAN (Update POST/BIOS over Network)
Ÿ
Wake on LAN
Flash over LAN (update POST/BIOS
over network)
Note: For local Flash (BIOS/VPD) update, see “Flash
(BIOS/VPD) update procedure” on page 257.
This setting is used to enable or disable the Flash over
LAN feature. When the feature is enabled, the system
programs, in the computer, can be updated remotely from
a network server. If the administrator password is set in
the computer, it does not have to be entered by the server.
