Additional Security Features
Additional server security features are available as options in the SCU and
through main logic board jumpers.
The SCU includes the following setup options to improve sever security:
•
Display <F1> for Setup Message during POST

Setting this op-
tion to disabled prevents unauthorized personnel from entering the
BIOS Setup utility each time your server is turned on or reset. Dis-
play <F1> for Setup Message during POST appears as an <F1>
Setup prompt on your monitor screen each time your server boots.
If you select
Disable
, the server does not inform you when to
press <F1> to enter Setup. You can still enter Setup by pressing
<F1> before POST completes.
•
Floppy Writes

Setting this option to
Disabled
prevents unau-
thorized personnel from writing data to a diskette.
•
Video Blanking

Setting this option to
Enabled
requires a pass-
word to reactivate the monitor after a set period of keyboard inac-
tivity.
•
Reset and Power Switch Locking

Setting this option to
En-
abled
prevents the power and reset switches from being locked
out during secure mode.
Your main logic board’s Enable Flash Write switch (S8C1-3) should also
be set to OFF to prevent unauthorized personnel from loading a new
server BIOS. Loading a new server BIOS might enable someone to over-
ride other server security features or introduce a virus into your server.
