Using Security Profile by Device
Security Profile by Device is used to enable or disable user access to the following
devices:
IDE controller When this feature is set to Disable, all devices connected to the
IDE controller (such as hard disk drives or the CD-ROM drive)
are disabled and will not be displayed in the system
configuration.
Diskette Drive Access When this feature is set to Disable, the diskette drive cannot be
accessed.
Diskette Write Protect When this feature is set to Enable, all diskettes are treated as if
they are write-protected. You can read from the diskette, but you
cannot write to the diskette.
To set Security Profile by Device, do the following:
1. Start the Setup Utility program (see “Starting the Setup Utility program” on
page 27).
2. From the Setup Utility program menu, select Security.
3. Select Security Profile by Device.
4. Select the desired devices and settings and press Enter.
5. Return to the Setup Utility program menu and select Exit and then Save

without saving.
Selecting a startup device
If your computer does not start up (boot) from a device such as the CD-ROM,
diskette, or hard disk as expected, use one of the following procedures to select a
startup device.

Device Menu appears, release the F12 key.
Note: If you are using a USB keyboard and the Startup Device Menu does not
display using this method, repeatedly press and release the F12 key
rather than leaving it pressed when turning on the computer.

to begin.
