Date and Time: If you select Date and Time from the Configuration/Setup Utility main menu, you can view and change the date and time of the internal clock in your server. Time Date Time shows the time in a 12- or 24-hour format. In a 24-hour 12 midnight is 00:00:00; 12 noon is 12:00:00; 1 p.m. is 13:00:00. Date displays the set date in MM/DD/YYYY format. Note Different countries have different date formats. System Security: If you select System Security from the Configuration/Setup Utility main menu, you can view and, in some cases, change the system security settings for your server. You can use this menu to control access to the hard disk and diskette drives. You can also set, change, and delete power-on and administrator passwords. Enhanced Security If your model has the Enhanced Security feature, this option on the System Security menu shows the current setting for enhanced security. Enhanced security can be enabled or disabled only when you update system programs, as further explained under "Enabling and disabling enhanced security" on page 45. Enhanced security provides extra protection for your administrator password and startup (boot) sequence settings. When enhanced security is enabled, your administrator password and startup sequence are stored in a highly-protected, nonvolatile, security EEPROM module that is separate from CMOS memory and the EEPROM module that stores system programs. When your administrator password and startup sequence are locked in the security EEPROM, they remain intact even if the battery in your server expires or is removed by someone. Secure IDE Devices and Diskette Drives, IDE Controller, Diskette Drive Access. Use this option to enable or disable access to your IDE CD-ROM drive. All IDE devices (such as CD-ROM drives) attached to the IDE controller can be disabled using the IDE Controller field. Diskette drives attached to the system board can be disabled using the 30 Netfinity Server HMM
