ACPI RTC Support
You can configure standard ACPI (Advanced Configuration and Power Interface) tables to determine
whether the operating system should use RTC (Real-Time Clock) for date/time information. Typically,
you should set this option to Disabled (default). Newer operating systems support ACPI tables to
handle date/time information. Older operating systems do not support ACPI tables.
To configure ACPI RTC Support:
1. From the System Utilities screen, select System Configuration→BIOS/Platform Configuration
(RBSU)→Advanced Options→Advanced System ROM Options→APCI RTC Support and press
Enter.
2. Select one of the following options:
• Enabled
• Disabled (default)
3. Press F10 to save your selection.
