4. How do I transition from RBSU settings to UEFI settings?
The BIOS/Platform Configuration (RBSU) menu replaced the ROM-Based Setup Utility (RBSU). Use this
menu to access and use both UEFI and Legacy BIOS options. See BIOS/Platform Configuration
(RBSU).
5. When would I want to choose Legacy BIOS Mode rather than UEFI Mode as my boot mode, and
vice versa?
Certain situations might require that you operate in Legacy BIOS Mode, such as booting custom OS
images that were installed using legacy boot mode or created using a legacy BIOS system. UEFI Mode
is enabled by default and is required for certain options, including:
• Secure Boot, UEFI Optimized Boot, Generic USB Boot, IPv6 PXE Boot, iSCSI Boot, and Boot from
URL
• Fibre Channel/FCoE Scan Policy
• Booting to a hard disk drive larger than 2.2 TB
• Booting the Embedded User Partition.
6. How do I select between Legacy BIOS and UEFI Mode?
See Selecting the boot mode.
7. How do I determine if a server has UEFI boot options?
See Boot Options.
8. How do I select a boot device?
See Launching the System Utilities. To access the One-Time Boot Menu where you can select an
option for a one-time boot override, do one of following:
• Press F11 during server POST.
• On the System Utilities screen, select One-Time Boot Menu. See One-Time Boot Menu options.
To modify the boot order for all boots, see Changing the UEFI boot order, or Changing the Legacy
BIOS boot order.
9. How do I enable or disable Intel Hyperthreading?
By default, Intel Hyperthreading is enabled. To disable or re-enable this setting, see Enabling or
disabling Intel Hyperthreading.
10. How do I configure the Minimum Processor Idle Power Package State to No Package State?

this setting, see Minimum Processor Idle Power Package C-State.
11. How do I configure the time zone?
