1 Pre-operating system management applications You can manage basic settings and features of a system without booting to the operating system by using the system firmware.
System Setup details The System Setup Main Menu screen details are explained as follows: Option Description System BIOS Enables you to configure BIOS settings. iDRAC Settings Enables you to configure the iDRAC settings. The iDRAC settings utility is an interface to set up and configure the iDRAC parameters by using UEFI (Unified Extensible Firmware Interface). You can enable or disable various iDRAC parameters by using the iDRAC settings utility.
Option Description NVMe Settings Provides options to change the NVMe settings. If the system contains the NVMe drives that you want to configure in a RAID array, you must set both this field and the Embedded SATA field on the SATA Settings menu to RAID mode. You might also need to change the Boot Mode setting to UEFI. Otherwise, you should set this field to Non-RAID mode. Boot Settings Provides options to specify the Boot mode (BIOS or UEFI). Enables you to modify UEFI and BIOS boot settings.
Option Description System Model Name Specifies the system model name. System BIOS Version Specifies the BIOS version installed on the system. System Management Engine Version Specifies the current version of the Management Engine firmware. System Service Tag Specifies the system Service Tag. System Manufacturer Specifies the name of the system manufacturer. System Manufacturer Contact Information Specifies the contact information of the system manufacturer.
Option Description System Memory Speed Specifies the system memory speed. System Memory Voltage Specifies the system memory voltage. Video Memory Specifies the amount of video memory. System Memory Testing Specifies whether the system memory tests are run during system boot. Options are Enabled and Disabled. This option is set to Disabled by default. Dram Refresh Delay By enabling the CPU memory controller to delay running the REFRESH commands, you can improve the performance for some workloads.
Processor Settings You can use the Processor Settings screen to view the processor settings and perform specific functions such as enabling virtualization technology, hardware prefetcher, logical processor idling. Viewing Processor Settings To view the Processor Settings screen, perform the following steps: Steps 1. Power on, or restart your system. 2.
Option Description DCU Streamer Prefetcher Enables or disables the Data Cache Unit (DCU) streamer prefetcher. This option is set to Enabled by default. DCU IP Prefetcher Enables or disables the Data Cache Unit (DCU) IP prefetcher. This option is set to Enabled by default. Sub NUMA Cluster Sub NUMA Clustering (SNC) is a feature for breaking up the LLC into disjoint clusters based on address range, with each cluster bound to a subset of the memory controllers in the system.
Option Description Option Description Family-ModelStepping Specifies the family, model, and stepping of the processor as defined by Intel. Brand Specifies the brand name. Level 2 Cache Specifies the total L2 cache. Level 3 Cache Specifies the total L3 cache. Number of Cores Specifies the number of cores per processor. Maximum Specifies the maximum memory capacity per processor. Memory Capacity Microcode Specifies the microcode.
Option Description For AHCI Mode or RAID Mode, BIOS support is always enabled. Option Description Model Specifies the drive model of the selected device. Drive Type Specifies the type of drive attached to the SATA port. Capacity Specifies the total capacity of the drive. This field is undefined for removable media devices such as optical drives. NVMe Settings The NVMe settings enable you to set the NVMe drives to either RAID mode or Non-RAID mode.
NOTE: You must use only the UEFI boot mode in order to boot from NVMe drives. ● BIOS: The Basic Input/output System (BIOS) is a firmware embedded on the system board. When the system is first started, BIOS activates all of the hardware required by the system to boot including chipset, processor and cache, system memory, internal drives, graphics and audio controllers, and internal expansion cards.
BIOS Boot Settings Enables or disables BIOS boot options. UEFI Boot Settings Enables or disables UEFI Boot options. NOTE: This option is enabled only if the boot mode is BIOS. The Boot options include IPv4 PXE and IPv6 PXE. This option is set to IPv4 by default. NOTE: This option is enabled only if the boot mode is UEFI. UEFI Boot Sequence Enables you to change the boot device order. Boot Options Enable/Disable Enables you to select the enabled or disabled boot devices.
Network Settings You can use the Network Settings screen to modify UEFI PXE, iSCSI, and HTTP boot settings. The network settings option is available only in the UEFI mode. NOTE: BIOS does not control network settings in the BIOS mode. For the BIOS boot mode, the optional Boot ROM of the network controllers handles the network settings. Viewing Network Settings To view the Network Settings screen, perform the following steps: Steps 1. Power on, or restart your system. 2.
Option Description Table 1. UEFI iSCSI Settings screen details (continued) Option Description iSCSI device automatically. This is set to by default. iSCSI Device1 Settings TLS Authentication Configuration Enables you to control the configuration of the iSCSI device. View and/or modify this device's boot TLS authentication mode. None means the HTTP server and the client will not authenticate each other for this boot.
Option Description iDRAC Direct USB Port The iDRAC Direct USB port is managed by iDRAC exclusively with no host visibility. This option is set to ON or OFF. When set to OFF, iDRAC does not detect any USB devices installed in this managed port. This option is set to On by default. Internal USB Port Enables or disables the internal USB port. This option is set to Enabled by default. Integrated RAID Controller Enables or disables the integrated RAID controller. This option is set to Enabled by default.
Option Description Table 2. Slot Disablement (continued) Slot Bifurcation Option Description Slot 3 Enables or disables or only the boot driver is disabled for the PCIe slot 3. This option is set to Enabled by default. Slot 4 Enables or disables or only the boot driver is disabled for the PCIe slot 4. This option is set to Enabled by default. Slot 5 Enables or disables or only the boot driver is disabled for the PCIe slot 5. This option is set to Enabled by default.
2. Press F2 immediately after you see the following message: F2 = System Setup NOTE: If your operating system begins to load before you press F2, wait for the system to finish booting, and then restart your system and try again. 3. On the System Setup Main Menu screen, click System BIOS. 4. On the System BIOS screen, click Serial Communication.
System Profile Settings You can use the System Profile Settings screen to enable specific system performance settings such as power management. Viewing System Profile Settings To view the System Profile Settings screen, perform the following steps: Steps 1. Power on, or restart your system. 2.
Option Description Energy Efficient Policy Enables you to select the Energy Efficient Policy option. Number of Turbo Boost Enabled Cores for Processor 1 Monitor/Mwait The CPU uses the setting to manipulate the internal behavior of the processor and determines whether to target higher performance or better power savings. This option is set to Balanced Performance by default.
