Boot Settings
You can use the Boot Settings screen to set the boot mode to either BIOS or UEFI. It also enables you to specify the boot
order. The Boot Settings only support UEFI mode.
● UEFI: The Unified Extensible Firmware Interface (UEFI) is a new interface between operating systems and platform
firmware. The interface consists of data tables with platform related information, boot and runtime service calls that are
available to the operating system and its loader. The following benefits are available when the Boot Mode is set to UEFI:
○ Support for drive partitions larger than 2 TB.
○ Enhanced security (e.g., UEFI Secure Boot).

Description
Enables or disables the local machine check exception. This
is an extension of the MCA Recovery mechanism providing
the capability to deliver Uncorrected Recoverable (UCR)
Software Recoverable Action Required (SRAR) errors to
one or more specific logical processors threads receiving
previously poisoned or corrupted data. When enabled, the
UCR SRAR Machine Check Exception is delivered only to the
affected thread rather than broadcast to all threads in the
system. The feature supports operating system recovery for
cases of multiple recoverable faults that are detected close,
which would otherwise result in a fatal machine check event.
The feature is available only on Advanced RAS processors.
This option is set to Disabled by default.
