When Redundancy is set to Disabled, either one of the SDMicroSD card can be selected to present itself as mass
Card
storage device by setting it to be primary card. By default primary SDMicroSD card is selected to be SD Card 1. If
SD Card 1 is not present, then the controller will select SD Card 2 to be the primary SDMicroSD card.
OS Watchdog
If your system stops responding, this watchdog timer aids in the recovery of your operating system. When this
Timer
option is set to Enabled, the operating system initializes the timer. When this option is set to Disabled (the

Memory Mapped
When set to 12 TB, the system will map MMIO base to 12 TB. Enable this option for an OS that requires 44 bit
I/O above Base
PCIe addressing. When set to 512 GB, the system will map MMIO base to 512 GB, and reduce the maximum
support for memory to less than 512 GB. Enable this option only for the 4 GPU DGMA issue. This option is set to
56 TB by default.
Slot Disablement
Enables or disables the available PCIe slots on your system. The slot disablement feature controls the configuration
of the PCIe cards installed in the specified slot. Slots must be disabled only when the installed peripheral card
prevents booting into the operating system or causes delays in system startup. If the slot is disabled, both the
Option ROM and UEFI drivers are disabled. Only slots that are present on the system will be available for control.
