◆ EFI_RESET_TYPE

Enumeration of reset types.

Enumerator
EfiResetCold 

Used to induce a system-wide reset. This sets all circuitry within the system to its initial state. This type of reset is asynchronous to system operation and operates withgout regard to cycle boundaries. EfiColdReset is tantamount to a system power cycle.

EfiResetWarm 

Used to induce a system-wide initialization. The processors are set to their initial state, and pending cycles are not corrupted. If the system does not support this reset type, then an EfiResetCold must be performed.

EfiResetShutdown 

Used to induce an entry into a power state equivalent to the ACPI G2/S5 or G3 state. If the system does not support this reset type, then when the system is rebooted, it should exhibit the EfiResetCold attributes.
