(No prompt – not directly user assignable.)

Type: bool

Help

This hidden option enables defining a Task State Segment (TSS) for kernel execution. This is needed to handle double-faults or do privilege elevation. It also defines a special TSS and handler for correctly handling double-fault exceptions, instead of just letting the system triple-fault and reset.
