  -h -?               Display this help message
  -m [Method]         Batch mode method execution. Default=MAIN

  -da                 Disable method abort on error
  -df                 Disable Local fault handler
  -di                 Disable execution of STA/INI methods during init
  -do                 Disable Operation Region address simulation
  -dr                 Disable repair of method return values
  -ds                 Disable method auto-serialization
  -dt                 Disable allocation tracking (performance)

  -ed                 Enable timer output for Debug Object

  -fi <File>          Specify namespace initialization file
  -fv <Value>         Operation Region initialization fill value

  -l                  Load tables and namespace only
  -r                  Use hardware-reduced FADT V5
  -te                 Exit loop on timeout instead of aborting method
  -to <Seconds>       Set timeout period for AML while loops

  -v                  Display version information
  -va                 Display verbose dump of any memory leaks
  -vd                 Display build date and time
  -vh                 Verbose exception handler output
  -vi                 Verbose initialization output
  -vr                 Verbose region handler output
  -x <DebugLevel>     Debug output level
