used to control the

To create a uEFI Shell environment variable, use the
set
uEFI Shell command as shown below:
fs0:
bootme.nsh
echo -off
echo “Executing sample startup.nsh...”
if %wdt_enable% == “on” then
kwatchdog -t 15
echo “Watchdog enabled”
endif
Shell> set wdt_enable on
Shell> set
wdt_enable : on
Shell> reset
