6.3.3.2 Execute Shell Script on Other Harddrive
This example executes the shell script named bootme.nsh located in the root of the first de-
tected disc drive (fs0).
6.3.3.3 Enable Watchdog and Control PXE Boot
The uEFI Shell provides environment variables used to control the execution flow.
The following sample start-up script shows two uEFI Shell environment variables,
wdt_enable
and pxe_first, used to control the boot process and the Watchdog.
To create uEFI Shell environment variables, use the set uEFI Shell command as shown below:
fs0:
bootme.nsh
echo -off
echo “Executing sample startup.nsh...”
if %wdt_enable% == “on” then
kwdt -t 15
echo “Watchdog enabled”
endif
if %pxe_first% == “on” then
echo “forced booting from network”
kboot -t network
endif
