Invoking IPL

To deliberately invoke the IPL, hold the trigger while performing a cold boot by pressing and
holding the Power Key for the required amount of time. If the trigger is pressed when the
terminal is reset, then control is passed to IPL instead of to the Boot Loader. If the trigger is
not pressed, then IPL verifies all mandatory partitions to ensure that they are present, and
verifies the checksum on all checksummed partitions (IPL, Partition Map, Boot Loader,
®
Splash Screen, and Windows CE). If any of these partitions is missing or corrupted, then
control is automatically passed to IPL instead of the Boot Loader, so that the corrupted data
can be reloaded before it causes any problems. If IPL is invoked accidentally, then either reset
the terminal again without holding the trigger, or select Run System option in the baud rate
menu.
When IPL is invoked (by cold booting while pressing the trigger, or by detecting a corrupt
flash partition), IPL sounds the beeper to indicate that IPL has been invoked, and displays the
Copyright Screen.
The terminal displays the copyright screen for three seconds. During this time, IPL is verifying
the Partition Map and the mandatory and checksummed partitions.

The version number on the top of the screen identifies the version of IPL you are using. The
flash type at the bottom of the screen identifies the size and type of flash chip installed in the
terminal, which you need for your TCM script generation. See Defining Script Properties on
page 6-7.
