Chapter 2 Multi-IFBs
Introduction
A Multi-IFB is an IFB package that contains one or more pre-packaged IFB files that execute and delete when
extracted to the target device. Executing an IFB file on the target device extracts that IFB file.
Multi-IFBs need not be digitally signed, unless they contain files (other than IFB files) that require access to
restricted areas on the target device (such as customer script files). Each IFB is treated as a separately signed
IFB. For example, if you have a system update IFB (digitally signed by Symbol) and a customer script IFB
(digitally signed by the customer) packaged together in one unsigned Multi-IFB, the system update IFB and the
script IFB expand properly even though they were contained in an unsigned Multi-IFB. Likewise, if you create a
customer signed Multi-IFB that contains an unsigned customer script, the script cannot install on the target
device even though it was contained in a customer signed Multi-IFB.
PD8500 Multi-IFB Support
PD8500 devices with system version 3.20 offer complete support for Multi-IFBs. PD8500 devices with system
version 3.16 do not support the Multi-IFB \temp root folder. PD8500 devices with system versions older than
3.16 do not support Multi-IFB.
