XPP 5.0: Why does it always ask for the "first" device?

Solution

When programming proms with XPP, many times a design will require more than
one prom to hold its configuration data. Thus, when programming more than
one set of proms, there are two pieces of information that must be kept
track of; which set of proms you are configuring, and which device within
the present set is being configured. For example, assume you want to make
three copies of a 4010 design that takes up two proms. XPP would
program them in this order:

set1, prom1
set1, prom2
set2, prom1
set2, prom2
set3, prom1
set3, prom2

Unfortunately, XPP 5.0 seems to always prompt with "insert the FIRST device to be
programmed", instead of telling you which device within the set you are programming.
In the upper right corner of the screen you will see a "pattern <num> of <total>"
prompt, which indicates the set number you are currently on, and thus which part of
the bitstream data you are programming. In this same area is a message that says
"Programmed: <num>". This tells you which device within the set you are programming.
Use this information and ignore the "insert FIRST device..." message.
