The length of the data to be substituted in the firmware is not equal to
the length of the corresponding item in the PDA.  The Intersil
documentation says it's not OK, but it looks like they allow some
sloppiness in their own designs.

PDR 1 is present only in the primary firmware:

This means that the length of the data is 16 bytes.  Your PDA provides
only 12 bytes.  I've seen it myself and I haven't had any problems with
such cards.

Since PDR 1 is merely the manufacturing part number, it shouldn't be a big

If you find address 0x7E14CC in the primary firmware, you'll see that all
16 bytes starting at that address are binary zeroes.  The first 12 bytes
are filled with the data from the PDA.  The rest are zeroes.
