+	 * Word 08 and 09 (pba low and pba high):
+	 * 
+	 * Both of these should be set to 0xFFFF by default, according to the datasheet.
+	 * "nine digit printed board assembly (PBA) number" for intel cards to be stored
+	 * in a 4 byte (read: 2 word) field. 
+	 * 
+	 * Example: if pba number is 123456-003, then word 08 should be 1234h and word 09 becomes 5603.
+	 * Note: 1234 and 5603 above are big endian. In the image it would actually be 34 12 and 0356
+	 * 
+	 * Example: in mine it was (in the image): 08 10 FF FF. That becomes 1008h and FFFFh, or
+	 * basically: 1008FF-0FF. The same was observed in another.
+	 * 
+	 * Setting it to FF FF FF FF should be fine, according to the datasheet.
