+// if this is the first instance, since it's a static linked list.
+// Partition type codes are MBR type codes multiplied by 0x0100, with
+// additional related codes taking on following numbers. For instance,
+// the FreeBSD disklabel code in MBR is 0xa5; here, it's 0xa500, with
+// additional FreeBSD codes being 0xa501, 0xa502, and so on. This gives
+// related codes similar numbers and (given appropriate entry positions
+// in the linked list) keeps them together in the listings generated
+// by typing "L" at the main gdisk menu.
+// See http://www.win.tue.nl/~aeb/partitions/partition_types-1.html
