0x0
0x1 ... 0x5
Length in words of the PBA Block (default is 0x6)
PBA Number stored in hexadecimal ASCII values.
The new PBA block contains the complete PBA number and includes the dash and the first digit of the 3-
digit suffix which were not included previously. Each digit is represented by its hexadecimal-ASCII
values.
The following shows an example PBA number (in the new style):

Older NICs have PBA numbers starting with [A,B,C,D,E] and are stored directly in words 0x8-0x9. The
dash in the PBA number is not stored; nor is the first digit of the 3-digit suffix (the first digit is always
0b for older products).
The following example shows a PBA number stored in the PBA Number Module field (in the old style):
