Network driver software should not rely on this field to identify the product or its
capabilities.
Current PBA numbers have exceeded the length that can be stored as hex values in
these two words. For these PBA numbers the high word is a flag (0xFAFA) indicating
that the PBA is stored in a separate PBA block. The low word is a pointer to a PBA block.
The PBA block is pointed to by word 0x09.
The PBA block contains the complete PBA number including the dash and the first digit
of the 3-digit suffix. For example:
Older PBA numbers starting with (A,B,C,D,E) are stored directly in words 0x08 and
0x09. The dash itself is not stored nor is the first digit of the 3-digit suffix, as it is
always 0b for relevant products.
PXE Words (Words 0x30:0x3E)
Words 0x30 through 0x3E (bytes 0x60 through 0x7D) have been reserved for
configuration and version values to be used by PXE code.
Boot Agent Main Setup Options (Word 0x30)
The boot agent software configuration is controlled by the NVM with the main setup
options stored in word 0x30. These options are those that can be changed by using the
Control-S setup menu or by using the IBA Intel Boot Agent utility. Note that these
settings only apply to Boot Agent software.
