NOTES:
1. Refer to the Query Structure Output section and offset 28h for the detailed definition of offset
address as a function of device bus width and mode.
2. BA = Block Address beginning location (i.e., 02000h is block 2’s beginning location when the
block size is 128 Kbyte).
3. Offset 15 defines “P” which points to the Primary Intel-Specific Extended Query Table.
