- `EFI_FVB2_ERASE_POLARITY` (set by default, means that uninitialized data bits in volume are set to 1)
- `EFI_FVB2_ALIGNMENT_16` (set by our `FvAlignment=16` setting)
-Other possible attribute fro FV that you can come across is `FvNameGuid`:
+Similar to FD, the FV has an attribute that defines an address at which flash volume would be mapped to the CPU memory:
+```
+FvBaseAddress = <...>
+```
+And the tokens that define flash block structure:
+```
+BlockSize = <...>
+NumBlocks = <...>

This attribute would lead to the creation of a file of type `EFI_FV_FILETYPE_FFS_PAD` (padding file) with a GUID value in its data. This file would be placed first in the FV.
-And `BlockSize` attribute:

-BlockSize = <...>
