Detailed Description

The Ext2 superblock structure.

The Fat 'superblock', or boot parameter block as we call it normally Note that this is from the FAT whitepaper, so the names are as specified there (in order to avoid confusion) Note also that Superblock32 and Superblock16 could probably go in Superblock as a union (perhaps)
