EXT2 where on disk is the dir_entry structure?

Question

Extended file system

Directories in ext2 are described by the dir_entry structure, which stores the inode number, name, and so on.

Attention, question! Where on disk is this dir_entry structure located? I thought that the link to the block with this structure would be stored in the corresponding inode directory (i_mode&0x4000 != 0), but I was wrong - when I go to i_block[0], I get some strange garbage. Link to the disk image I'm working with

Answer 1

More specifically, what is the problem? Where is the garbage?
I studied the image for interest: at offset 0x5000 (4KiB blocks, 5th block) there is the first inode table, the second entry in it corresponds to the root directory, i_block[0] points to block A5, at offset A5000 we find the dir_entry table:
