Introduction

The TOCBLOCK is 512 bytes long. There are four identical copies of this information. There are two contiguous pairs, one at the beginning of the database and one near the end.

The sizes are in sectors and the starts are relative to the start of the database.

At the moment there are two bitmaps, config and log.
