FAT

FAT File System

The file allocation table or FAT stores information about the clusters on the disk in a table. There are three different varieties of this file allocation table, which vary based on their size. The system utility that you use to partition the disk will normally choose the correct type of FAT for the volume you are using, but sometimes you will be given a choice of which you want to use. Since each cluster has one entry in the FAT, and these entries are used to hold the cluster number of the next cluster used by the file, the size of the FAT is the limiting factor on how many clusters any disk volume can contain. The following are the three different FAT versions now in use:

FAT16 與 FAT32 的結構

FAT16 和 FAT32 分割區的結構類似。每個 FAT16 分割區依序可分為四部份：保留區域 ( reserved region )、FAT 區域 ( FAT region )、根目錄區域 ( root directory region )以及資料區域 ( file and directory data region )四部份；對 FAT32 分割區而言，沒有根目錄區域，其餘均相同，FAT32 分割區把根目錄視為一個目錄，包含在資料區域內。底下就先探討啟動區域。

FAT ( 檔案配置表 )

在啟動磁區之後，緊接著的是記載著某個檔案佔有那幾個磁叢的一塊區域，稱之為檔案配置表 ( FAT，File Allocation Table )，想當然耳，這個 FAT 是很重要的，如果記載不正確，檔案就無法順利存取，所以 DOS 特別將 FAT 設為兩個，並隨時檢查這兩 FAT 是否相同。

ramfs, rootfs 和 initramfs

檔案所有提到核心 build 的部分，我都解譯成了 Kbuild。
