Mobile Termina
安装后打开桌面程序
输入：passwd
输入默认密码alpine
然后输入新密码，要输2遍，再继续回到之前的就表示mobile密码已经修改好了
然后在英文状态下输入su回车（就是换行）
输入密码：alpine 输入密码的时候是看不到字符的
如果输入对了，这时候看到屏幕就变成这样：
iPhone:~ mobile$ su
Password:
iPhone:/var/mobile root#
此时输入：passwd
输入新密码，要输2遍，再继续回到iPhone:/var/mobile root#
表示你的root密码已经修改好了
exit退出

苹果分区标识符类型
| Identifier | Contents / file system | Remarks |
|---|---|---|
| Apple_Boot | bootloader | This boot partition is used by Mac OS X when the file system on the main partition is not an Open Firmware conforming HFS partition, such as in a software RAID configuration or when using a HFS+ case-sensitive or a UFS file system. |
| Apple_Bootstrap | NewWorld bootblock | Although it is a general Open Firmware (New World) boot partition, it is specifically used by yaboot. It must be HFS formatted, so that it can be accessed by Open Firmware. |
| Apple_Driver | device driver | Mac OS classic drivers partition |
| Apple_Driver43 | SCSI Manager 4.3 device driver | Mac OS classic drivers partition |
| Apple_Driver43_CD | SCSI CD-ROM device driver | Mac OS classic drivers partition |
| Apple_Driver_ATA | ATA device driver | Mac OS classic drivers partition |
| Apple_Driver_ATAPI | ATAPI device driver | Mac OS classic drivers partition |
| Apple_Driver_IOKit | IOKit driver | Mac OS classic drivers partition |
| Apple_Extra | unused | This identifier masks an unused partition map entry. |
| Apple_Free | free space | This identifier masks free space as a partition map entry. |
| Apple_FWDriver | FireWire device driver | Mac OS classic drivers partition |
| Apple_HFS | Hierarchical File System | While normally a HFS or HFS+ volume for Mac OS and Mac OS X, it can also contain an MS-DOS formatted file system (File Allocation Table, which can be accessed by Mac OS and Mac OS X). |
| Apple_HFSX | HFS Plus | This partition contains a HFS+ volume without a HFS wrapper. HFSX was introduced with Mac OS X 10.3 and is only used in special cases, like case sensitive HFS+. HFSX is the standard partition type on Intel-based Macs (which use GUID instead of APM). |
| Apple_MFS | Macintosh File System | This partition is used by Mac OS for the Macintosh File System (MFS), which was introduced with the Macintosh 128K in 1984. |
| Apple_Partition_Map | partition map | The partition map is also a partition of its own. It can vary in size depending on how many partitions it may contain. |
| Apple_Patches | patches | Mac OS classic patch partition |
| Apple_PRODOS | ProDOS | ProDOS file system |
| Apple_Scratch | empty | This identifier marks an empty partition. |
| Apple_Second | Second stage bootloader | |
| Apple_UFS | Unix File System | This partition contains a Unix File System (UFS) and is used by Mac OS X and various Unix-like operating systems. |
| Apple_UNIX_SVR2 | A/UX | Originally introduced for A/UX (Apple Unix operating system based on System V Release 2, hence SVR2) on the 68k, it was later reused for MkLinux which used the Extended file system. It is the standard partition identifier for many Unix-like operating systems, including Linux and NetBSD. It may contain any file system suitable for the installed operating system. If bootable, a file system that can be read by the Open Firmware bootloader from Apple_Bootstrap (e.g. yaboot) must be used. |
| Apple_Void | ISO9660 padding | A dummy partition map entry to ensure correct partition alignment on bootable media. |
| Be_BFS | Be File System | This partition contains a Be File System (BFS) and is normally used by BeOS. |
苹果系统分区表结构
Apple用一个专门的分区存储分区表项，这个分区就是起始于1号扇区的分区表分区。分区表分区是磁盘的第一个分区，由一系列大小为512-byte的分区表项组成，每个分区表项描述一个分区，包括分区的起始扇区号、分区大小、分区类型以及卷名等信息。除0号扇区外，其余的所有扇区一定属于某个分区表项所描述的空间。
分区表项的数据结构及其含义见表2.7。
