查了一下,关于MBR的定义网上似乎有两种不同说法

A Master Boot Record (MBR), or partition sector, is the 512-byte boot sector
that is the first sector ("Sector 0") of a partitioned data storage
device。。。

The first sector of a hard drive (cylinder 0,header 00, sector 1) is the
master boot record(MBR) sector. It includes 446 bytes of boot code,the disk
partition table (DPT), and a 2-byte end flag (0x55AA). The MBR is
independent of the operating system and is followed by 62 system reserved
sectors,

这样来看,bmr就是整个第一个扇区,512字节~~~
