; active partition DBR> Operating SystemPrimary Boot Sector and hard disk partitionIt can be seen from the structure of the primary boot sector that it only contains a 64-byte hard disk partition table. Because each partition information requires 16 bytes, a hard disk using an MBR partition structure (its disk volume type is MS-DOS) can only recognize up to four primary partitions. Therefore, it is impossible for a hard disk to have more than four pri
detected, the partition is the active partition, and the first sector of the active partition (operating system boot record area, Dos boot RECORDER,DBR) is read into the memory address 0000:7c00h.
Check if the 0000:7DFEH-0000:7DFFH (DBR's end flag bit) is equal to aa55h, and if not equal then show: "Missing Operating System" and then stop.
When a partition is detected to satisfy the requirement, the MBR gives control to the corresponding active partition.
