_PT_MBR Structure

typedef struct {
  BYTE ConsChkRtn[446];
  PTE_MBR Partition0;
  PTE_MBR Partition1;
  PTE_MBR Partition2;
  PTE_MBR Partition3;
  BYTE Signature0;
  BYTE Signature1;
} _PT_MBR;

Description

The _PT_MBR structure has the same form as a master boot record. When the MBR is loaded from the device, it will be cast as a _PT_MBR structure so the MBR elements can be accessed.
