DOS header structure

Contains basic information about a DOS executable, the first structure in a PE file. Although modern Windows programs don’t run in DOS mode, the PE format still retains this structure for compatibility.

Fields

e_magic: u16

DOS signature, usually 0x5A4D (“MZ”)

e_cblp: u16

Number of bytes in the last page of the file

e_cp: u16

Total number of pages in the file

e_crlc: u16

Number of relocation items

e_cparhdr: u16

Size of the header in paragraphs

e_min_allocate: u16

Minimum number of paragraphs required

e_max_allocate: u16

Maximum number of paragraphs required

e_ss: u16

Initial SS register value

e_sp: u16

Initial SP register value

e_check_sum: u16

Checksum

e_ip: u16

Initial IP register value

e_cs: u16

Initial CS register value

e_lfarlc: u16

File offset of the relocation table

e_ovno: u16

Overlay number

e_res: [u16; 4]

Reserved fields, usually 0

e_oem_id: u16

OEM identifier

e_oem_info: u16

OEM information

e_res2: [u16; 10]

Reserved fields, usually 0

e_lfanew: u32

File offset of the PE header, pointing to the real PE structure
