/* This is what Intel Hex files look like:
1. INTEL FORMATS
A. Intel 1
16-bit address-field format, for files 64k bytes in length or less.
DATA RECORD
Byte 1 Header = colon(:)
2..3 The number of data bytes in hex notation
4..5 High byte of the record load address
6..7 Low byte of the record load address
8..9 Record type, must be "00"
10..x Data bytes in hex notation:
x = (number of bytes - 1) * 2 + 11
x+1..x+2 Checksum in hex notation
x+3..x+4 Carriage return, line feed
END RECORD
Byte 1 Header = colon (:)
2..3 The byte count, must be "00"
4..7 Transfer-address (usually "0000")
the jump-to address, execution start address
8..9 Record type, must be "01"
10..11 Checksum, in hex notation
12..13 Carriage return, line feed
B. INTEL 2
MCS-86 format, using a 20-bit address for files larger than 64K bytes.
DATA RECORD
Byte 1 Header = colon (:)
2..3 The byte count of this record, hex notation
4..5 High byte of the record load address
6..7 Low byte of the record load address
8..9 Record type, must be "00"
10..x The data bytes in hex notation:
x = (number of data bytes - 1) * 2 + 11
x+1..x+2 Checksum in hex notation
x+3..x+4 Carriage return, line feed
EXTENDED ADDRESS RECORD
Byte 1 Header = colon(:)
2..3 The byte count, must be "02"
4..7 Load address, must be "0000"
8..9 Record type, must be "02"
10..11 High byte of the offset address
12..13 Low byte of the offset address
14..15 Checksum in hex notation
16..17 Carriage return, line feed
The checksums are the two's complement of the 8-bit sum
without carry of the byte count, offset address, and the
record type.
START ADDRESS RECORD
Byte 1 Header = colon (:)
2..3 The byte count, must be "04"
4..7 Load address, must be "0000"
8..9 Record type, must be "03"
10..13 8086 CS value
14..17 8086 IP value
18..19 Checksum in hex notation
20..21 Carriage return, line feed
Another document reports these additional types:
EXTENDED LINEAR ADDRESS RECORD
Byte 1 Header = colon (:)
2..3 The byte count, must be "02"
4..7 Load address, must be "0000"
8..9 Record type, must be "04"
10..13 Upper 16 bits of address of subsequent records
14..15 Checksum in hex notation
16..17 Carriage return, line feed
START LINEAR ADDRESS RECORD
Byte 1 Header = colon (:)
2..3 The byte count, must be "02"
4..7 Load address, must be "0000"
8..9 Record type, must be "05"
10..13 Upper 16 bits of start address
14..15 Checksum in hex notation
16..17 Carriage return, line feed
The MRI compiler uses this, which is a repeat of type 5:
EXTENDED START RECORD
Byte 1 Header = colon (:)
2..3 The byte count, must be "04"
4..7 Load address, must be "0000"
8..9 Record type, must be "05"
10..13 Upper 16 bits of start address
14..17 Lower 16 bits of start address
18..19 Checksum in hex notation
20..21 Carriage return, line feed. */
