/* 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.  */
