+/* Record types:
+ *
+ * 00, data record, contains data and 16-bit address. The format described
+ *     above.
+ * 01, End Of File record, a file termination record. No data. Has to be
+ *     the last line of the file, only one per file permitted. Usually
+ *     ':00000001FF'. Originally the End Of File record could contain a
+ *     start address for the program being loaded, e.g. :00AB2F0125
+ *     would make a jump to address AB2F. This was convenient when programs
+ *     were loaded from punched paper tape.
+ * 02, Extended Segment Address Record, segment-base address. Used when 16
+ *     bits are not enough, identical to 80x86 real mode addressing. The
+ *     address specified by the 02 record is multiplied by 16 (shifted 4
+ *     bits left) and added to the subsequent 00 record addresses. This
+ *     allows addressing of up to a megabyte of address space. The address
+ *     field of this record has to be 0000, the byte count is 02 (the segment
+ *     is 16-bit). The least significant hex digit of the segment address is
+ *     always 0.
+ * 03, Start Segment Address Record. For 80x86 processors, it specifies the
+ *     initial content of the CS:IP registers. The address field is 0000, the
+ *     byte count is 04, the first two bytes are the CS value, the latter two
+ *     are the IP value.
+ * 04, Extended Linear Address Record, allowing for fully 32 bit addressing.
+ *     The address field is 0000, the byte count is 02. The two data bytes
+ *     represent the upper 16 bits of the 32 bit address, when combined with
+ *     the address of the 00 type record.
+ * 05, Start Linear Address Record. The address field is 0000, the byte
+ *     count is 04. The 4 data bytes represent the 32-bit value loaded into
+ *     the EIP register of the 80386 and higher CPU.
