* 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
