Have a look at the following document. It describes the Intel Hex-
Format. Record type 5 means "Start Linear Address Record".
I think that record type 05 indicates the start address of code.

Hello,
I am trying to work on designing a bootloader. For this I
was trying to understand the hex file for LPC. I understood quite a lot
through the link http://www.keil.com/support/docs/1584.htm. But I could not
understand this first line from the hex file itself.
:0400000500000000F7
:020000040000FA
:1000000018F09FE518F09FE518F09FE518F09FE5C0
:1000100018F09FE50000A0E1F0FF1FE518F09FE554
:100020005400000040000000107600004400000072
:1000300048000000000000004C00000050000000DC
I could not find the meaning of code 05. What does it signify? And when I
read the hex file from the controller itself, this line was missing while
other all the lines were same.
Whatever help you all can provide me will be great.
