Difference between .trx and .bin files?

I read the installation Wiki and there is a brief description of the difference between a .trx file and .bin files. It says
The *.bin images are identical to the generic *.trx image, except they have a model-specific header that allows for easy installation.
I would like some further understanding as to what precisely is meant by "model-specific header".

The .bin files are identical to the .trx files, except that there is some extra data at the beginning of the file:
Code: Select all
brcm-2.4 .bin contents:
[extra header bytes] [TRX file data]
The extra header bytes contain data used by particular models of router to validate that the firmware is appropriate for the router. Once installed this extra header is discarded.

firstly We go to linux (ubuntu) and use that command to convert bin to trx
Code: Select all
dd if=openwrt-E2500-v1-squashfs.bin of=openwrt-E2500-v1-squashfs.trx bs=32 skip=1
then copy output file to router tmp directory through SCP or Telnet or FTP and put command
Code: Select all
mtd -r write /tmp/openwrt-E2500-v1-squashfs.trx firmware
remember on the end is 'firmware' ,,,,,, not 'linux'
remember it does not preserve your settings
