- The serial number stands as a 32 bit number in the boot sector. It is
- interpreted as a hexadecimal number. All programs except microsofts diskcopy
- copy this number direct to the destination disk. Microsofts diskcopy modifies
- these 4 bytes. You can also use any disk editor to change the serial number.
- Norton Disk Editor displays these 4 bytes as "Serial number" so there is no problem
- to change it.
