Write a program that will read and display the boot sector of the
the floppy drive. The boot sector is sector 0.
Each sector has 512 bytes that you must display. You will have
to review the INT 21h material that is on the CMSC211 web page
and change the default drive to drive A. Then read the first
sector (sector 0) Display the contains in the following form
(all data is fictious):
The first four digits are the offset into the sector and
then there are 16 bytes displayed in a manner that makes
them easy to read. All values are in hexidecimal.
