WINDOWS下磁盘根区数据的显示!

BOOTSEC.EXE  - Reads and displays the boot sector of a drive
------------------------------------------------------------

BOOTSEC.EXE version 1.0 (first version) requires Windows 3.1 to run and
the Windows 3.1 SDK to compile and build.

DESCRIPTION:
------------    

BOOTSEC demonstrates how to use INT 25 (absolute disk read) to read 
the boot sector (the first sector on head 0, cylinder 0) off of a
drive (either floppy drive or hard disk).

NOTE:  The information contained in the boot sector was changed 
       in MS-DOS 5.0.  If this program is run on a disk that was
       formatted with a previous version of MS-DOS, then some of
       the fields in the structure will not be filled out, and 
       the program may display garbage.  The elements of the structure
       that were not changed will be displayed correctly.
        

BOOTSEC will check to see if the drive is one of the following:

drive            detection method
-----            ----------------
CD-ROM           INT 2F calls to MSCDEX
Net drive        Windows API WNetGetConnection()
RAM drive        checks the boot sector to see if there is only 1 FAT
Floppy Disk      Windows API GetDriveType()
Hard Disk        Windows API GetDriveType()

BOOTSEC also shows how to implement a dialog box as a main window using
a private dialog class.
