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.
DESCRIPTION OF FILES:
---------------------
BOOTSEC.C - this file contains all of the code for the sample
BOOTSEC.H - this file contains the structure declarations for
the BOOTSECTOR and the DISKIO structures
