    First you could ask NU to read absolute sectors. When
    absolute sectors are read you can access head 0 track 0 sector 1
    where the master boot sector and partition table resides.

    If you use Turbo C you could try function biosdisk(), the
    syntax is:

      int biosdisk(int cmd, int drive, int head, int track, int
                   sector, int nsects, void *buffer);

    where cmd=2 is read from disk and cmd=1 is write to disk.
    drive is 0x00..0x7f for diskettes and 0x80... for fixed
    disks. Buffer must be large enough to hold nsects of data.

    You can find a good description of biosdisk (and all other TC 
    functions) from The Waite Group's Turbo C Bible from Howard
    W. Sams & Co.
