ID1, ID2 Jumpers (Master / Slave Selection)
    The interface allows up to two drives (a Master and one Slave) to be 
    attached to the AT/IDE bus. The following table shows the configurations.

DRIVE EMULATES BOTH MASTER AND SLAVE
    Specifies that one 4110A drive can emulate both the Master drive (Drive 0)
    and the Slave drive (Drive 1). This option allows for existing host systems 
    to utilize the full capacity of the drive.
   
    When the drive is configured as both the Master and the Slave, the recomended
    drive type setting in the computer's CMOS memory is as follows:

          Drive 0
          1024 logical cylinders,
          16 logical heads, and
          63 logical sectors.
       This setting yields 528,482,304 bytes.

          Drive 1
          1024 logical cylinders,
          16 logical heads, and
          63 logical sectors.
       This setting yields 528,482,304 bytes.
    
    When the drive is configured as a Master or as a Slave, the 
    recommended drive type parameters are as follows:
 
    Logical Cylinders:        2048       
    Logical Heads:            16      
    Logical Sectors:          63     
    Capacity (bytes):         1,056,964,608

    NOTE:  The capacity of the 4110A drive may exceed the capacity that the 
    host can access. This limitation stems from the communication link between 
    the DOS and the BIOS. A typical limit is:
   
              1024 cylinders, 16 heads, 63 sectors

    NOTE: If you have a machine with a BIOS that supports over 16 heads, you
    can set the drive to be a SLAVE or MASTER with one full partition. 
    To do this, set the drive for:
   
    Logical Cylinders:        512
    Logical Heads:            64
    Logical Sectors:          63
    Capacity (bytes):        1,056,964,608


DRIVE IS MASTER, SLAVE IS PRESENT
     Specifies the Master drive (Drive 0) when two 4110A drives are used in the 
     system. The other drive is the Slave.

DRIVE IS SLAVE
     Specifies the Slave drive (Drive 1) when two 4110A drives are used in the 
     system. The other drive is the Master.

DRIVE IS MASTER
     Specifies the Master drive (DRIVE 0) when one 4110A drive is used in a 
     system.
