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 reccomended
drive type setting in the computer's CMOS memory is as follows:
Drive0
1024 logical cylinders,
16 logical heads, and
63 logical sectors.
This setting yields 528,482,304 bytes.
Drive1
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.
