Quantum IDE disk drives have multiple jumper setting options and are
used to set specific drive features. The most common settings are
used to define the drive as the primary or secondary drive on the
IDE cable.
Master / Slave
--------------
Quantum IDE drives have additional jumper settings used for optional
features found on the drive. Listed below are the various jumper
options that may be found on Quantum IDE drives and the corresponding
feature that they enable.
DS Jumper - Drive Select
------------------------
Used to identify the drive as the primary (MASTER) drive in a single
or dual drive configuration. This is the factory default setting.
SP Jumper - Slave Present
-------------------------
Used only when the second (SLAVE) drive in a two drive configuration
does not support DASP.
DASP
----
(Drive active / drive 1 present) is a CAM (Common Access Method)
defined signal that indicates the presence of a second drive, DASP is
used during power on initialization and after a reset. Prior to this
definition, products were introduced which did not utilize this
method to detect the presence of a second drive. The SP jumper is
used on the MASTER drive, with the DS jumper, when the second drive
does not support DASP.
CS Jumper - Cable Select
------------------------
Only used in systems that support the cable select feature. Cable
Select allows for each IDE disk drive to be jumped the same and the
position on the cable determines the ID. This requires a special
cable and both drives on the interface would have to support this
feature.
PK Jumper - Park (Spare)
------------------------
This jumper does not enable any feature. It is used, instead, to
provide a spare location to any jumper removed from the drive
during a configuration change.

QUANTUM ATA TIPS
Comparing the Fast ATA and Enhanced IDE Disk Drive Interfaces
-------------------------------------------------------------
Why are Fast ATA and Fast ATA-2 Important?
Faster data transfer rates are important because a computer is
only as fast as its slowest component. Today's 486, Pentium, and
PowerPC-based computers offer processor speeds many times faster
than only two years ago. Bus speeds have also increased with the
inclusion of 32-bit VL and PCI local buses, which have a maximum
data transfer rate of 132 MB/second.
Faster buses mean that data can be transferred from the storage
device to the host at greater speeds. Fast ATA and Fast ATA-2 allow
disk drives to store and access this data faster, thus enhancing the
other high-speed components in the system and removing the
bottleneck associated with older ATA/IDE drives. In short, Fast
ATA helps bring very high performance to desktop PC systems.
In addition, when compared to SCSI, Fast ATA is the least expensive
way to achieve faster disk drive data transfer rates and higher
system performance. The implementation of Fast ATA through system
BIOS provides performance without incremental hardware co sts.
Older systems can support Fast ATA using an inexpensive host
adapter.
Fast ATA and Fast ATA-2 are easy to implement in either VL or PCI
local bus systems. The hardware connection can be made using a
standard 40-pin ATA ribbon cable from the drive to the host
adapter. Direct connection to the motherboard further eases
integration when provided by the motherboard supplier.
Once connected, the high data transfer capabilities of Fast ATA can
be enabled through the data transfer options found in most CMOS BIOS
setup tables. Newer versions of BIOS provide automatic configuration
for Fast ATA drives.
Fast ATA can improve efficiency by allowing more work to be
completed in less time because the computer moves data faster.
Graphic, multimedia, and audio/visual software users will benefit
most because the speed of those applications, which work with large
blocks of data, are transfer-rate dependent.
The Fast ATA and Enhanced IDE interfaces both use the local bus to
speed data transfer rates. Enhanced IDE also uses the same PIO modes
as Fast ATA, although a data transfer rate equal to the PIO mode 4
rate has not been announced for Enhanced IDE. The major differences
between Fast ATA and Enhanced IDE are that the latter includes
three distinct features in addition to fast data transfer rates.
The additional features of Enhanced IDE are as follows:
High-capacity addressing of ATA hard drives over 528 MB -
a BIOS and device driver function.
Dual ATA host adapters supporting up to four hard disk drives per
computer system - a function of BIOS, operating system, and host
adapter, not the drive.
Support for non-hard disk drive peripherals such as CD-ROMs -
a function of BIOS and the operating system, not the drive
Each of these features supports improved functionality at a system
level, a positive development for the industry and end users.
However, support for all three features requires an extremely high
degree of integration and revisions to operating systems and hard-
ware, in addition to BIOS changes. Specific support is required not
only for the storage peripherals but also for host adapters, core
logic, the system bus, BIOS, and operating systems - virtually every
major block of PC architecture.
There is no central industry-supported standard that controls the
features of Enhanced IDE. With no standard, some products sold as
"Enhanced" may provide only one of the three features of Enhanced
IDE. For example, fast data transfer rate support is be coming
standard on mid-range and high-end local bus systems. This single
feature could satisfy the users immediate requirements without the
need for the other features of Enhanced IDE.
In the future, if the same system is upgraded to add the remaining
features of Enhanced IDE, users may be forced to purchase an Enhanced
IDE package that contains a feature already installed. This could
result in unnecessary costs, integration conflicts, and in-
compatibility with original factory implementations.
Fast ATA, on the other hand, represents only the fast data transfer
rates for ATA hard drives (support for PIO mode 3 or 4 and DMA mode
1 or 2). Fast ATA and Fast ATA-2 data transfer rates can be easily
achieved when the system BIOS and hard drive suppo rt the PIO and
DMA protocols.
BIOS that supports Fast ATA does not necessarily support high-
capacity addressing, dual host adapters or non-hard drive
peripherals. But these features are being introduced independently
by system manufacturers in order to compete in the PC marketplace.
All of Quantum's disk drives designed for PCs now support Fast ATA,
and new products with Fast ATA support will be introduced in early
1995. The drives are also fully backward compatible with older ATA/
IDE (non-Fast ATA) BIOS.
The Quantum drives support both the Extended CHS (Cylinder Head
Sector) and LBA (Logical Block Address) addressing methods in
overcoming the 528 MB DOS capacity barrier. Quantum drives can also
be used with dual host adapters.
Finally, there are no incompatibilities with Quantum hard drives
that would prevent computer systems from supporting non-hard drive
peripherals.
Quantum drives that support Fast ATA include the following families:
Quantum ProDrive LPS 170/210/340/420
Quantum ProDrive LPS 270/540
Quantum Maverick 270/540
Quantum Lightning 365/540/730
Quantum Daytona 127/170/256/341/514
Fast ATA and Fast ATA-2 are important technologies that can take
advantage of the performance provided by the latest high-speed
microprocessors and bus architectures. The high-speed interfaces
are based on industry standard specifications and are the least
expensive way to achieve faster disk drive data transfer rates.
Fast ATA is not a group of features that requires an extremely
high level of integration, and only represents the fast data transfer
rates for ATA hard drives (PIO mode 3 or 4 and DMA mode 1 or 2).
