AT Jumper Requirements
For notebook computers with two hard drives, a master/slave
relationship must be established. If only one hard drive is installed
on the ATA bus, it must be configured as the master drive.

If two hard drives are installed on the ATA bus, one must be
configured as the master and the other as a slave. The drive position
on the cable (first or last physical device on the cable, for
example) has no effect on the master/slave relationship. The jumper
settings and the Cable Select option determine the master/slave

Cable Selection
Quantum 2.5-inch AT drives can be configured such that its status as
a master drive or slave drive can be determined by the cabling from
the host system.

This is extremely helpful when the drive is used as a removable
subsystem where it can be either master drive or a slave drive
depending upon the cable to which is connected.

When a drive is configured for cable selection, it is master drive if
Pin 28 is grounded and a slave if Pin 28 is not grounded.

For systems that do not use Pin 28 for another purpose (e.g., Spindle
Synchronization), the host system can tie Pin 28 to ground. Then the
cable connecting the host to the master has Pin 28 enabled (i.e., a
circuit exists), while the cable connecting the slave to either the
host or the master has the Pin 28 line servered.

Systems that use Pin 28 can use the cable selection method by
performing the following:

   1. Connect the system cable in the following order
      host <--> slave <--> master.

   2. Cut the Pin 28 line between the slave and the master. This
      allow Pin 28 to operate normally (an open - served connection)
      between the host and the slave.

   3. Tie Pin 28 (within the master drive header) to a nearby ground
      (Pin 30, for example).

This process will allow the master drive to have Pin 28 grounded
while allowing the Pin 28 to be open between the host and slave

Notes on Installation

Dimensions and Mounting
The drive can be mounted in any orientation. Maximum screw length is
3mm with three minimum full threads. The maximum mounting torque for
these screws is 40 inch-ounces. Clearance from the drive to any
surface (other than the mounting surface) should be 0.05" minimum.

For optimum drive performance, the system mounting method should not
result in any distortion or twisting of the drive's base casting.
For example, if the drive is attaches (via its bottom mounting holes)
to a stiff mounting surface that does not meet Quantum Europa AT
drives flatness requirements of 0.01", the performance may be

Quantum Europa AT hard disk drives can operate without a cooling
fan, provided the ambient air temperature des not exceed 55*C
(131*F). Any user-designed cabinet must provide adequate air
circulation to prevent the maximum temperature from being exceeded.

Cable Connector
Europa AT hard disk drives have a single 2 x 22 connector (on
2mm centers) for both power and data. The connector also includes
four pins which are reserved for factory test points - these pins
must be allow to float.

The recommended system mating connector is a 3M Series 150 or
equivalent. The maximum cable length is 18 inches. To assure that the
system cable connector is installed with the proper orientation, plug
the Pin 20 hole on the system connector.

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

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

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).
