UATA100.EXE version 3.06 (p/n 22800061-010)
Utility to set default maximum Ultra ATA Support
_____________________________________________________________________
Copyright (c) 1999-2003 by Seagate Technology LLC. All rights
reserved.
The new Ultra ATA/100 interface extends the speed up to 100
Mbytes/second burst transfer rates using Ultra DMA mode 5. The Ultra
ATA/66 interface doubles the speed of data transfers on the ATA (IDE)
bus, providing up to 66.6 Mbytes/second transfer rates using Ultra DMA
mode 4.
Many Seagate disc drives can be configured to support a default
maximum transfer rate. This can range from transfer rates between 16
and 100 Mbytes per second, depending on your drive model. Using this
software utility, you can set the default transfer rate to the best
capability of your system.

Requirements
------------
There are four requirements for attaining Ultra ATA33, Ultra ATA/66 or
Ultra ATA/100 - collectively referred to as Ultra ATA/33/66/100:
* The drive must support the specific feature of Ultra
ATA/100/66/33.
* The motherboard and system BIOS (or an add-in controller) must
support the specific feature of Ultra ATA/100/66/33. BIOS and
system settings may call these UDMA or Ultra DMA modes 5, 4 and
2.
* The operating system must support Direct Memory Access (DMA);
Microsoft Windows Me, 98 and 95b support Ultra ATA/100/66 and
lower. Windows 95a supports up to Ultra ATA/33.
* The cable must be 40-pin 80-conductor cable to support Ultra
ATA/100/66. A standard 40-pin ATA inferface cable for
Ultra ATA/33 (Ultra DMA modes 2 or 3). The length should not
exceed 18 inches.
If all the above requirements are met, the drive default setting can
be re-configured to support its highest Ultra ATA mode. The default
setting may be set slower than the maximum system capability. However,
the drive default setting should never be set faster than the maximum
system and cable capabilities.

=====================================================================
Usage
-----
This utility may not be executed while Microsoft Windows is active. To
use this utility, create a bootable MS-DOS diskette that contains a
copy of this utility and boot from the diskette.
This program will run as either a menu-based program or by command
line options.
From a command prompt, type
uata100
and press ENTER.
In the menu-based mode, use the up and down arrow keys to select the
controller and then drive to re-configure. The utility will only allow
selection of supported devices (if only one supported device is
present, the arrow keys will appear to have no effect).
Press the ENTER key to display a highlighted list of the drive's
available Ultra DMA modes. Do not set the new maximum mode higher
than the capability of your system and cable. See the Requirements
section above for complete details.
After the utility has completed, reboot the system.
In the command line mode:
UATA100 [option]
where [option] can be one of the following
-m <#> Set the maximum Ultra DMA mode to # for each
configurable device found.
-d Set the maximum Ultra DMA mode to the device maximum for
each configurable device found.
or if no command line options are given, user interactive mode will
start.
=====================================================================
Background
----------
Ultra ATA/100/66-capable devices from Seagate and others are currently
shipping; however, few systems currently support the highest protocol.
Furthermore, some BIOSs do not operate correctly with drives set to
run in Ultra ATA/100/66 modes.
For example, some BIOSs check for Ultra ATA (also called Ultra DMA)
support and subsequently set the mode to the maximum speed supported
by the drive, regardless of the system support. These systems may only
provide support up to Ultra ATA/33, but they set the drive to operate
in Ultra ATA/100 or ATA/66 mode, causing the system and drive to
attempt to communicate at different speeds.
Current Seagate Technology Ultra ATA/66-capable drives are configured
to support Ultra ATA/33 when shipped. This shipping configuration
ensures maximum compatibility with systems available today. If the
requirements noted above are met, then the drive may be re-configured
to support Ultra ATA/100 or ATA/66 by running the UATA100.EXE utility.
This utility will also support resetting the configuration to support
the original Ultra ATA/33 configuration.

What is Ultra ATA/66?
---------------------
Ultra ATA/100, also known as Ultra DMA mode 5, enhances existing Ultra
ATA/66 or Ultra ATA/33 technology by increasing both performance and
data integrity. This new high-speed interface triples the Ultra ATA/33
burst data transfer rate to 100 Mbytes/sec. The result is maximum disc
performance using the current PCI local bus environment.
How does Ultra ATA/100/66 attain faster transfer rates?
---------------------------------------------------
Ultra ATA/100/66 removes bottlenecks associated with data transfers,
especially during sequential operations. Ultra ATA/100/66 requires a
special 40-pin, 80-conductor cable that reduces noise bleed-over and
improves signal integrity by providing 40 additional ground lines
between each of the standard 40-pin ATA (IDE) signal lines and ground
lines.
Who is developing Ultra ATA/100/66 drives?
--------------------------------------
Ultra ATA/100/66 is endorsed by all leading hard drive manufacturers
including Seagate, Fujitsu, IBM, Maxtor, Quantum, Toshiba, Western-
Digital and others. The Ultra ATA/100/66 protocol is also endorsed by
Intel with full industry support expected in 1999.
Is Ultra ATA/100 backward compatible with my current Ultra ATA/33
system?
----------------------------------------------------------------
Yes. Ultra ATA/100 is backward compatible with all Ultra ATA/33
systems, but it w1ill be limited in its transfer mode to the Ultra
ATA/33 (Ultra DMA Mode 2 - 33.3 Mbytes/sec) or PIO Mode 4 (16.6
Mbytes/sec). Ultra ATA/100/66 hard drives are 100 percent backward
compatible with both Ultra ATA/33 and DMA and with existing ATA (IDE)
hard drives, CD-ROM drives, and host systems. The Ultra ATA/100/66
protocol and commands are designed to be compatible with existing ATA
devices and systems. Although a new 40-pin, 80-conductor cable is
required for Ultra ATA/66, the chipset pin count remains the same at
40. Hard drives that support Ultra ATA/100 also support Ultra
ATA/66/33 and legacy ATA (IDE) specifications.
What is required to run in Ultra ATA/100 Mode?
---------------------------------------------
There are basically four requirements:
* An Ultra ATA/100-capable system board and BIOS.
* An Ultra ATA/100-capable 80-conductor cable.
* An operating system capable of DMA transfers.
(WinMe, Win98 and Win95 (OSR2) are capable.)
* An Ultra ATA/100 capable device. (Seagate drives require an
activation utility for each device.)
Ultra ATA/100/66 technology is defined such that the PC and the hard
drive can both detect the presence of the required 80-conductor cable.
The system board must have a special capacitor on pin 34 to detect the
cable. The cable must have a notch cut in line 34 to correctly detect
an Ultra ATA/100/66 device.
Where can I get the utility to activate Ultra ATA/66 on my drive?
-----------------------------------------------------------------
Eventually, all Ultra ATA/100/66 drives will be shipped with the
utility either on diskette or CD-ROM. In the interim, the utility
(UATA100.EXE) can be downloaded from
ftp://ftp.seagate.com/techsuppt/seagate_utils/uata100d.exe. The
version available on the web is a self-extracting zip file and must be
unzipped and placed on a bootable diskette.
Why is there a blue, black and a gray Connector on my Ultra ATA/66
cable?
------------------------------------------------------------------
The 40-pin, 80-conductor cables will support the Cable Detect feature.
The blue (end) connector should be connected to the system board. The
black (end) connector is known as the master position. The gray
(middle) connector can be used for a slave device as needed. Although
an Ultra ATA/100/66 device should work fine in either the black or the
gray connector, if your are having difficulty, consider
troubleshooting with the drive in the black connector.
Can I mix Ultra ATA/33 and Ultra ATA/66 drives on the same cable?
-----------------------------------------------------------------
Yes, a legacy ATA (IDE) specification drive can coexist with an Ultra
ATA/66 drive. However, for the Ultra ATA/66 device to attain Ultra
DMA 4 mode, an Ultra ATA/66-capable cable is required.
What operating systems support Ultra ATA/66?
--------------------------------------------
Primarily because the operating system is not the controlling factor,
most operating systems, including all current Windows versions
(Windows XP, 2000, Me, 98, and 95 (OSR2)), support Ultra ATA/66. Ultra
ATA data transfer rate is determined by your hard drive, your
controller, and the BIOS. The only requirement on the operating system
is to be able to support DMA transfers.
Do I need a special Ultra ATA/100/66 device driver?
-----------------------------------------------
Not necessarily. Because the operating system (WinMe/98/95) handles
Ultra ATA and Ultra ATA/100/66 the same as DMA, there should be no
special device drivers. However, as with Ultra ATA (IDE), not all
system boards and BIOSs will correctly interface with the operating
system. In these cases, a special device driver or patch will have to
be provided by the system board manufacturer to make the system
capable of attaining Ultra ATA/100/66.
What are some common troubleshooting steps?
-------------------------------------------
1. Make sure the cable is Ultra ATA/100/66 capable. An Ultra
ATA/66-capable cable is a 40-pin, 80-conductor cable with a
black connector on one end, a blue connector on the other end,
and a gray connector in the middle. In addition, line 34 on the
cable should be notched or cut (this may be hard to see with the
human eye).
2. Make sure the system board is capable of Ultra ATA/100/66. An
Ultra ATA/66-capable system board has a detect circuit with a
capacitor for detecting line 34 missing on the cable. If there
is no capacitor, the system can wrongly detect the presence of an
Ultra ATA/100/66 cable and therefore try to configure the device
for a higher transfer rate.
3. Some system boards may not successfully handle Ultra ATA/66 on
both ATA (IDE) channels. If you have difficulty, consider
troubleshooting with the device in the Primary Master position.
4. Contact the system board manufacturer for the latest BIOS
upgrade and any Ultra ATA/66 special device drivers or patches.
5. Make sure the operating system is DMA capable and that the DMA
mode is activated. (For Windows 95/98, check Device Manager |
Drive Settings tab for a check box.)
6. Make sure the drive is Ultra ATA/100/66 capable and has been
configured to run at Ultra ATA/66 transfer rates. (Seagate
drives require an ultra ATA activation utility.)
