Choice of Professionals

#1-TuffTEST-Pro is the overwhelming choice of most of the world's largest service and support organizations because they need a diagnostic tool that really finds hardware problems. This is significant because they have made their decision to use #1-TuffTEST-Pro after thorough comparative testing in controlled laboratory environments using known bad parts from their repair depot operations.

#1-TuffTEST-Pro customers include service leaders like AT&T Corp, NCR Corp, Unisys Corp, Xerox Corp, Getronics, Eastman Kodak, Honeywell IAC, Fujitsu-ICL, GTE Corp, etc.

The "Stand-Alone" Advantage

#1-TuffTEST-Pro is a "Stand-Alone" diagnostic program that has its own proprietary self-booting operating system. Simply turn the target PC off, insert the #1-TuffTEST-ProProgram CD-ROM into the CD-ROM Drive or the Program Diskette into Drive A, turn the target PC on, and #1-TuffTEST-Pro will boot and take complete control of the target PC

This "Stand-Alone" advantage allows #1-TuffTEST-Pro to operate directly on the PC's hardware without interference from the target system's native operating system. Thusprecise and highly reliable test results are consistently achieved.

In contrast, most other utility and diagnostic software products operate as an application program "under" the native operating system (DOS/Windows/etc.). Some even have to be installed on the fixed disk before you can use them. While this approach is effective for software and hardware "configuration" issues, attempting to diagnose "hardware malfunctions" through all the various layers of operating system and application software dramatically affects the quality and reliability of the tests.

IMPORTANT NOTE: When you create the self-booting media, if you look at the media you created via Windows (or any other operating system viewer) it will appear that the media is blank (no files will be visible). The ONLY way to know that you have created the self-booting media correctly is to boot from that media via a power-on start. Of course, the target system's BIOS boot sequence must be set to boot from that device first, else it will probably revert to the operating system's normal boot sequence of the designated hard drive.

High-Precision Tool

"#1-PC Diagnostics Company has the product to beat in this category. No other product can beat #1-TuffTEST-Pro in all the different tests.... For all-around, full-system diagnostics, this is the best on the market...." Service News Magazine

#1-TuffTEST-Pro is the high-precision diagnostic software "tool preferred by service and support professionals because:

#1-TuffTEST-Pro uses its own proprietary operating system and is self-loading. This allows it to:

#1-TuffTEST-Pro is written in assembly language, thus it:

#1-TuffTEST-Pro utilizes its own custom device drivers so that diagnostic routines interact directly with the PC's hardware. This ensures precise and reliable test results. Conversely, most operating system-dependent diagnostics must rely on the use of hardware drivers on the target system to exercise much of the hardware.

#1-TuffTEST-Pro bypasses standard ROM BIOS routines when they fail to provide an exact picture of the hardware. For example, most IDE fixed disk drives go into "translation mode" to bypass limitations in earlier hardware/software design. This translation mode masks the true information from the ROM BIOS. For accuracy, #1-TuffTEST-Pro accesses information directly from the controller and fixed disk drive. If this technique is not used, unpredictable/unreliable results can occur.

Thorough and Very Reliable Tests

#1-TuffTEST-Pro Program CD-ROM or Program Diskette contains multiple diagnostic programs in compressed format. Each program is custom written for a specific microprocessor/bus combination. As #1-TuffTEST-Pro loads, the microprocessor/bus combination of the target system is analyzed, and only the appropriate diagnostic program for that system is expanded and loaded into main memory.

Over 200 of the most rigorous tests and functions are then available for testing Main Memory, Extended Memory, Expanded Memory, Fixed Disk Drives (EIDE, IDE, SATA, SCSI, ESDI, ST506/412), Diskette Drives, Video Displays and Adapters, Serial and Parallel Interfaces, and Keyboards. Extensive error code information is generated and logged. The Error Log can be viewed or printed.

Error codes are defined in the User Handbook which is available in the Licensed User Area. The comprehensive User Handbook is in ".html" format, is over 75 pages long and can be viewed or printed in you browser or can be downloaded as a separate file for viewing or printing at a later time.

Tests and Functions

A brief overview of #1-TuffTEST-Pro's tests and functions follows. All tests can be run in single pass or continuous mode.

Note: The availability of individual tests is dependent upon the type of PC being tested.

Note: Four asterisks (****) after a test or function below indicates that it is unique to #1-TuffTEST-Pro and is not available in #1-TuffTEST.

Configuration Function

Certification Tests (Quick System Check)

Parallel Port Tests (LPT1, LPT2 & LPT3)

Serial Port Tests (COM 1, COM2, COM3, COM4 & up to 64 user-defined port addresses)

Diskette Drive Tests (drives A & B)

Fixed Disk Tests (drives 0, 1, 2 & 3) - Up to 2000 Gigabytes!

Main Memory Test

Note: when any of the Main Memory Tests are run, #1-TuffTEST-Pro can be relocated on each pass (from the lower portion of main memory to the upper portion of main memory and then back again). This insures that ALL of main memory is rigorously tested. Thisunequaled ability to test the lower portion of main memory (that is normally occupied by the operating system and operating system dependent programs) is vitally important because this is the most used portion of memory and, therefore, the most likely area to fail.

Extended Memory Tests - Up to 3.5 Gigabytes!

Keyboard Tests ****

Video Alignment Aids

Video Adapter Tests

Error Log Function ****

#1-TuffTEST-Pro supports desktop PCs that use Intel Pentium 4, Pentium III, Pentium II, Pentium Pro, Pentium, i486, 80386, 80286****, 8088****, 8086****, and compatible AMD and Cyrix processors with Industry Standard Architecture (ISA), Enhanced Industry Standard Architecture (EISA), VESA Local Bus (VLB), and Peripheral Component Inter-connect (PCI) bus configurations.

Note: four asterisks (****) after a test or function above indicates it is unique to #1-TuffTEST-Pro and is not available in #1-TuffTEST.

#1-TuffTEST-Pro will test all speeds, sizes and types of memory including RDRAM and DDR SDRAM.

TEST Plugs

TEST Plugs are used with the "external" parallel port and serial port tests. The specific tests are noted in Tests & Functions.

Complete TEST Plug pinouts are provided in the User Handbook for the 25-pin parallel, the 9-pin serial & the 25-pin serial TEST Plug.

What Doesn't #1-TuffTEST-Pro Do?

Now for the next logical question, "what doesn't #1-TuffTEST-Pro do"?

As stated earlier, #1-TuffTEST-Pro, with its own boot-loader and operating system, is a highly specialized diagnostic software "tool" that provides superior "hardware" testing because the target system's native operating system is never used or called into memory.

Thus, #1-TuffTEST-Pro can directly test major system components such as memory, fixed disk drives, diskette drives, serial & parallel ports, video, keyboard, etc. False positives and false negatives that can be induced by the system's native operating system are eliminated.

However, since the PC's native operating system is not available to #1-TuffTEST-Pro, it cannot use the operating system's functions or interact with the various devices that, due to their proprietary design, are not supported by the PC's BIOS. Examples include pointing devices, CD-ROM drives, sound cards, network cards, etc. These devices require the availability of their own special native operating system-based software drivers and only a utility that runs under the target system's native operating system can see and interact with these drivers.

Since numerous operating system-based diagnostic utilities have always been available to see, exercise and resolve conflicts with these devices, #1-TuffTEST-Pro has remained specialized in doing what it does best - directly and rigorously test the PC's basic hardware.

Our customers recognize this and use #1-TuffTEST-Pro in conjunction with, not instead of, operating system dependent products such as #1-TuffTEST for Windows Norton UtilitiesPC-DoctorCheckIt Pro, etc.  They use #1-TuffTEST-Pro to reliably test the system's basic "hardware" and DOS/Windows-based utility products for help with configuration issues and conflicts.

Ease of Use

#1-TuffTEST-Pro is extremely easy to learn because of its user-friendly, menu-driven structure. Service and support people, regardless of their experience level, can quickly zero in on the problem and repair or replace only the defective system component (instead of replacing good parts in a blind attempt to solve the problem by random parts swapping).

Technical Support

#1-TuffTEST-Pro comes with technical support during normal business hours via e-mail, fax, or mail.

Upgrade Information for New Version 3.53

Once you license #1-TuffTEST-Pro it can be upgraded for life. For your convenience, upgrades are always totally backward compatible so you never have to worry about using your old Program CD-ROMs or Program Diskettes with your new Program CD-ROMs or Program Diskettes.

A Welcome Addition To Your Tool Bag

In conclusion, a professional support/service person's tool bag is always full of "specialized" tools because they do a much better job than "multi-purpose" tools. For this same reason, no single diagnostic "software" tool is appropriate for all PC troubleshooting situations. That is why you need more than one diagnostic software "tool" in you tool bag.

Due to the lack of industry standards and the overwhelming number of different PC hardware manufacturers and configurations, no PC diagnostic software product will find ALL hardware problems. But over time#1-TuffTEST-Pro will find many more "hardware" problems than operating system dependent products.

To quote Service News, "....#1-TuffTEST-Pro is the best diagnostic product of its type,"....why not try it for yourself ?
