 TTW Diagnostics for DOS

TTW Diagnostics for DOS is a DOS-based diagnostics program. It is a component of #1-TuffTEST for Windows that helps you diagnose hardware problems on your PC. It bypasses the Windows operating system layers and performs tests down to the physical hardware level. The test results reflect your system's stability, reliability and compatibility.

Some Plug-an-Play (PNP) devices do not get initialized under DOS and will not be detected or tested. If possible, select Non-PNP Operating System in the system's BIOS Setup program.

When Hardware Diagnostics (MS-DOS) is selected from the #1-TuffTEST for Windows Tools menu, a message box will pop up as shown below:

Click on Yes to restart the computer in MS-DOS mode and use the current configuration in AUTOEXE.BAT and CONFIG.SYS, and then run TTW Diagnostics for DOS. The restart process is same as the option "Restart the computer in MS-DOS mode" in the Shut Down Windows message box. Certain tests will be skipped if memory managers, such as EMM386.EXE, are detected.

Click on No to restart the computer in MS-DOS mode and use the default configuration specified by TTW Diagnostics for DOS. This function will reboot the computer, remove all memory manager drivers, boot up from MS-DOS and then run TTW Diagnostics for DOS.

TTW Diagnostics for DOS can also be run in command-line mode without user interaction. This mode is mainly used for production line or burn-in testing.


So whenever you have doubts about your system's reliability, or whenever you buy, build or repair a PC, you can use #1-TuffTEST for Windows to perform a rigorous physical examination on your PC and understand its stability and capability. Distributed via download only.
