∙The program called T.EXE is a noninteractive test executable used to run test program modules from DOS batch files.
∙The README.TXT file for diagnostics tells how to install the program.
CAUTION
Read help information for a test before running it: the diagnostic package contains many optional tests that should be used only by a user with advanced technical knowledge. Inadvertent actions could be damaging, such as running a hard drive write test on a hard disk. All tests that require external hardware, user interaction, or are destructive, are disabled in the default configurations. Before using such a test, make sure you read and understand the help information for that test.
