Executing the Diagnostic Test

Toshiba MS-DOS is required to run the T6600C DIAGNOSTICS PROGRAM.
NOTE: You cannot run the diagnostics program on a computer that has loaded an
expanded memory manager such as EMM386 or Quarterdeck's QEMM into memory.
If you try to run diagnostics with either of these programs loaded, the following
message will display on the screen:
Cannot execute in a virtual 8086 mode .
There are two ways to run the diagnostics program: 1) by booting from Drive A, or 2) by
modifying the CONFIG.SYS file.
Boot from Drive A
1. Insert a Toshiba operating system diskette into the floppy disk drive (FDD).
2. Turn on the computer, then proceed to the "Running the Diagnostics Program"
section.
Modify the CONFIG.SYS File
1. Turn on the computer and allow it to boot.
2. Deactivate the line in the CONFIG.SYS file that loads the device driver for the
expanded memory manager by using the DOS batch command "REM." You may
also rename the CONFIG.SYS file to keep it from executing upon bootup.
3. Reboot the computer, then proceed to the "Running the Diagnostics Program"
section.
Running the Diagnostics Program
1. Insert the T6600C Diagnostics disk in the computer's internal floppy disk drive.
2. At the system prompt, change to Drive A (if necessary), type TESTCE66, and
press Enter .
