Executing the DiagnosticTest
Toshiba MS-DOS is required to run the T4700CS/T4700CT/T4800CT DIAGNOSTICS
PROGRAM.
NOTE: Diagnostics cannot be run with expanded memory managers such as
EMM386 or Quarterdeck QEMM in memory. Attempting to run diagnostics with either
program loaded will cause the following message to display:
Cannot execute in a virtual 8086 mode.
There are two ways to run diagnostics: 1) Booting from Drive A or 2) modifying the
CONFIG.SYS file.
Boot from Drive A
1.
Insert a Toshiba operating system diskette into the 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 CONFIG.SYS file line that loads the device driver for the expanded
memory manager by using DOS batch command "REM." The CONFIG.SYS file
may also be re-named to keep it from executing upon bootup.
3.
Re-boot the computer, then proceed to the "Running the Diagnostics Program"
section.
Running the Diagnostics Program
1.
Insert the Diagnostics disk in the internal FDD.
2.
At the system prompt, change to Drive A (if necessary), type TESTCE47 or
TESTCE48, and press Enter .
