3.2 Executing the Diagnostic Test
Toshiba MS-DOS is required to run the diagnostics program. To start the diagnostics program,
follow these steps:
1. Turn on the computer, and allow the computer to boot. Insert the ASP Diagnostics
diskette in the computer’s internal floppy disk drive.
2. At the system prompt, change to drive A and type TESTCE45 for T4500/T4500C or
TESTCE46 for T4600/T4600C, and press
Enter
.
NOTE: You cannot run the diagnostics program on a computer that has loaded an ex-
panded memory manager such as EMM386 or Quarterdeck’s QEMM into memory. If you
try to run diagnostics with EMM386 loaded, you will get the following message:
Cannot execute in a virtual 8086 mode.
To run the diagnostics program, you must:
❑
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).
❑
Reboot the computer.
❑
Insert the ASP Diagnostics diskette into the FDD and continue with Step 2 above.
When testing is complete, don’t forget to restore the CONFIG.SYS file to its original state.
