SYMPTOMS

If you have an 84-key keyboard with the Toshiba 5100, using the SHIFT key with the UP or DOWN ARROW keys may not work properly with the MS-DOS version 5.x and versions 6.0 and later utilities.

CAUSE

In MS-DOS Shell, Qbasic, or Edit, pressing the SHIFT+UP/DOWN ARROW key combinations for text or file selection does not work correctly with an incorrect CMOS setup.

The Toshiba 5100 CMOS setup contains options for an 84 or 101-key keyboard. The SHIFT+UP/DOWN ARROW key combinations do not operate properly if the setup is configured for an 84-key keyboard.

The Toshiba CMOS setup option for 84-key keyboard selection disables the 17 page editing keys. This prevents the UP/DOWN ARROW keys from working in conjunction with the SHIFT key.

RESOLUTION

To correct the problem, change the system CMOS setup from an 84-key keyboard to a 101-key keyboard, as follows:
  1. Insert the Toshiba Setup disk in drive A.
  2. At the A prompt, type TEST3 and press ENTER.
  3. Enter 0 (zero) for the Setup option.
  4. Select the Keyboard option.
  5. Change the 84-key keyboard to the 101-key keyboard.
  6. Press F10 to save your changes and exit Setup.
