Kernel Error Messages

A.2 Kernel Error Messages

This section describes error messages from the DOS/16M kernel embedded in the TMS470R1x code generation tools. Kernel error messages can occur because of severe resource shortages, corruption of the executable file, cor- ruption of memory, operating system incompatibilities, or internal errors. All of these messages are quite rare.

DOS/16M protected mode available only with 386 or 486

Description

DOS4G did not detect the presence of a 386-, 486-, or Pen-

 

tium-based processor.

Action

If you are running the tools on a 386 (or later) PC, rerun the

 

program. If you are running the tools on a 286 PC, reinstall

 

and run the tools on a 386 PC or later.

0: involuntary switch to real mode

Description

The computer was in protected mode but switched to real

 

mode without going through DOS/16M. This error most often

 

occurs because of an unrecoverable stack segment

 

exception (stack overflow) but can also occur if the global

 

descriptor table or interrupt descriptor table is corrupted.

Action

Restart your computer. If the problem persists, contact tech-

 

nical support.

2:not a DOS/16M executable <filename>

Description DOS4G.EXE or a bound DOS/4G application has probably been corrupted in some way.

Action

Recopy the file from the source media.

6:not enough memory to load program

Description There is not enough memory to load DOS/4G.

Action

Make more memory available and try again.

8:cannot open file <filename>

Description

The DOS/16M loader cannot load DOS/4G, probably

 

because DOS has run out of file units.

Action

Set a larger FILES= entry in the CONFIG.SYS file, reboot,

 

and try again.
