DOS/4G Error Messages

A.3 DOS/4G Error Messages

DOS/4G errors are more common than kernel errors when using DOS/4G or DOS/4GW with the TMS470R1x code generation tools. They are usually re- lated to an unknown path name, corrupt files, or memory problems. Memory problems can include inadequate memory, poor configuration, or corrupted memory.

1000 ºcan't hook interruptsº

Description A DPMI host has prevented DOS/4G from loading.

Action

Contact technical support.

1001 ºerror in interrupt chainº

Description A DOS/4G internal error was detected.

Action

Contact technical support.

1003 ºcan't lock extender kernel in memoryº

Description DOS/4G could not lock the kernel in physical memory, prob- ably because of a memory shortage.

Action

Free some memory for the DOS/4G application.

1005 ºnot enough memory for dispatcher dataº

Description There is not enough memory for DOS/4G to manage user- installed interrupt handlers properly.

Action

Free some memory for the DOS/4G application.

1007 ºcan't find file <program> to loadº

Description DOS/4G could not open the specified program. The file prob- ably does not exist. It is possible that DOS ran out of file han- dles or that a network or similar utility has prohibited read ac- cess to the program.

Action

Make sure that the filename was spelled correctly.

1008 ºcan't load executable format for file <filename> [<error code>]º

Description DOS/4G did not recognize the specified file as a valid execut- able file. DOS/4G can load linear executables (LE and LX) and EXPs (BW).

Action

Recopy the file from the source media.
