Kernel Error Messages

17: system software does not follow VCPI or DPMI specifications

Description Some memory-resident program has put your 386 or 486 CPU into virtual 8086 mode. This is done to provide special memory services to DOS programs, such as EMS simulation (EMS interface without EMS hardware) or high memory. In this mode, it is not possible to switch into protected mode unless the resident software follows a standard that DOS/16M supports (DPMI, VCPI, and XMS are the most common).

Action

Contact the vendor of your memory-management software.

22: cannot free memory

Description Memory was probably corrupted during execution of your program.

Action

Make more memory available and try again.

23:no memory for VCPI page table

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

Action

Make more memory available and try again.

24:VCPI page table address incorrect

Description There is an internal error.

Action

Contact technical support.

25:cannot initialize VCPI

Description

An incompatibility with other software was detected.

 

DOS/16M has detected that VCPI is present, but VCPI

 

returns an error when DOS/16M tries to initialize the interface.

Action

Find the other software that uses VCPI and disable it (stop its

 

execution).

28:memory error, avail loop

Description Memory was probably corrupted during execution of your program. Using an invalid or stale alias selector may cause this error. Incorrect manipulation of segment descriptors may also cause it.

Action

Rerun the program and/or restart your computer.
