Troubleshooting DOS Systems
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.
