Error: error.TNT:20074: (when opening DOS-based CAD program due to Pharlap.386).

Error:


error.TNT:20074: cannot use -REALBREAK under this version of DPMI

Cause:


This error mostly occurs when running MS-DOS-based CAD programs such as AutoCAD. The Pharlap.386 driver is not loaded in SYSTEM.INI. These types of programs will not run without this driver.

Solution:


Edit System.ini and add device=X:\PHARLAP.386
(where 'X:' is the path to the Pharlap.386 file).
