Lab Session 2: Reboot Virtual DOS Machine

When running DOS 3.3, 4.0, etc., if an INT 19h is called, the result is a reboot of the entire system. The objective of this lab is to show that the execution of an INT 19h in an OS/2 VDM is handled by the Virtual DOS Machine Manager (VDMM). What happens in OS/2 Version 2.0 when a program running in a VDM issues an INT 19h?
