I'm running FreeDOS 1.1 under VirtualBox, and I was asked if my PM debugger 386SWAT works in that environment which it does.
Among other things, this debugger can trap INT 02h in PM so it may be invoked via NMI even when the machine appears to be locked up. To test this, I entered the following commands from the VirtualBox directory: vboxmanage startvm "FreeDOS 1.1" and after FreeDOS initialized: vboxmanage debugvm "FreeDOS 1.1" injectnmi which I thought should signal NMI in FreeDOS, however the NMI doesn't appear to be signalled. I tried booting FreeDOS with each of the first three default configurations as well as a new fifth one which loads 386SWAT as a RM debugger and no other drivers. In each case, when the NMI sent, nothing happened. Now I know it used to work way back when I ran DOS as my OS using a hardware breakout switch, so I'm puzzled. This might well be a VirtualBox problem, but I thought I'd ask here first. -- _______________________________________________________________ Bob Smith - [email protected] http://www.sudleyplace.com - http://www.nars2000.org ------------------------------------------------------------------------------ Keep Your Developer Skills Current with LearnDevNow!
