I suspected this was because int19 assumes a stack is set up, then reloads dos. So if the dos stack is the one being used, a crash occures. I ended up using a long jump to FFFF:0. - John N.

The 1234 forces a warm boot, otherwise you will get a cold boot unless you have done a ctrl-alt-del this session. -- ----- Glenn Connery, Bell Northern Research, Mountain View, CA {hplabs,amdahl,3comvax}!bnrmtv!connery
