We have a system that is based on windows NT4, because of hardware limitation we are moving to linux on new hardware + virtual windows nt4 (virtualbox).
but the virtual one is not working as it have to,
Also i tried linux dd to copy real nt harddrive to virtual hard drive,but the system is not working as it have to .
more about the situation:
our external hardware is a n-port to map external com ports over tcp/ip. the virtual pc boots with no problem,windows starts with no problem,application starts with no problem,communication just starts with no problem,but disconnect!with some timeout like errors.
note: a fresh install of NT and softwares on VirtualBox also have the same problem.
