Quote: "but on real system don't work and hang PC"
I downloaded comodo.iso (nice freeware by the way - haven't seen this one before )
Did the same as you and failed when testing from qemu - but worked from a 'real boot' using USB stick (but no mouse support ) Note: I have a pretty brand new motherboard, so I tested from my 3 year old computer and it worked to 100% from that one
I'm confident this is a 'hardware' problem and not a 'software' problem
Seems this comodo software has limits to its support regarding hardware - but still a nice piece of software -------------------
