Hi,
I've no idea what installer is trying to do with this port, or what
device it is probing.
We can maybe add a runtime switch to exit Qemu or not. What do you think
of '-vgabios-backdoor' which, if specified, does the exit ?
Otherwise, which solution do you propose?
Regards,
Hervé

The port 0x501 is (at least) used by SCO Xenix 2.3.4 installer.
For what? What device would normally be there?
I don't want to disable this by default. My regression suite depends on
this as an exit mechanism.
