Identical to the -s option except the device is instructed to use legacy
ISA addresses if possible.
Currently this only has an effect with the

device emulation.
This option will be deprecated in a future version.

Allow devices behind the LPC PCI-ISA bridge to be configured.
The only supported devices are the TTY-class devices,
