16127,Setting up virtual LPT port to connect through to real LPT port stops DOS VM starting,Brian Gregory,,"I run VirtualBox on a Windows 7 Ultimate 64 bit host.
I find that with VirtualBox 5.1.4, 5.1.6 and 5.1.8 and 5.1.9-111573 (with matching Extension Pack installed) my FreeDOS 1.1 VM will not start at all after issuing the following VBoxManage commands:
VBoxManage modifyvm ""FreeDOS 1.1"" --lptmode1 LPT1
VBoxManage modifyvm ""FreeDOS 1.1"" --lpt1 0x378 7
to create a virtual LPT port and connnect it through to my real LPT1 port (on a PCI card, at address I/O address C000)
I am reverting to VirtualBox 5.1.2 for now.
I am attaching the log files and configuration of the VM in a ZIP file.
The oldest log file ""VBox.log.3"" is one from when it last worked, the others are fails.
