Ticket #16127 (new defect)
Setting up virtual LPT port to connect through to real LPT port stops DOS VM starting
|Reported by:||BrianGinUK||Owned by:|
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.
