Hi, when I boot from the current Vista build iso, it complains, that the BIOS is not ACPI compatible and quits. Will there be a way around that, soon?
No, unfortunately current version of Parallels Workstation will not be able to boot your Vista. Our development team is working hard to bring it's support in the upcoming versions of our product.
Apparently the TinyBIOS implementation in the VM doesn't support ACPI in a form that Vista can cope with.
