Used to be you could disable Intel-VT in BIOS to prevent blue screening when running multiple hyper-visors. But now it throw fits when both are running at the same time. Hardware Virt Cannot be disabled for XP Mode, Microsoft made it pre-req. Is there fix to disable hardware virtualization from inside VMware, like trick it into thinking is disabled in the BIOS. Is version Workstation 6.5.2 and the VPC RC.
