| **VT-d** | 也叫 `Intel® Virtualization Technology for Directed I/O (VT-d)` |

!!! note "**CFG Lock**"

1. MSR 0xE2 写保护
2. 建议关闭，提高黑苹果完美度，很多笔记本没有这些选项，可能需要自己手动去解锁隐藏 BIOS 选项
3. 如果不关闭的话，config.plist 配置里面设置 `AppleXcpmCfgLock` 选项为 `YES` 也是 OK 的 （但是完美度不如关闭 CFG Lock）

!!! example "VT-d"
!!! example "**VT-d**"

1. I/O 的虚拟化技术，和 **VT-x** 很容易混淆
2. 建议关闭，一般搞 PVE 硬件直通才需要开启，正常普通人是用不到硬件直通技术的
3. 如果不关闭的话，config.plist 配置里面设置 `DisableIoMapper` 选项为` YES` 也是 OK 的
