ScanCode This is the UEFI-defined Scan code portion of the EFI_INPUT_KEY struction. This value is directly associated with the preceding KeyData value and there may be 1 to 4 entries per the UEFI specification. When one instance of this parameter has a non-zero value, the paired UnicodeChar value will have a zero-based value.
UnicodeChar This is the Unicode value for the character associated with the preceding KeyData value. There may be 1 to 4 entries per the UEFI specification. When one instance of this parameter has a non-zero value, the paired ScanCode value will have a zero-based value.

The rm option can be used to delete a Boot#### or Driver#### environment variable, and finally, then mv option can be used to reorder the Boot#### and Driver#### environment variables. The add, rm, and mv options also update the BootOrder or DriverOrder environment variables as appropriate.

温馨提示
EFI (macOS Mojave 10.14.6),问题:黑苹果进入四叶草界面回车后一直黑屏,引导失败。修复方法:格式化一个U盘为FAT32,解压EFI.zip,拷贝目录EFI到U盘,开机按F2选择U盘启动,进入四叶草界面,启动macos系统,会跳转到硬盘引导的四叶草界面,回车,成功修复引导,进入黑苹果系统。
