Add load command to load EFI driver. (Same function as GRUB2's efiload command and EFI Shell's load command)
Download: BOOTX64.zip (144.17 KB, download times: 54)
usage:
           load [-n] /path/to/driver.efi
Example:
           load /boot/ntfs_x64.efi
           Load NTFS driver, and then enter EFI Shell or refind to read files on NTFS.

           load -n /boot/CrScreenshotDxe.efi
           Load the screenshot driver, after loading, you can press Left Ctrl + Left Alt + F12 to take a screenshot. The picture format is png and saved in the root directory of the first FAT partition found.

           load /boot/EfiGuardDxe.efi
           Load the driver that cracks the Windows driver signature verification. (May not support newer Windows versions, such as 20H1)

NOTE from alacran: IMHO I prefer to use /EFI/grub folder (where menu.lst resides):

Example:

load /EFI/grub/ntfs_x64.efi
