Library /sys$common/syshlp/EFI$HELP.HLB  —  Examples  Device
    EFI$CP permits access to OpenVMS I64 bootable device structures.
    The example shows use of the LD logical disk capabilities and a
    backing file, though EFI$CP operations with a device are entirely
    similar once the LD device is connected.

    This section contains both an example and a detailed description.

1  –  Example 

 $ LD CREATE SYS$SCRATCH:LD.DAT/SIZE=2880
 $ LD CONNECT SYS$SCRATCH:LD.DAT LDA1:
 $ RUN SYS$SYSTEM:EFI$CP
 EFI$CP> initialize LDA1: EFI/NOLOG
 EFI$CP> mount LDA1: EFI/NOLOG
 EFI$CP> CREATE/DIRECTORY LDA1:\EFI\
 EFI$CP> CREATE/DIRECTORY LDA1:\EFI\VMS\
 EFI$CP> DISMOUNT LDA1:
 EFI$CP> EXIT

2  –  Description 

    The example creates, connects, initializes and creates two
    directories on an LD logical disk device. The LD device size
    shown was explicitly chosen to match a common FAT12 floppy disk
    block size, per FAT12 requirements.

    This particular FAT12 volume is presently too small for the
    current OpenVMS I64 bootstrap files IPB.EXE and VMS_LOADER.EFI.
