Yes it is meaningful.
Further study led to this helpful page on the topic. It discussed the instructions available here, which ultimately led to this repository of EFI shell programs. For my purposes** I used this file from the repository to populate the USB drive prepared as follows:
- Format USB stick with FAT32 partition (let's say it mounts to
X: in windows or
/usb-stick in Linux)
- Download EFI shell script from links above, moving it to the newly created
- It may be necessary to rename the file as per the linked instructions, in my case with a 64 bit architecture I needed to name the file
With this arrangement, of files on the USB stick, it is now bootable using a UEFI compatible motherboard firmware. (Adam Williamson implores us to not call it a UEFI compatible BIOS!). Put the stick in an enabled USB port in the target computer, do whatever is necessary to boot from the USB stick in UEFI mode, and it will open an EFI shell. Continuing through Bryan Vyhmeister's post allowed me to successfully use the EFI shell to complete the task I had at hand.
** I needed the 'full' version as it gave access to the
mount function required to get access to the files and executables on the USB drive.
