Independently verify checksum of BIOS update

@jonathon.hall

Downloaded coreboot_util.sh from Update PureBoot - Purism user documentation

The tutorial mentions the download of a .zip however the file downloaded is actually unpacked set of files including a ROM.

I am wanting to verify the hash but there is no checksum or further information from the utility. Had a look at the contents of the shell script, there are checksums but presume these are for the archive before they are unpacked.

I’m wanting to move my ROM to the USB but I can’t verify the file. Any guidance on this?

Model: Purism Librem Mini v2
PureBoot version: PureBoot_Release_18.1
