This is for Single Density systems, the disk size and format in cpmtools / greaseweazle will need to be changed for DD models.

Create a file that's the right size (100K):

$ dd if=/dev/zero bs=1024 count=100 of=occ1sd.img

Create a CPM file system on the disk:

$ mkfs …

If you're feeling adventurous, combine the two hex files, and convert that into a binary:

$ cat cpsker.hex cpvosb.hex > kerm411.hex
$ hex2bin kerm411.hex …

Debian 11's version of the Secure Boot shim is a bugged version (< 15.7) that doesn't parse arguments properly [1] . fwupdmgr uses these arguments to boot an EFI application that then triggers a system firmware update.

To do my firmware update, I need to obtain a working / patched version of …
