Hi,
We don't provide firmware-included
versions of every media type, just netinst and DVD.
Perhaps you can give me the link with info how to make my own files
*.jigdo & *.template
For that, you'll need a full local mirror and use debian-cd.
How about adding the firmware files to an existing BD ISO by means of
xorriso ?
xorriso -indev debian-11.2.0-amd64-DLBD-1.iso \
-outdev my-firmware-11.2.0-amd64-DLBD-1.iso \
... add firmware files at suitable position in ISO tree ... \
-boot_image any replay \
... jigdo production options ...
or like in
https://wiki.debian.org/RepackBootableISO
(without removing the jigdo options, of course).
How difficult would it be to use such added firmware when the ISO is
booted ?
(I remember that, a few years ago, some Debian ISO had an appended
partition for storing firmware files, which were to be used when the ISO
was booted from a USB stick.)
I offer help with the xorriso part. But the Debian installer part would
need other experts.
Have a nice day :)
Thomas
