I have recently started to learn Linux, and Debian is the most likeable to me. I installed it on a notebook, and found that some firmware is missing (which is in line with what I read in the Installation Guide). I have the following questions:After the installation how can I print a list of all missing firmware, so that I can see how severe the problem is and which files I will need?I found that I can download firmware from https://cdimage.debian.org/cdimage/unofficial/non-free/firmware/stretch/current/. However, I still have the DVD attached to my notebook. Does it have any advantages if I use this manufacturer's DVD compared to downloading from cdimage.debian.org?Regarding the manufacturer's DVD, I found that the drivers take a lot of space (more GBs). How can I decide which directories and files are important for Linux (I would like to store them on an installer USB Stick)?I found one more link: https://cdimage.debian.org/cdimage/unofficial/non-free/cd-including-firmware/9.1.0+nonfree/amd64/iso-dvd/firmware-9.1.0-amd64-DVD-1.iso. Is it safe to assume that this is the same as the OfficialDVD1 + NonFreeFirmware? Is it a full package if I combine this one with OfficialDVD2 and OfficialDVD3?
