Nice rant but #libreboot is a godsend.

I actually have comfort in how my laptop's boot process works now, and I get to dodge garbage UEFI that every manufacturer seems to put in their laptops now. This is not a privacy concern for me, it's just the bugginess makes Linux and other operating systems a bit unusable.

I modified bbswitch so I could switch Optimus off/on using x86 IO in kernel space. Unfortunately it works 80-90% of the time, and this **really** should only be done in BIOS space. x86 seems to share the notion of Ring 0 with most of coreboot and the kernel, but think about the System Management Mode components (and the ME, if it were still active in this BIOS).

I don't know much about the coreboot codebase but there are stale but pending patches for Optimus support on certain Lenovo W series ThinkPads that seem to share the same Power Management IC. Patience...

American schools had machine shop electives. Offer them the same with computers' inner workings if they so wish.

#Microsoft s Einfluss ist viel größer, als "nur" #Windows, #Office & #Azure: Der Konzern hat über Jahre hinweg #Secure #Boot aus dem #UEFI-Standard zum eigenen Vorteil beeinflusst. Da UEFI das klassische #BIOS abgelöst hat, besitzen sie weitreichende Kontrolle über den Startprozess von #Betriebssystemen auf nahezu allen #Computer.

Auch selbst gebaute Systeme sind betroffen. Nur sehr wenige Geräte sind frei, wenn diese mit einer angepassten, freien #Firmware gestartet wird.

Das hat bereits massive negative Auswirkungen auf freie #Betriebssysteme wie #GNU/#Linux.

Auf Dauer könnte sich der #PC in ein geschlossenes, rein auf Konsum orientiertes System wandeln - wie wir es bereits unter #Smartphones erleben.

there is a patch i want to test, relating to thunderbolt functionality. i will also test this myself, but having another user present will help too.

this patch: https://review.coreboot.org/c/coreboot/+/88490

i will send you a rom to test

Since I've been on Mastodon I have:
• bought 2 used ThinkPads
• bought a kit to #libreboot said ThinkPads
• started a recurring donation to @signalapp
• started playing with #meshtastic devices

Amazing what no algorithms will do for privacy, security, and sustainability.

Funny, that #Libreboot in the #fastfetch output displayed as "CBET4000" — the same letters used for the word "Light" (свет) in Russian. So, I read this line as "LIGHT4000"
