Using the capital punishment symbol instead of the killed in action symbol suggests windows was executed after the war (likely by installing linux lol)
There are variations of the Skull and Crossbones here that have specific meaning?
On wikipedia, capital punishment is a skull and amd bones, killed in action is a christian cross
I have a motherboard in a state where it won’t boot unless you pull and reinsert the cmos battery. After this it will boot exactly once.
It will also boot without issue if you don’t have a cmos battery at all. This is obviously not ideal.
I wonder if these issues are related? I purchased the motherboard second hand in this state about a year ago. So it is far too early for this update, but it remains a mystery.
Have you tried putting in a new battery?
Wait… Microsoft is shit?!
But how many civilians cannibalized?

Does “Secure Boot” actually benefit the end user in any way what so ever? Genuine question
For you? No. For most people? Nope, not even close.
However, it mitigates certain threat vectors both on Windows and Linux, especially when paired with a TPM and disk encryption. Basically, you can no longer (terms and conditions apply) physically unscrew the storage and inject malware and then pop it back in. Nor can you just read data off the drive.
The threat vector is basically ”our employees keep leaving their laptops unattended in public”.
(Does LUKS with a password mitigate most of this? Yes. But normal people can’t be trusted with passwords and need the TPM to do it for them. And that basically requires SecureBoot to do properly.)
It prevents rootkit malware that loads before the OS and therefore is very difficult to detect. If enabled, it tells your machine to only load the OS if it’s signed by a trusted key and hasn’t been tampered with.
Well yes, assuming that:
- you trust the hardware manufacturer
- you can install your own keys (i.e. not locked by vendor)
- you secure your bios with a secure password
- you disable usb / network boot
With this you can make your laptop very tamper resistant. It will be basically impossible to tamper with the bootloader while the laptop is off. (e.g install keylogger to get disk-encryption password).
What they can do, is wipe the bios, which will remove your custom keys and will not boot your computer with secure boot enabled.
Something like a supply-side attack is still possible however. (e.g. tricking you into installing a malicious bootloader while the PC is booted)
Always use security in multiple layers, and to think about what you are securing yourself from.
Yes, as long as you get the option to disable it. And use custom keys.
It’s uh, more secure.
I enrolled custom keys and bricked my motherboard 🙃
Same. Should’ve listened to securebootctl telling me the key was malformed.
My keys were fine, I’d used them on a previous system. My best guess is boot failed because GPU firmware wasn’t signed with my keys, only Microsoft’s keys. And of course, I can’t just CMOS clear, and I don’t have an iGPU. It’s crazy that an OS can brick my motherboard; I’d be a lot more forgiving if a BIOS option bricked it, but exposing a “brick me” option in efivars for any ring 0 software to press??
OpROMs?
It’s so secure that the first thing under Wikipedia’s entry for Secure boot is Secure boot criticism
Yes this is a real, I’m not joking.
It’s not the first thing, it’s in the middle.
Click the link, you’ll see it is indeed the first heading under Criticism

What’s the first thing under the “Secure boot” section? The section that it automatically scrolls to when clicking my link?

You can set it to run only specifically signed binaries on boot.
Specifically signed by anyone with a key - which, considering multiple where leaked over time - is everyone.
I had this problem at work a week ago or so, at least with Fujitsu PCs. For them, the main cause isn’t an empty CMOS battery, but rather that Fujitsu generally had too little BIOS cache, since there is nothing about it in the UEFI standard. The update basically overfilled that cache, rendering the BIOS completely unusable. The POST doesn’t even go through fully.
The PC are sort of bricked, you gotta put the mainboard into recovery mode, put the ROM file on a freeBSD formatted stick and wait until you see instructions on the screen. Follow them, restart the PC. I recommend setting the BIOS to the optimized default settings, as not doing that might make the boot of Windows pretty slow in some cases. I did hear that it can delete the keys from the TPM, but I haven’t seen that with my PCs at work.

What all am I looking at here? Or is this all meme?
It’s a meme about how draining the cmos battery bricked some PC’s, I think. It’s formatted like the Wikipedia sidebar summary for articles on wartime battles.
You’re in linuxmemes did you not expect a meme? xD
Also: Yes it’s a meme based on a true story (see the other comments for more details)
The meme itself is based on https://knowyourmeme.com/memes/historical-battle-shitposts-decisive-victory

Oh wow thanks
Wow what a super cool website without cookie opt-out.
Not only that, if you try to click any of the links, like the partner list or privacy statements, it takes you to another page with the same pop-up over it… So you have to accept the shit to read their disclosures… What a shitty website, unless the purpose was to keep the information a secret, then it works great because I sure as shit didn’t read it.
The URL (borncity) has nothing to do with the topic (Windows Update), that’s a sign of an SEO content farm
Well the website (and the guy maintaing it) is pretty old. I think the blog posts reach back till Windows Vista. The guy itself wrote some books about Win95 so he has some experience.
The site is quite popular in Germany and the information is usually good summarized and helpful IMHO.
Anyway as always I recommend an adblocker when using the internet.

Allen&Heath sound controllers on Ubuntu had a funny failure too. It’s touchscreen and extra screen would show nothing on boot although the sound controls (for one surface config) works. In order to fix that, you need a replacement battery, a keyboard to boot into it’s BIOS and a password they don’t disclose publicly. I revived a couple of these by a pure luck of discovering someone posting said passwords 5+ years ago. It’s so hostile I hate it.

I still get the shakes
Is this for real?
Yes, multiple of our Windows laptops today couldn’t boot and displayed a BitLocker error message and all affected laptops somehow had an empty BIOS battery…
Can it at least be fixed with a new battery? Or does that get drained quickly too?
AFAIK a new battery + entering the Bitlocker recovery key fixed the problems.
Usually these batteries hold for years. I have a 15+ year old laptop where I had to replace the battery after ~10 years.
However the affected laptops are now a few years old, aren’t designed properly (I heard weird stuff happening like adding additional RAM somehow causes the display to fail) and somehow just have a CR2016 battery installed, not a bigger CR2032. And yes these are buisness-laptops designed for companies -.-
See there’s your problem: you think they are business laptops but actually they might actually be “business” laptops. What’s the difference? Well one is made to actually fulfill the needs so the company can extract the most work out of them, the other is made to sound awesome to unknowing managers and sales people, think all those laptops with “AI” plastered all over the marketing. The only thing those two variants have in common is that you pay out of your nose for them.
