That's called CSM, and Intel removed it in late 2020. I'm not sure if AMD still has it, but they still have S3 sleep afaik. Go Team Red for your next buy, I am too.
My HP crapbook doesn't have this OEM logo bullshit. Only the windows bootloader shows it, and the logo file is stored in the BGRT. So I don't think I'm affected unless the WBM or systemd-boot have this vuln.
Mine:
1. Screen turns on
2. I pick EndeavorOS in systemd-boot
3. It starts spitting out logs (I love this behavior)
4. It switches modes once the backlight is loaded
5. I log in
6. KDE loads
I will never understand people who install Plymouth, it just adds complexity in the boot process. If your distro installs this then I understand why: so it doesn't look like you're "hacking the government". If your distro doesn't install it and you install it then you probably picked the wrong distro.
I'm a teenager and I don't talk like that.
Just:
Capitalize your sentences Stop spamming emoticons, emojis, and exclamation marks Don't be naive Use common sense
And you'll be fine.
