[brag + followup] configured and compiled a kernel for the first time ever 🛠️ Following the Arch wiki, I built a custom kernel for the first time ever. It was easier that I thought it’d be, probably because the Arch wiki is so thorough and because I didn’t make that many changes… I just enabled a few FireWire related options as per this guide in order to work on this project (or this). Results/takeaways The OS ran fine with the new kernel 💃 I learned how to manually create GRUB entries 🔧 I learned that I don’t even have to create new GRUB entries, since I can simply point to the new kernel image and initramfs from the bootloader menu 🪛 I learned that my 5800X3D runs well (compiles the new kernel blazingly fast) with all cores set to negative 30 in the UEFI FireWire is dead 💀 Tiny followup on that project That old GPU did something to the UEFI (possibly CMOS?), because even after removing all potentially incompatible hardware and reinstalling my modern GPU, I still got that same error message, saying that the system was forces to boot in CSM mode. Only by resetting the UEFI settings was I able to restore the system to a working state. I admit, I panicked.

Just a little update: effed by the archaic Geforce GT 220 somehow 😅 Here I thought I had been insanely smart to buy a GPU from 2010 for $10 since the CPU is going to do all the encoding anyway. And because my previous card, a honking 3080, wouldn’t have allowed for the other two capture cards to be installed, taking up all the real estate. I have been trying to setup an Artix system on my own for two hours now, but GRUB won’t install in CSM mode… I’ve tried UEFI on GPT, BIOS on MBR, BIOS on GPT… 😅 Boot partition with and without file system… 💀 I’ll just buy a more modern yet slim card, I guess? Unless I wake up tomorrow and give researching the issue a chance. Night👋🔌

Does Libreboot prevent unauthorized USB boot, aka somebody boot another OS and wipe your drive? I understand LUKs can be used to encrypt your data. But what would prevent somebody plug in a USB with and just wipe my drive? On traditional BIOS like Lenovo, HP, Dell and even Framework you can set a supervisor password that locks the boot menu. So nobody can boot from the USB. Coreboot is different though. I spoke with Starlabs whose computers run Coreboot, and apparently you can have the boot menu password. OTOH, Sys76’s Coreboot doesnt allow such things. I ask because i want to libreboot my T480, but the number 1 thing i worry is unauthorized USB boot. This one: libreboot.org/docs/linux/grub_hardening.html#grub… seems to only lock the ability to edit the grub entry freely, aka press “e” to change stuff when grub fails to boot.
