Hi, I am currently building a new PC. Migrating the drives from an Intel Celeron with integrated GPU, mobo Gigabyte GA-B85M-D3H to an Intel Core i3 13th Gen, mobo Gigabyte B760M DS3H DDR4 does cause some issues. The PC is a Linux multi-boot machine. The old SATA SSDs are all MBR drives, a new NVMe SSD is a GPT drive. The old PC's bootloader is syslinux. The Arch install's root directory holds all kernels, the Arch kernels, but also the kernels from the other Linux installs (an ancient Suse, Ubuntu etc.). Disabling Intel platform trust technology and secure boot works, but enabling CSM (legacy boot) fails. I read that on modern Intel machines CSM cannot be enabled, when using the internal GPU. I wonder if this is correct?! I also read, if I need to stay with EFI boot, that continuing using syslinux for a multi-boot Linux machine without chainloading, by keeping all kernels in one partition, could become a PITA or even impossible. Does anybody know, if it's possible to enable CSM? Maybe I forgot to disable or enable something else, before enabling CSM can work. As a temporarily workaround, to continue building the new PC, I installed Xubuntu, from a pendrive that was at hand. It installed GRUB2, so I can boot Arch Linux from the old MBR drive. If I should need to stay with CSM disabled and if syslinux should not work to boot all Linux installs, is there another alternative bootloader available that is similar to syslinux? If possible I will not stay with GRUB2. FWIW aur/r8125-dkms (chaotic-aur/r8125-dkms) works without issues [1]. Thank you aravance! Regards, Ralf [1] https://aur.archlinux.org/packages/r8125-dkms
