Hi Colin, > The efivarfs module was not found in the initrd
I would like to make sure any new module requirements are also compatible with systems booting in legacy BIOS mode. The Wikipedia article for Intel RST states: > When booting in a BIOS environment (legacy) and some / EFI, the RST option > ROM is used. When booting in a true UEFI environment the Option ROM is not > used as a SataDriver with the RST version takes over. In BIOS mode the > legacy/BIOS booting is under CSMCORE. In true UEFI mode the RST is > controlled under SataDriver in BIOS. [1] The article suggests that some people use IMSM arrays in legacy BIOS mode. Does mdadm support IMSM only when the system is booted in UEFI mode? Sorry that I do not know the answer to that question. I just assumed maintenance of mdadm and do not use IMSM. At this point, I am reading code. Thank you! Kind regards Felix Lechner [1] https://en.wikipedia.org/wiki/Intel_Rapid_Storage_Technology#Matrix_Storage_Manager_option_ROM
