A quick check with ChatGPT shows (among other things): * Some M.2 slots disable SATA ports when in use. * PCIe lanes may be shared between: - Multiple M.2 NVMe SSDs - Wi-Fi cards - SATA ports - Secondary GPU slots Presumably one or more of these affected you (and perhaps the OP), but details depend on the motherboard. poc -- _______________________________________________ users mailing list -- [email protected] To unsubscribe send an email to [email protected] Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/[email protected] Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
