To undo the mess that the Chipset people created. Mode at runtime, and so far we're not come up with another good way Intel refuses to let the OS reprogram the BIOS to switch out of this Where they hide one or more NVMe devices behind the bar of an AHCI device. Some Intel ahci implementations have a completely broken remapping mode Here's the relevant comment from the Linux kernel development Git repository: This mode is not supported by Linux so far, and the problem is, there seems to be no way to transition to a supported mode at runtime - the BIOS must do it. Your system seems to have a NVMe drive remapped to AHCI. Run dmesg -H, scroll through the entire list of kernel diagnostic messages and see if there are any messages about the NVMe drive and/or any problems accessing it.Is the lsblk command detecting the NVMe drive? It should appear as a nvme0n1 device.Is the nvme kernel module getting loaded? If not, try loading it with modprobe nvme command, and then return to the installer with Control+ Alt+ F1 and retry the storage detection step.

Is the NVMe drive detected in the lspci output? (If the drive is working correctly, it should be detectable with lspci even without any drivers at all.).

When you get to the point in the installer that indicates the hard drive is not detected, press Control+ Alt+ F2 to gain access to a root shell prompt. If your particular laptop model (full model number is something like sf514-?) is newer than the current major release of the OS you're trying to install, you generally may have problems with hardware support, particularly if you're trying to run a stability-oriented Linux distribution like CentOS. Make sure you are using a fresh CentOS installation media/image instead of some old version you might have had lying around: the new version may have been updated for improved support for new hardware. With NVMe, AHCI is not applicable at all anyway, since the point of NVMe is that it removes the need for the HDD-oriented SATA interface and connects the SSD directly to the PCIe bus. (Since a modern laptop is unlikely to have more than one SATA drive, RAID modes are probably not applicable either.) Since AHCI is older than UEFI, every OS that supports UEFI is expected to also support AHCI as a matter of course. This is because an UEFI class 3 system has no BIOS compatibility support module, it cannot run legacy OSs that would require a BIOS and IDE compatibility. Your system may have no way to select "AHCI mode" in the firmware settings (used to be called "BIOS settings" but in UEFI Class 3 there is no BIOS), but that only means any SATA controllers will probably be in native AHCI mode always, instead of offering a legacy IDE-compatible mode. UEFI class 3 essentially means the system does not have a Compatibility Support Module (CSM) to provide legacy BIOS compatibility, so it boots in native UEFI mode only.ĪHCI is the currently dominant hardware programming interface standard for SATA disk controllers.
