    Hi cakgo1530

    A315‑54‑57VU & “PCIe switches” The BIOS on this model has no support for PCIe lane bifurcation or configurable “PCIe switches.” There are no options to split lanes or alter PCIe routing — you can’t enable or tweak it in firmware.

    Storage Upgrade Facts

    • The system will boot only from the primary M.2 slot (SSD #1). Any second slot, if present, is for storage only.
    • That primary slot accepts M.2 SATA or PCIe Gen3 NVMe drives; both are supported up to at least 1 TB.
    • A swap from the factory drive to a faster Gen3 NVMe (e.g., Crucial P3 Plus or Samsung 970 EVO Plus) is straightforward and will be recognised by the BIOS.

    Bottom Line If the goal is simply “faster storage,” skip the PCIe switch jargon and replace the SSD in slot #1. Keep any additional drive in slot #2 for data only — it won’t be bootable on this model.
