== SATA Port multiplier (PMP) ==

It [http://forum.lemaker.org/thread-9207-1-1.html used to be necessary] to make some changes to the kernel source and recompile, but on recent linux versions (including the one shipped with the NixOS arm image) this is no longer necessary. Instead, all that is required is merely to set <syntaxhighlight lang="nix">boot.kernelParams = ["ahci_sunxi.enable_pmp=1"]</syntaxhighlight> in <code>configuration.nix</code>. Note that this will prevent the use of a hard drive connected to the SATA port directly without a port multiplier in between.

See [https://linux-sunxi.org/SATA#PMP_support_-_using_SATA_port_multipliers_with_sunxi_devices here] for more details.
