* ''Disable Intel hardware RAID and use AHCI instead.'' Intel doesn't seem to provide a working linux driver for this. (If you just have SSD it's pointless and just slows things down needlessly anyways.)
=== Wifi ===
~~Wifi does not work with kernels older than 5.1 (firmware not present) or newer~~ (https://bbs.archlinux.org/viewtopic.php?id=247705)
Update: The 48.ucode causes the Killer wifi card to crash. The iwlfwifi-cc-a0-46.ucode works perfectly.
default.nix contains an overlay that removes the offending ucode from the linux-firmware bundle.
To use it one also needs to enable unfree firmware in their own configuration (<code>hardware.enableRedistributableFirmware = true;</code>)
```
# Use the systemd-boot EFI boot loader.
boot.loader.systemd-boot.enable = true;
boot.loader.grub = {
device = "nodev";
efiSupport = true;
efiInstallAsRemovable = true;
};
boot.loader.efi.canTouchEfiVariables = true;
boot.kernelPackages = pkgs.linuxPackages_5_1;
```
Disable the `canTouchEfiVariables` after a boot or two to prevent NVRAM wearout.
=== After installation ===
* ''Add systemd-boot to UEFI boot list.'' The (uneditable anyways) settings mapping drive UUIDs to HD* work fine.

* ''Update BIOS.'' According to Reddit, this helps with battery life.
=== Troubleshooting ===
== Firmware updates ==
This device is supported by [https://fwupd.org/ fwupd].
You may use <code>fwupdmgr</code> to perform firmware updates.
== Power management ==
Deep sleep is preferred to the default S2 sleep mode, in order to reduce battery draining during suspend.
