## Installation

RAID mode is enabled by default. AHCI mode must be used, otherwise the disks will be invisible[1]. Using RAID mode will trigger a relevant log message in the journal.

## Firmware

fwupd supports this device.

### Firmware data path

The BIOS stores logs and recovery images in `esp/EFI/Dell`. Recovery images are stored in `esp/EFI/Dell/bios/recovery` and are 14 MB in size. It appears that there will only be two images at the same time, `BIOS_CUR.rcv` and `BIOS_PRE.rcv`. Those files will be created when the BIOS was updated.

#### Logs

`esp/EFI/dell/logs` contains XML files which contain diagnostics data (SupportAssist). It appears that there will only be two logs at the same time, `diags_previous.xml` and `diags_current.xml`. Those files will be created when an error happened.

## Power management

After waking up the device from suspend, input lag will occur for approximately 5-10 seconds.
