### Minimum requirements for Phyllome OS Desktop
|
||||
|
||||
* **x86-64** computer that supports the first generation of hardware-assisted virtualization features
|
||||
* For AMD-based configurations, it means that AMD V is available and enabled, which is the case for most CPU models.
|
||||
* For AMD-based configurations, it means that AMD V is available and enabled (*see next section bellow to learn how to enable this feature*)
|
||||
* For Intel-based configurations, it means that Intel VT-x is available and enabled
|
||||
* **2-core** processor
|
||||
* **4 GB** of RAM

## 2. Enable hardware-assisted virtualization
|
||||
|
||||
### Access the firmware
|
||||
Unfortunately, even on supported computer platforms, hardware-assisted virtualization is rarely turned on by default.
|
||||
|
||||
*The Open Virtual Machine Firmware (OVMF), which is based on the TianoCore firmware, is the default firmware for EFI-based virtual machines. It can be accessed using the <kbd>Esc</kbd> key.*
|
||||
In other words, it is not enough for a computer platform to support hardware-assisted virtualization: it is very likely that it has to be explicitly enabled.
|
||||
|
||||
The process to activate this feature requires accessing the firmware configuration tool for your motherboard, which is part of your BIOS or UEFI.
|
||||
|
||||
This process is described in the following section.
|
||||
|
||||
> *Did you know that the Open Virtual Machine Firmware (OVMF), which is based on [TianoCore](https://www.tianocore.org/), is the default firmware for EFI-based virtual machines? Its configuration utility can be accessed using the <kbd>Esc</kbd> key.*
|
||||
{.is-info}
|
||||
|
||||
*The TianoCore splash screen*
|
||||
|
||||
|
||||
|
||||
* **Since Windows 8**: command-line instructions
|
||||
### Accessing the firmware
|
||||
|
||||
The process to access the main motherboard firmware configuration utility differ depending on which operating system is currently installed on your computer.
|
||||
|
||||
#### Windows 8 and newer: command-line instructions
|
||||
|
||||
Press the <kbd>Win</kbd> and <kbd>X</kbd> keys simultaneously to make a context menu appears. Then press <kbd>Shift</kbd> and <kbd>a</kbd> to politely ask Windows to open `Powershell` using elevated privileges, and click on the `Yes` button to bypass the User Account Control pop-up. Finally, input the following command inside the command prompt and press `enter`.
|
||||
|
||||
```
|
||||
shutdown /fw /r
|
||||
```
|
||||
* **Since Windows 8**: a visual walk-through
|
||||
#### Windows 8 and newer: a visual walk-through
|
||||
|
||||
* Open the start-up menu and write `start-up`, then select *Change advanced start-up options*
|
||||
* Open the start-up menu and write "start-up", then select *Change advanced start-up options*
|
||||
|
||||
|
||||
|
||||
* Under the *Advanced start-up* section, click on `Restart now`
|
||||
* Under the *Advanced start-up* section, click on *Restart now*
|
||||
|
||||
|
||||
|
||||
* Select `Troubleshoot`
|
||||
* Select *Troubleshoot*
|
||||
|
||||
|
||||
|
||||
* Then select `Advanced options`
|
||||
* Then select *Advanced options*
|
||||
|
||||
|
||||
|
||||
* Select `UEFI Firmware Settings`
|
||||
* Select *UEFI Firmware Settings*
|
||||
|
||||
|
||||
|
||||
* Hit `Restart`
|
||||
* Hit *Restart*
|
||||
|
||||
|
||||
|
||||
* **macOS-based computers**
|
||||
#### macOS-based computers
|
||||
|
||||
Hardware-assisted virtualization is a hit or miss on Apple computers, as there is no way to access the firmware configuration tool on these computers. Apple users can go to the [install section](https://wiki.phyllo.me/deploy/medium) directly, create a USB stick and hope that hardware-assisted virtualization will be supported.
|
||||
|
||||
* **Other computers**
|
||||
#### Other computers
|
||||
|
||||
Make sure the targeted computer is shut down.
|
||||
|
||||
During the POST phase, you need to press a certain key to access the firmware configuration tool for your motherboard, which is part of your BIOS or UEFI.
|
||||
|
||||
Just after pressing the `power-on` button, hit the right key to access the firmware configuration tool, usually <kbd>F2</kbd> or <kbd>Del</kbd>, but it may be another keystroke on your model.

> Do not hesitate to repeatedly press the pertinent key as soon has your computer has started, to make sure it is registered.

Unfortunately, most firmware configuration tool do differ, and the steps here might not be identic on your own platform. In general, the sought after features are found under the `security` tab.

For an AMD-based computer, you need to look for references to `AMD SVM`, AMD V or AMD Vi. Conversingly, for an Intel-based computer, you need to look for `Intel VT-x` and `Intel VT-d`. It is also possible that the feature will be refered simply to as `virtualization`. In that case, you may not know it refers to IOMMU-based hardware-assisted virtualization or not.

|
||||
|
||||
Make sure you enable these options and choose to *save and exit* the configuration tool, which will reboot your computer.
|
||||
|
||||
> While you are there, you could also change the boot order, to make sure that your computer will boot from an attached USB thumb drive first when it will be time to try out Phyllome OS.

If, for some reasons, it cannot be activated on your computer, for example because of a lack of hardware support, you would be better off picking a Linux distribution which doesn't require it, such as [Debian](https://www.debian.org/distrib/).
