# Generic x86_64 System
[](https://circleci.com/gh/nerves-project/nerves_system_x86_64/tree/master)
This is the base Nerves System configuration for a generic x86_64 system.
| Feature | Description |
| -------------------- | ------------------------------- |
| CPU | Intel |
| Memory | 512 MB+ DRAM |
| Storage | Hard disk/SSD/etc. (/dev/sda) |
| Linux kernel | 4.13 |
| IEx terminal | Display - tty0 |
| Hardware I/O | None |
| Ethernet | Yes |
Please contact me about this if you're really interested in it. I don't
maintain it, and unless you really dig through the code, it's not going
to be obvious how it works. I'm happy to help if you're really interested.
## Installation
Add `nerves_system_x86_64` to your list of dependencies in mix.exs:
```
def deps do
[{:nerves_system_x86_64, "~> 0.1"}]
end
```
## Root disk naming
If you have multiple SSDs, or other devices connected, it's
possible that Linux will enumerate those devices in a nondeterministic order.
This can be mitigated by using `udev` to populate the `/dev/disks/by-*`
directories, but even this can be inconvenient when you just want to refer to
the drive that provides the root filesystem. To address this, `erlinit` creates
`/dev/rootdisk0`, `/dev/rootdisk0p1`, etc. and symlinks them to the expected
devices. For example, if your root file system is on `/dev/mmcblk0p1`, you'll
get a symlink from `/dev/rootdisk0p1` to `/dev/mmcblk0p1` and the whole disk
will be `/dev/rootdisk0`. Similarly, if the root filesystem is on `/dev/sdb1`,
you'd still get `/dev/rootdisk0p1` and `/dev/rootdisk0` and they'd by symlinked
to `/dev/sdb1` and `/dev/sdb` respectively.
