## ✨ What Arc does

Arc turns an x86-64 PC, server or VM into a DSM 7.x machine. You write it to a disk, boot from it, and configure it in the menu — on the machine's screen, or at `http://<loader-ip>:7080` in a browser.

* **Guided setup** — Choose Model → Build Loader → Boot Loader, with DSM version, addons and modules picked for you and changeable before the build
* **Wide hardware support** — 4.4 and 5.10 based platforms, drivers for many controllers and NICs, SATA PortMap and DTS map options for the disk layout
* **Custom kernels** — on the 5.10 platforms with DSM 7.3 and later, choose between Synology's stock kernel and [arc-custom](https://github.com/AuxXxilium/arc-custom)'s kernels with hybrid CPU and wider hardware support
* **Arc Patch** — a serial and MACs for the chosen model, with AME, QuickConnect and more; or bring your own, or use random ones
* **Addons and modules** — select addons (stable and beta) and kernel modules per build
* **Hardware options** — NIC order, fan control, CPU scaling governor, GPU passthrough (IOMMU), USB disks as internal, eMMC and SATA DOM boot
* **DSM options** — edit cmdline and synoinfo, add a user or change a password, allow a DSM downgrade, reset the network config, force-enable SSH, clear blocked IPs and the update cache
* **Web tools** — the web config at `:7080` with a terminal and a file manager, for machines without a screen
* **Loader tools** — backup, restore and recovery, static IP, loader password and ports, clone
