How to Install DSM to Old NAS? XPEnology RAID Recovery

Do you have an old NAS Acer H340 and you don’t know how to make it work again? In this article, we’ll tell you how to install Synology DSM on a computer with the help of Xpenology bootloader, and how to bring back to life an old NAS storage system Acer Aspire H340, which lacks network access.

How to Install DSM to Old NAS? XPEnology RAID Recovery

XPEnology is not a Linux operating system like Ubuntu or another popular distribution. On the contrary, it’s a bootloader for Synology DSM operating system which is used with NAS devices. DSM runs on a special version of Linux developed by Synology, so this system cannot be compared directly with Linux distributions for desktop and server use. This particular one is optimized to work with NAS devices and make the best of their functionality.

XPEnology lets you run DSM on any device – for example, on an old computer, server or NAS storage system. This way, you can turn it into a hardware-based network storage device with multimedia and cloud-based features offered by DSM (DiskStation Manager) operating system.

DiskStation Manager (DSM) is an intuitive operating system with a web interface that helps users manage their files in the network-attached storage. Below, you will find a complete step-by-step tutorial on how to install the DSM operating system on an Acer H340 NAS with the help of XPEnology bootloader. With this tutorial, you’ll be able to install this operating system on any similar device or computer.

In my case, I failed to reset this NAS device and install a standard operating system, so I decided to install a DSM operating system instead, and do it with the XPEnology bootloader.

How to connect a graphics card to Acer H340

With this NAS model, you can connect a graphics card for further configuration. When trying to do that, we discovered that the operating system cannot complete the installation from the integrated flash memory, and that is why this device is not available over the network.

An Х1 to Х16 adapter

To display images, we will need a graphics card supporting PCIEx X1. As this is not a very popular type of graphics, I used a special Х1 to Х16 adapter.

Configure booting from USB drive

Now we need to get into BIOS to configure booting from an external USB drive.

To enter BIOS, set the jumper and connect these two contacts – while the device is powered off. After that, connect a USB drive containing the bootloader, and connect the keyboard, the mouse, and the network cable.

To enter BIOS, set the jumper and connect these two contacts

Power on the NAS, and press the F2 key to enter BIOS.

Press the F2 key to enter BIOS

Jump to the Boot tab, find the USB drive on this list and move it to the top by pressing the plus button.

Jump to the Boot tab, and move the USB drive to the top of the list

Press the F10 key to save the new settings and restart the device, and now your NAS will boot from the USB drive. To reset the settings, just remove the jumper.

How to create a bootable USB drive with XPEnology bootloader

Now that we’re finished with configuring the device itself, let’s explore how to install DSM. To simplify this process, download the utility called XPEnology Tool.

Now you need to decide which version of Synology DSM should be installed, and this choice depends on the type of motherboard inside your computer. If it’s an old one that lacks UEFI support, it’s recommended to use DSM 5.2 or try DSM 6.2.1 with bootloader version 1.04b.

Start XPEnology Tool, open the Downloads tab, select the required bootloader version here; I need version 1.03 for device DS3617; it’s a well-tried bootloader version.

Start XPEnology Tool, open the Downloads tab

Download the archive

Download the archive

After that, you will need to download the corresponding version of DSM – 6.2 – 1.03 – DS3617.

Download DSM

Extract the archive containing the image file synoboot.ISO, and copy a file with the extension .path into the same folder.

Now you can create a bootable USB drive. This USB drive will become a part of the system from which initial drivers and loader will be booted; for this purpose, even an old 4GB USB stick will do. After that, you should mount the bootloader image and edit it a little.

In the XPEnology Tool window, open the tab “Portable tools” and run the OSF Mount utility.

In the XPEnology Tool window, open “Portable tools” and run OSF Mount

Click “Mount new”, give the path to the ISO image file, select it and click “Open”, choose Partition 0 here or type 2048 into this field; below, uncheck the box for “Read-only” and check the box for “Mount as removable media” – click OK.

Mount the ISO image for DSM

Double-click on it to open, jump to the folder “grub” to find a file with the name grub.cfg and open it with Notepad. In this file, you need to replace the “vid” and “pid” fields by adding your USB drive values instead. You can find these values in the drive properties.

Jump to the folder “grub” to find a file grub.cfg

From XPEnology Tool, run the program “USB Device view” – the USB drive is displayed as Mass Storage; to make sure this is the one we need, click on it to open. Copy and transfer the values Product and Vendor ID to the .cfg file.

Product and Vendor ID copied to the .cfg file

After that, there is one more value to change – the device serial number, in this field. To obtain a serial number, run a utility called “Serial generator,” select the model here – according to the downloaded files it is DS3617 – and click “Generate”. Copy it and paste into the file, then save the changes. Dismount it in OSF Mount and exit the program.

Your device’s serial number

Now this modified image should be copied to a previously prepared USB drive. Open Rufus and create a bootable drive. Select the drive, then the image file, and click “Start”.

How to install Synology DSM

Now that the bootable drive is ready, you can begin the installation. Disconnect the USB drive from the computer and stick it into the network-attached storage. Power on the NAS. Previously, I configured its BIOS to boot from USB, and if everything works as planned, you will see this black screen with white letters. Choose the first option and press Enter. The bootloader is ready for installation.

Select the bootloader

To begin, go to the computer from where you want to manage this device, and start Synology Assistant, then let it get through the firewall. When the program is ready, it starts looking for devices. A DiskStation device should appear on the list with the status “Not installed”. Select it and click “Connect”.

Connect to a DiskStation device

In the browser window that opens, you will see the startup screen for DSM installation. Click “Set Up” here, and then choose “Manual Install”.

Give the path to the previously downloaded .path file, and click “Install Now”. A pop-up window warns you that all data will be erased from this disk – agree and click OK. It starts the process of partition formatting and installation. The time required for completion depend on the speed of your hard disk. Wait until the device reboots. In a few minutes after the reboot, the NAS should appear on the network.

Give the path to the previously downloaded .path file

The operating system is installed, so now you should give the server name, username and password.

Disable automatic updates, select the notification schedule from the list and click “Next”. It’s better to skip QuickConnect for the unofficial version; if necessary, you can configure it later. This is the end of DSM installation – your device is ready to use. Now you can build a RAID system, set up network access and add shared folders.

This is the end of DSM installation
