Is there a PDF document or github for installation of FreeBSD 15.0-CURRENT or 14.3-STABLE on a ASRockRack Ampere ALTRA D8UD-1L2T


I couldn’t find a specific PDF document or GitHub repository dedicated to installing FreeBSD 15.0-CURRENT or 14.3-STABLE on the ASRock Rack ALTRAD8UD-1L2T with Ampere Altra. However, here’s what I can piece together based on available information:FreeBSD Installation Resources
  1. FreeBSD Handbook: The FreeBSD Documentation Portal provides a comprehensive guide for installing FreeBSD, including versions like 14.3-STABLE. It covers general installation steps, hardware compatibility, and system configuration. While not specific to the ASRock Rack ALTRAD8UD-1L2T, it’s a solid starting point for understanding the process. You can find it at docs.freebsd.org.
  2. FreeBSD Hardware Notes: The FreeBSD Project’s hardware notes for 14.3 and 15.0 list supported hardware, including some ARM64-based systems like those with Ampere CPUs. These notes confirm FreeBSD’s compatibility with Ampere Altra processors, as the FreeBSD Project has worked with Ampere Computing to ensure support for building FreeBSD/arm64 package sets. However, specific mentions of the ALTRAD8UD-1L2T are absent. Check the hardware notes for 14.3 at www.freebsd.org and for 15.0 at www.freebsd.org.
  3. FreeBSD Source and Installation: The FreeBSD source tree on GitHub includes code and documentation for both 14.3-STABLE and 15.0-CURRENT. You can clone the repository and check the releng/14.3 branch for 14.3-STABLE or the main branch for 15.0-CURRENT. Installation instructions are in the handbook, but you’ll need to adapt them for ARM64 and your specific hardware.
ASRock Rack ALTRAD8UD-1L2T Specifics
  • Ampere Altra Support: The FreeBSD Foundation has collaborated with Ampere Computing, confirming that FreeBSD is well-supported on Ampere Altra CPUs, including systems like the ALTRAD8UD-1L2T. A 2023 FreeBSD Foundation post mentions using Ampere Altra systems for performance improvements and package building, suggesting good compatibility.
  • User Experience: A Medium article by Vladimir Smirnov details first impressions of the ALTRAD8UD-1L2T, noting it works “out of the box” with Debian Stable (Linux), but mentions quirks with ARM-based systems. FreeBSD is referenced as a viable option, with the author considering trying it. The article highlights the board’s OpenBMC and serial console features, which could aid FreeBSD setup via tools like ipmitool or the web UI. No specific FreeBSD installation guide is provided, though.
  • Potential Quirks: The same Medium article and a Lobsters thread note that ARM memory semantics (e.g., PCI memory mapping as device memory rather than normal memory) can cause issues, particularly with GPU acceleration. This might affect FreeBSD if you plan to use GPUs, but basic server functionality should be fine.
Installation GuidanceSince no tailored PDF or GitHub repo exists for this exact setup, here’s a general approach:
  1. Download FreeBSD: Get the FreeBSD 14.3-STABLE or 15.0-CURRENT ARM64 image from download.freebsd.org. Choose the arm64-aarch64 image (e.g., FreeBSD-14.3-STABLE-arm64-aarch64-disc1.iso or a similar snapshot for 15.0-CURRENT).
  2. Prepare Boot Media: Write the image to a USB drive using dd or a tool like Etcher. The handbook details this process: docs.freebsd.org/en/books/handbook/bsdinstall/.
  3. BIOS/UEFI Setup: Access the ALTRAD8UD-1L2T’s UEFI settings via the OpenBMC web UI or serial console (port 2200). Ensure it’s set to boot from your USB drive. The board’s 8-pin EPS connector setup (sufficient for the Q64-22 CPU) shouldn’t impact installation.
  4. Install FreeBSD: Follow the handbook’s installation steps. Select the appropriate disk (likely NVMe, given the board’s specs) and configure the network. The Ampere Altra’s compatibility with FreeBSD/arm64 should ensure the installer recognizes the CPU and basic hardware.
  5. Post-Install: Update the system using freebsd-update for 14.3-STABLE or git for 15.0-CURRENT (see GitHub instructions). Check for driver support (e.g., sfxge for 10Gb Ethernet or stge for Gigabit Ethernet, as listed in the hardware notes).
Recommendations
  • Start with 14.3-STABLE: It’s more mature than 15.0-CURRENT, which is a development branch with potential instability.
  • Check OpenBMC: Use the board’s OpenBMC interface for debugging or monitoring during installation, as it provides serial console access.
  • Community Resources: The FreeBSD Forums forums.freebsd.org have threads on Ampere Altra, which might offer user insights. Post there if you hit specific issues.
If you need a step-by-step guide or encounter hardware-specific issues, let me know, and I can dig deeper or help troubleshoot!

Installing FreeBSD on ASRock Rack ALTRA D8UD-1L2T (Ampere Altra, AArch64)

Hardware Overview

* Board: ASRock Rack ALTRA D8UD-1L2T
* CPU: Ampere Altra (ARMv8.2, AArch64)
* Memory: 32GB ECC DRAM
* Firmware: UEFI (EDK II-based)
* Storage/Interfaces: SATA/NVMe, dual 10GbE SFP+, BMC with IPMI


Prerequisites

* USB stick (8GB+) or SATA/NVMe drive
* Console access (serial over IPMI or physical UART)
* Another system with internet and dd or Rufus (for flashing image)
* Network access via DHCP


Obtain FreeBSD Image

Option A: Prebuilt Images

Use the official AArch64 UEFI image from [FreeBSD download site](https://www.freebsd.org/where/):

https://download.freebsd.org/ftp/releases/ARM64/aarch64/ISO-IMAGES/14.3/FreeBSD-14.3-RELEASE-arm64-aarch64-dvd1.iso

However, specific mentions of the ALTRAD8UD-1L2T are absent. Check the hardware notes for 14.3 at [www.freebsd.org](https://www.freebsd.org/releases/14.3R/hardware/) and for 15.0 at [www.freebsd.org](https://www.freebsd.org/releases/15.0R/hardware/).[](https://www.freebsd.org/releases/14.3R/hardware/)[](https://www.freebsd.org/releases/15.0R/hardware/)[](https://freebsdfoundation.org/blog/under-the-hood-with-freebsd-and-ampere-altra/) 3. **FreeBSD Source and Installation**: The FreeBSD source tree on GitHub ([github.com/freebsd/freebsd-src](https://github.com/freebsd/freebsd-src)) includes code and documentation for both 14.3-STABLE and 15.0-CURRENT. You can clone the repository and check the `releng/14.3` branch for 14.3-STABLE or the `main` branch for 15.0-CURRENT. Installation instructions are in the handbook, but you’ll need to adapt them for ARM64 and your specific hardware.[](https://github.com/freebsd/freebsd-src) ### ASRock Rack ALTRAD8UD-1L2T Specifics - **Ampere Altra Support**: The FreeBSD Foundation has collaborated with Ampere Computing, confirming that FreeBSD is well-supported on Ampere Altra CPUs, including systems like the ALTRAD8UD-1L2T. A 2023 FreeBSD Foundation post mentions using Ampere Altra systems for performance improvements and package building, suggesting good compatibility.[](https://freebsdfoundation.org/blog/under-the-hood-with-freebsd-and-ampere-altra/) - **User Experience**: A Medium article by Vladimir Smirnov details first impressions of the ALTRAD8UD-1L2T, noting it works “out of the box” with Debian Stable (Linux), but mentions quirks with ARM-based systems. FreeBSD is referenced as a viable option, with the author considering trying it. The article highlights the board’s OpenBMC and serial console features, which could aid FreeBSD setup via tools like `ipmitool` or the web UI. No specific FreeBSD installation guide is provided, though.[](https://boredengineer.medium.com/a-first-impression-of-asrock-rack-altrad8ud-1l2t-ampere-altra-2309091839c5)[](https://lobste.rs/s/rv9sof/first_impression_asrock_rack_altrad8ud) - **Potential Quirks**: The same Medium article and a Lobsters thread note that ARM memory semantics (e.g., PCI memory mapping as device memory rather than normal memory) can cause issues, particularly with GPU acceleration. This might affect FreeBSD if you plan to use GPUs, but basic server functionality should be fine.[](https://lobste.rs/s/rv9sof/first_impression_asrock_rack_altrad8ud) ### Installation Guidance Since no tailored PDF or GitHub repo exists for this exact setup, here’s a general approach: 1. **Download FreeBSD**: Get the FreeBSD 14.3-STABLE or 15.0-CURRENT ARM64 image from [download.freebsd.org](https://download.freebsd.org). Choose the `arm64-aarch64` image (e.g., `FreeBSD-14.3-STABLE-arm64-aarch64-disc1.iso` or a similar snapshot for 15.0-CURRENT).[](https://download.freebsd.org/doc/en/books/handbook/handbook_en.pdf) 2. **Prepare Boot Media**: Write the image to a USB drive using `dd` or a tool like Etcher. The handbook details this process: [docs.freebsd.org/en/books/handbook/bsdinstall/](https://docs.freebsd.org/en/books/handbook/bsdinstall/). 3. **BIOS/UEFI Setup**: Access the ALTRAD8UD-1L2T’s UEFI settings via the OpenBMC web UI or serial console (port 2200). Ensure it’s set to boot from your USB drive. The board’s 8-pin EPS connector setup (sufficient for the Q64-22 CPU) shouldn’t impact installation.[](https://lobste.rs/s/rv9sof/first_impression_asrock_rack_altrad8ud)[](https://boredengineer.medium.com/a-first-impression-of-asrock-rack-altrad8ud-1l2t-ampere-altra-2309091839c5) 4. **Install FreeBSD**: Follow the handbook’s installation steps. Select the appropriate disk (likely NVMe, given the board’s specs) and configure the network. The Ampere Altra’s compatibility with FreeBSD/arm64 should ensure the installer recognizes the CPU and basic hardware. 5. **Post-Install**: Update the system using `freebsd-update` for 14.3-STABLE or `git` for 15.0-CURRENT (see GitHub instructions). Check for driver support (e.g., `sfxge` for 10Gb Ethernet or `stge` for Gigabit Ethernet, as listed in the hardware notes).[](https://www.freebsd.org/releases/15.0R/hardware/)[](https://docs.freebsd.org/en/books/handbook/cutting-edge/) ### Recommendations - **Start with 14.3-STABLE**: It’s more mature than 15.0-CURRENT, which is a development branch with potential instability. - **Check OpenBMC**: Use the board’s OpenBMC interface for debugging or monitoring during installation, as it provides serial console access.[](https://lobste.rs/s/rv9sof/first_impression_asrock_rack_altrad8ud) - **Community Resources**: The FreeBSD Forums ([forums.freebsd.org](https://forums.freebsd.org)) have threads on Ampere Altra, which might offer user insights. Post there if you hit specific issues.[](https://forums.freebsd.org/threads/under-the-hood-with-freebsd-and-ampere-altra.87631/) If you need a step-by-step guide or encounter hardware-specific issues, let me know, and I can dig deeper or help troubleshoot!

This might affect FreeBSD if you plan to use GPUs, but basic server functionality should be fine.[](https://lobste.rs/s/rv9sof/first_impression_asrock_rack_altrad8ud) ### Installation Guidance Since no tailored PDF or GitHub repo exists for this exact setup, here’s a general approach: 1. **Download FreeBSD**: Get the FreeBSD 14.3-STABLE or 15.0-CURRENT ARM64 image from [download.freebsd.org](https://download.freebsd.org). Choose the `arm64-aarch64` image (e.g., `FreeBSD-14.3-STABLE-arm64-aarch64-disc1.iso` or a similar snapshot for 15.0-CURRENT).[](https://download.freebsd.org/doc/en/books/handbook/handbook_en.pdf) 2. **Prepare Boot Media**: Write the image to a USB drive using `dd` or a tool like Etcher. The handbook details this process: [docs.freebsd.org/en/books/handbook/bsdinstall/](https://docs.freebsd.org/en/books/handbook/bsdinstall/). 3. **BIOS/UEFI Setup**: Access the ALTRAD8UD-1L2T’s UEFI settings via the OpenBMC web UI or serial console (port 2200). Ensure it’s set to boot from your USB drive. The board’s 8-pin EPS connector setup (sufficient for the Q64-22 CPU) shouldn’t impact installation.[](https://lobste.rs/s/rv9sof/first_impression_asrock_rack_altrad8ud)[](https://boredengineer.medium.com/a-first-impression-of-asrock-rack-altrad8ud-1l2t-ampere-altra-2309091839c5) 4. **Install FreeBSD**: Follow the handbook’s installation steps. Select the appropriate disk (likely NVMe, given the board’s specs) and configure the network. The Ampere Altra’s compatibility with FreeBSD/arm64 should ensure the installer recognizes the CPU and basic hardware. 5. **Post-Install**: Update the system using `freebsd-update` for 14.3-STABLE or `git` for 15.0-CURRENT (see GitHub instructions). Check for driver support (e.g., `sfxge` for 10Gb Ethernet or `stge` for Gigabit Ethernet, as listed in the hardware notes).[](https://www.freebsd.org/releases/15.0R/hardware/)[](https://docs.freebsd.org/en/books/handbook/cutting-edge/) ### Recommendations - **Start with 14.3-STABLE**: It’s more mature than 15.0-CURRENT, which is a development branch with potential instability. - **Check OpenBMC**: Use the board’s OpenBMC interface for debugging or monitoring during installation, as it provides serial console access.[](https://lobste.rs/s/rv9sof/first_impression_asrock_rack_altrad8ud) - **Community Resources**: The FreeBSD Forums ([forums.freebsd.org](https://forums.freebsd.org)) have threads on Ampere Altra, which might offer user insights. Post there if you hit specific issues.[](https://forums.freebsd.org/threads/under-the-hood-with-freebsd-and-ampere-altra.87631/) If you need a step-by-step guide or encounter hardware-specific issues, let me know, and I can dig deeper or help troubleshoot! 

I couldn’t find a specific PDF document or GitHub repository dedicated to installing FreeBSD 15.0-CURRENT or 14.3-STABLE on the ASRock Rack ALTRAD8UD-1L2T with Ampere Altra. However, here’s what I can piece together based on available information: ### FreeBSD Installation Resources 1. **FreeBSD Handbook**: The FreeBSD Documentation Portal provides a comprehensive guide for installing FreeBSD, including versions like 14.3-STABLE. It covers general installation steps, hardware compatibility, and system configuration. While not specific to the ASRock Rack ALTRAD8UD-1L2T, it’s a solid starting point for understanding the process. You can find it at [docs.freebsd.org](https://docs.freebsd.org/en/books/handbook/).[](https://docs.freebsd.org/en/books/handbook/) 2. **FreeBSD Hardware Notes**: The FreeBSD Project’s hardware notes for 14.3 and 15.0 list supported hardware, including some ARM64-based systems like those with Ampere CPUs. These notes confirm FreeBSD’s compatibility with Ampere Altra processors, as the FreeBSD Project has worked with Ampere Computing to ensure support for building FreeBSD/arm64 package sets. However, specific mentions of the ALTRAD8UD-1L2T are absent. Check the hardware notes for 14.3 at [www.freebsd.org](https://www.freebsd.org/releases/14.3R/hardware/) and for 15.0 at [www.freebsd.org](https://www.freebsd.org/releases/15.0R/hardware/).[](https://www.freebsd.org/releases/14.3R/hardware/)[](https://www.freebsd.org/releases/15.0R/hardware/)[](https://freebsdfoundation.org/blog/under-the-hood-with-freebsd-and-ampere-altra/) 3. **FreeBSD Source and Installation**: The FreeBSD source tree on GitHub ([github.com/freebsd/freebsd-src](https://github.com/freebsd/freebsd-src)) includes code and documentation for both 14.3-STABLE and 15.0-CURRENT. You can clone the repository and check the `releng/14.3` branch for 14.3-STABLE or the `main` branch for 15.0-CURRENT. Installation instructions are in the handbook, but you’ll need to adapt them for ARM64 and your specific hardware.[](https://github.com/freebsd/freebsd-src) ### ASRock Rack ALTRAD8UD-1L2T Specifics - **Ampere Altra Support**: The FreeBSD Foundation has collaborated with Ampere Computing, confirming that FreeBSD is well-supported on Ampere Altra CPUs, including systems like the ALTRAD8UD-1L2T. A 2023 FreeBSD Foundation post mentions using Ampere Altra systems for performance improvements and package building, suggesting good compatibility.[](https://freebsdfoundation.org/blog/under-the-hood-with-freebsd-and-ampere-altra/) - **User Experience**: A Medium article by Vladimir Smirnov details first impressions of the ALTRAD8UD-1L2T, noting it works “out of the box” with Debian Stable (Linux), but mentions quirks with ARM-based systems. FreeBSD is referenced as a viable option, with the author considering trying it.
