Self-Hosting HP UEFI BIOS Updates via Local HTTP (Elitedesk 800 G5)
Self-Hosting HP UEFI BIOS Updates via Local HTTP
HP commercial desktops (like the EliteDesk 800 G5) support network BIOS updates from the UEFI setup screen. However, modern HP endpoints enforce HTTPS/TLS configurations that older UEFI network stacks cannot negotiate, resulting in network connection failures.
You can resolve this by mirroring HP's upstream files and hosting them over plain HTTP (Port 80) from any secondary machine on your local network.

I've finally sat down and completed my network migration from my ISP's (Telia LT) GPON terminal over to my own router using SFP module.
This guide will provide step by step guide, how to do that.
To do that, you need a few things prior to starting, namely:
GPON SFP(+) module with an unlocked serial number configuration (e.g. here),
A packaging script for creating distributable archives of software built in MSYS2.

Creating Templates and Virtual Machines on Proxmox using cloud images from various Linux distributions.
5 Steps for Creating Templates and Virtual Machines on Proxmox using Linux Distro's Cloud Images
This tutorial guides you through the process of creating Templates and Virtual Machines on Proxmox using cloud-based images from various Linux distributions. We provide clear instructions for Alma Linux 9, Amazon Linux 2, CentOS 9, Fedora 38, Oracle Linux 9, RHEL 9, Rocky Linux 9, and Ubuntu 23.04 Lynx Lobster.
Note: The instructions have been tested on Proxmox 8.0.4.
Let's begin by choosing the cloud-based image. If you already have your preferred Linux distribution, skip to the 1st step.
To assist in making informed choices when selecting a Linux distribution for your virtual machines, we've compiled a table showcasing key characteristics of each cloud image. This table provides a snapshot of important attributes, including kernel version, Python version, number of processes initialized after boot, number of packages installed, free memory after boot, VM disk size, root partition disk size, used size on t
