Booting HP PC with Unidentified OS (pfSense) from Serial Port on a Macbook Pro M1
In this article, we will discuss the steps required to boot a HP PC with an unidentified Operating System (pfSense) using a Serial Port on a Macbook Pro M1. The process involves downloading an AMD64 Memstick USB image and using it to create a bootable USB drive. We will also cover some key concepts and provide detailed context on the topic.
What is pfSense?
pfSense is a free and open-source firewall and router software distribution based on FreeBSD. It is widely used for network security and traffic management purposes. pfSense can be installed on various hardware platforms, including HP PCs.
Downloading the AMD64 Memstick USB Image
The first step in the process is to download the AMD64 Memstick USB image for pfSense. This image can be downloaded from the official pfSense website. It is important to note that the Memstick USB image is specific to the AMD64 architecture, which is why it is necessary to download this image for installation on a HP PC.

Creating a Bootable USB Drive
Once the Memstick USB image has been downloaded, the next step is to create a bootable USB drive. This can be done using a variety of tools, such as Etcher, Rufus, or the dd command in Linux. In this example, we will use the dd command in Linux to create a bootable USB drive.
gunzip pfSense-memstick-AMD64-2.5.2-RELEASE-p1.img.gz
sudo dd if=pfSense-memstick-AMD64-2.5.2-RELEASE-p1.img of=/dev/sdX bs=1M
Note: Replace /dev/sdX with the correct device identifier for your USB drive.
Setting up the Serial Console
With the bootable USB drive created, the next step is to set up the serial console on the Macbook Pro M1. This can be done by connecting a USB-C to USB-A adapter to the Macbook Pro M1, and then connecting a serial cable from the adapter to the HP PC. Once the serial cable is connected, the serial console can be configured using a terminal emulation program such as screen or minicom.
screen /dev/tty.usbserial-0001 9600
Note: Replace /dev/tty.usbserial-0001 with the correct device identifier for your serial console.
Booting pfSense from the USB Drive
Now that the serial console is set up, the HP PC can be powered on and booted from the USB drive. This will initiate the pfSense installation process, which can be monitored and controlled through the serial console.
