Polprog's Am5x86 based retro UNIX build log (https://polprog.net/blog/486/)
I have recently acquired an Am5x86 computer, in a surprisingly good condition. This is an ongoing project, check this page often for updates!
I began by connecting a front panel. The panel came from a different chassis and is slightly too wide, so I had to attach it with a couple of zip-ties. However, that makes it stick out from the PC front at an angle, allowing easy access when the computer sits at the floor - and thats where it is most of the time. It's not that bad, to be honest, and its way easier to access than it would be, if mounted vertically
There is a mains switch on the front panel because the computer uses an older style power supply. Those power supplies instead of relying on a PSON signal, like modern ATX supplies, run a 4 wire cable to a mains switch. The cable carries live and neutral both ways, and the switch keys in or out the power. The system powers on as soon as the switch is enabled.
Originally there was no graphics card in it. Since a PC will not boot with out a GPU, I had to find one. The mainboard only has PCI and ISA slots, and all the GPUs I had were AGP. Fortunately, I bought a PCI GPU hoping it would solve my issue...
However the GPU turned out to be faulty. It took me some time to repair it. I had to repair a broken trace leading to one of the EEPROM pins, and replace a contact in the EEPROM's socket. Then I replaced all the electrolytic capacitors on it, and that fixed it for good.
Having used up only one of the three PCI slots, I populated the remaining pair with two ethernet cards. I still have a bunch of ISA slots available, but I have nothing to install there. Yet.

Setting up services in a FreeNAS Jail (https://www.ixsystems.com/blog/services-in-freenas-jail/)
This piece demonstrates the setup of a server service in a FreeNAS jail and how to share files with a jail using Apache 2.4 as an example. Jails are powerful, self-contained FreeBSD environments with separate network settings, package management, and access to thousands of FreeBSD application packages. Popular packages such as Apache, NGINX, LigHTTPD, MySQL, and PHP can be found and installed with the pkg search and pkg install commands.
This example shows creating a jail, installing an Apache web server, and setting up a simple web page.
NOTE: Do not directly attach FreeNAS to an external network (WAN). Use port forwarding, proper firewalls and DDoS protections when using FreeNAS for external web sites. This example demonstrates expanding the functionality of FreeNAS in an isolated LAN environment.

First taste of DragonflyBSD (https://nanxiao.me/en/first-taste-of-dragonfly-bsd/)
Last week, I needed to pick a BSD Operating System which supports NUMA to do some testing, so I decided to give Dragonfly BSD a shot. Dragonfly BSDonly can run on X86_64 architecture, which reminds me of Arch Linux, and after some tweaking, I feel Dragonfly BSD may be a “developer-friendly” Operating System, at least for me.
I mainly use Dragonfly BSD as a server, so I don’t care whether GUI is fancy or not. But I have high requirements of developer tools, i.e., compiler and debugger. The default compiler of Dragonfly BSD is gcc 8.3, and I can also install clang 8.0.0 from package. This means I can test state-of-the-art features of compilers, and it is really important for me. gdb‘s version is 7.6.1, a little lag behind, but still OK.
Furthermore, the upgradation of Dragonfly BSD is pretty simple and straightforward. I followed document to upgrade my Operating System to 5.6.0 this morning, just copied and pasted, no single error, booted successfully.
