@socksinspace & @birdgoose, thanks for your advice!

Unfortunately I wasn't able to install NetBSD. The computer always rebooted a few seconds after the apparition of the first blue screen. I tried to install OpenBSD, it worked but I did not succeed to connect my computer to the Internet, even with an Ethernet cable connected (skill issue, I presume). So I tried Gentoo but the installer froze. Desperate, I installed Debian Bookworm and everything worked on the first try… such a pity that they don't support 32bit architecture anymore!

My quest for a modern OS for my 2005 computer is not finished. Maybe I'll try Parabola next.

@emmanuelwald @socksinspace @birdgoose I am planning to install OpenBSD on a little machine in my closet for network services, but I have been really curious about trying Haiku on my old (2003) Dell laptop.

@ameredith Haiku is great! To be honest I don't think I already used it on bare metal, but I always have a VM with Haiku, which I use when I need variety. I have to relearn the shortcuts every time, but when I know them, it's a different yet pleasant workflow.

And it's thanks to Haiku that I discovered one of my most used tools: groff.

@emmanuelwald I haven't used it before, but it was recommended to me, and from what I hear, it's one of the best options for 32-bit hardware
@ameredith it is, but Haiku is a GUI centered OS. For my project, I need something which work without a display server. I want an “e-typewriter” to write with the less possible distractions. I love Haiku, but it's as full of distractions as any normal OS.
