If you are running an i486 CPU, you will want to read this.

The Linux Kernel is Finally Letting Go of i486 CPU Support

The support remained in the Linux kernel all these years after every other major platform dropped it.

It's FOSS
This means that support for true 386s is gone as well, doesn't it?

I maintain both a 64-bit #Linux #distro and a 32-bit version because the latter is nearly as easy as just doing multilibs [which is what #Debian and some other distros do].

But my 32-bit distro won't boot on genuine 386 PCs even now, before kernel 7.1 arrives, will it?

Retired my last i486 in 2016.

Or: it kind of retired itself...

Bought in 1998 from a friend who bought it new in 1996, replaced win95 (or 98) that was on it when I bought it, with SuSE linux.

When SuSE failed to update it ran for a while using floppyfw (created by a friend of mine)

In 2001, I put a debian netinstall floppy into the floppy disk drive and installed debian and ran "apt dist-upgrade" from 2001 to 2016 when the HW finally failed.

@itsfoss In the worst case, I think some BSD flavours are still supporting it in a way or another; at least nominally NetBSD has it as minimal requirement.
NetBSD even support Amiga48k...!

NetBSD/i386 Supported Hardware

@raster @itsfoss LTS versions of Linux will keep supporting it for a few years.
@itsfoss cmon Linux keep support
@itsfoss I'll light a cyno today. That was the first CPU I learned.
