Linux on a 486SX

I've spent the past several months trying on and off to make Linux run on the Presario. The 486SX is the oldest CPU Linux still supports! I was quite hindered by my lack of any floppy disks - fortunately, I managed to get my hands on a few working ones for Christmas this year and made some headway, first getting MS-DOS 6.22 installed on the new hard disk, then messing with the Linux kernel configuration until I got it to work.

And yesterday I finally got it! Here are the steps for configuring a basic kernel with Linux 5.14.8.

A lack of usefulness should not be a hindrance to having fun.
