An Embedded Linux on a Single Floppy

I wonder why the 486 DX is supported but not the SX. How is the math coprocessing unit necessary for kernel and basic system tools?

The distro would have to include FP emulation software for the 486 SX, which is a big chunk of code if a floppy disk is all you have to work with.

Also, some system tools need FP support (like df).

exactly that: too complicated.

also I got 486 DX2/66 as my first PC so I set that as a goal. Then checked how lower can I go. Also I only have 486 DX4 now to test on real hardware.

as far i remembered SX emulation adds 37kb to the kernel
