Intel's 440BX motherboard chipset was arguably the finest of such specimens to have ever existed. Nothing lasts forever, though, and the upcoming Linux kernel 7.0 is now dropping support for the chipset's EDAC driver (hat tip to Phoronix).
The code hasn't been functional since 2007 due to incompatibilities with the more widely used Intel AGP driver. The lack of EDAC meant that 440BX machines with ECC RAM would still fix errant bit flips, but without software-side notifications. The Intel AGP driver, on the other hand, is used by dozens of older chipsets. Now, 440BX EDAC support has been officially removed, not just disabled.
