Linux bids farewell to support for the outdated 486 chip
- The Linux kernel will cease support for 486 CPUs, as stated by Linus Torvalds.
- The last manufacture of 486 chips occurred 18 years ago.
- This marks a significant shift to focus on modern technology and improve the kernel's performance.
In 2022, Linus Torvalds suggested that Linux should discontinue support for the 486 CPU, which has not been manufactured since 2007. It marked a significant transition as the Linux kernel had already removed support for the i386 architecture a decade earlier, in 2012. As of now, it has been 36 years since the release of the 486 chip, and 18 years since Intel ceased production. The Linux development community believes this elimination of antiquated support will enhance the performance of the Linux kernel, allowing it to utilize newer features that the 486 lacks. Furthermore, the decision reflects a broader trend in the tech industry towards prioritizing advancements over legacy systems, as unmaintained older technology can weigh down progress. While this decision may concern some users still operating 486 systems, they are encouraged to use older distributions and kernels that remain compatible with the architecture. Options like FreeDOS, as well as modified versions of Windows XP, could provide functionality for those committed to utilizing these vintage systems. However, users are advised against connecting these older machines to the internet due to security vulnerabilities. Support for the 486 chip had been maintained longer than anticipated, given the extended time since its last manufacture; many in the development community had likely underestimated the number of users who still operated these systems. Ultimately, with Linus Torvalds citing a lack of practical reasons for 486 support, the Linux kernel aims to improve by embracing modern capabilities while still acknowledging the legacy of past technology and its users. In conclusion, while it evokes nostalgia for many tech enthusiasts, the decision to end 486 support symbolizes a forward march in technology, leaving behind outdated hardware on which contemporary system software cannot effectively operate. Users running on this architecture should now look for legacy-compatible solutions or consider upgrading to modern hardware.
