From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

It's 2023. By this time I'm fine if BIOS boot was removed completely.
Not really related to what Red Hat is doing with their OS.
"many public cloud vendors also default to BIOS booting of their VM instances"
So it's about cloud VMs.
Are there any machines in use anymore that don't support UEFI? When did it become standard? Something like 2012?
At my company, we have around 400,000 servers in production. When we last surveyed them, we found several thousand over 12 years old, with the oldest at 17 years. And that wasn’t counting our lab and admin servers which could run even older because they’re often repurposed from prod decomms.
We had a huge internal effort to virtualize their loads, but in the end, only about 15% were transferred just due to the sheer number of hidden edge cases that kept turning up.
How many of them would ever run an OS released in 2023?
All of them. Corp directive (now) is that hosts must be updated or reimaged every 90 days.
2014 is when a majority of new systems were UEFI, according to Wikipedia, but that's still a majority.
Intel announced in 2017 that by 2020 they're no longer gonna include BIOS support in their computers. So it could easily still pop up today, although it's not that likely to, since that support is for devices that can use either BIOS or UEFI.
As the article explains, the move is about VMs but IMO it would make more sense to improve UEFI support in VM solutions than this.
I have a bunch of Intel motherboards circa 2015 that "support" UEFI as in it will boot windows but not any other payload.
If the replacement is Coreboot thats OK, but if this is UEFI no thank you !
