And for all the crap Lenovo laptops are these days; they also have backup BIOS.
Funnily enough, most BIOS updates end with a "self-healing backup progressing" screen nowadays - which makes me wonder: do they overwrite the backup and abuse that mechanism to update the primary bios?

A fallback BIOS should be standard by now
Didn't Gigabyte put that onto their mainboards
Yes, around 2009: https://www.techpowerup.com/96967/dualbios-becomes-standard-...
Gigabyte has had dual bios motherboards since 1999, but made it standard for all their motherboards in 2009.

As I recall, they initially introduced this feature due to a virus around the time which would intentionally corrupt BIOSes.
The CIH virus? https://en.wikipedia.org/wiki/CIH_(computer_virus)
And any server has them.
