New Linux Build Allows BIOS Updates Without a Reboot

Phoronix spotted a new Intel open-source project for Linux version 5.17 that allows the operating system to update system firmware, like a motherboard’s UEFI or BIOS, without requiring a system restart. This new  “PFRUT,” or the Platform Firmware Runtime and Telemetry drivers, feature comes as a part of the widely-used ACPI spec, meaning we could see the same approach come to Windows and desktop PCs in the future. 

PFRUT gives systems the advantage of not requiring a system restart when you update the BIOS. This feature will be very useful in server deployments where downtime can hinder business operations. Without the requirement to restart, servers are free to update the system BIOS while ensuring critical workloads remain operational the entire time.
