Lenovo once again in hot waters over Lenovo Service Engine BIOS
Yuck, is each OS vendor using UEFI as a crutch? I wish the Linux Foundation (or some other group) has advise for chip vendors, IBVs, IHVs, and pre-OS ISVs on how to use Linux properly on UEFI systems. It should require that this Windows-centric BIOS code to NOT be present on a Linux system. What other OS-specific crud is in my closed-source BIOS?!
