Lenovo created a stir when it said the Yoga 900 and 900S hybrids would work only with Windows, not Linux. The company has now changed its stance, bringing Linux support to those PCs.
The PC maker earlier this month issued a BIOS update so Linux can be loaded on Yoga 900, 900S and IdeaPad 710 models.
The BIOS update adds an AHCI (Advance Host Controller Interface) SATA controller mode so users can load Linux on the laptops.
This is a Linux-only BIOS, meaning it should be used only by those who want to load the OS. If you want to continue with Windows, do not load the firmware. “This BIOS is not intended to be used on machines running Windows operating systems,” Lenovo said.
Still not an ideal solution, but at least they’re listening.
I’m guessing/hoping that this update just undoes Lenovo’s 2 byte patch responsible for hard coding the AHCI bios option. I doubt they would go further and make new changes just to break windows.
The message probably got lost in translation: “unnecessary for windows” -> “only use if running linux”.
