Lenovo and Microsoft came under fire this week when a Reddit user named BaronHK reported that he was not able to install Linux on Signature Edition Lenovo Yoga 900 ISK2 UltraBook.\n\n\nBaronHK wrote:\n\n\n\nThis is related to the ongoing discussion in Lenovo's forum's about why the SSD is locked in a proprietary RAID mode that Linux doesn't understand. Laptops known to be affected include the Yoga 900 ISK2, Yoga 900S, and Yoga 710S, which all have the same issue according to posts I've read on Lenovo's Linux forum.\n\n\n\nBaronHK also wrote a 1-star review for the laptop on Best Buy. The issue got even more complicated when someone claiming to be \u2018Lenovo Product Expert\u2019 commented on the review and wrote: \u201cThis system has a Signature Edition of Windows 10 Home installed. It is locked per our agreement with Microsoft.\u201d\n\n\nMany Linux users, and some news outlets, were quick to jump to conclusions and criticized Microsoft. I reached out to Lenovo and their spokesperson dismissed the allegation as incorrect that Lenovo and Microsoft have an agreement to \u201clock\u201d the UEFI bios on Microsoft Signature Edition systems to prevent installation of other operating systems.\n\n\nWhen I asked whether Lenovo is restricting customers from installing any OS of their choice, the spokesperson said:\n\n\n\nTo improve system performance, Lenovo is leading an industry trend of adopting RAID on the SSDs in certain product configurations. Lenovo does not intentionally block customers using other operating systems on its devices and is fully committed to providing Linux certifications and installation guidance on a wide range of products.\n\n\n\nLenovo in fact maintains a very comprehensive list of products that are fully certified and supported on Linux. Yoga 900 is designed for Windows 10 and is not on Lenovo\u2019s Linux supported list.\n\n\nLenovo spokesperson said that such unsupported models will rely on Linux operating system vendors releasing new kernel and drivers to support features such as RAID on SSD.\n\n\nBut the interesting fact is Linux already supports RAID on SSD. It\u2019s been there for ever. We reached out to Greg Kroah-Hartman, one of the leading kernel developers, and he said, \u201cWe support more raid controllers than any other operating system, and we support software raid as well (recommended over hardware raid as it doesn't lock you into any one host controller vendor.)\u201d\n\n\nCommenting on the whole saga, Kroah-Hartman said \u201cIt's just a \u2018look, another odd storage controller that Linux might not support, but no one really knows as they don't have the hardware to test it with\u2026\u2019 issue."\n\n\nHe suggested that someone who wants to investigate the problem should actually get the laptop under question and work on it to see what the issue really is.\n\n\n\u201cOdds are it's just a matter of configuration of the storage controller options in the BIOS and picking the correct Linux kernel storage controller driver for it. If it's a whole new controller driver that we need to write, great, we can do it if that's needed and someone provides the specs for it (that's what the Linux Driver Project does all the time.),\u201d said Kroah-Hartman.\n\n\nThe takeaway is: no, neither Microsoft, nor Lenovo are deliberately locking Linux users out of their laptops. It\u2019s just a matter of figuring out what\u2019s wrong. And that\u2019s something Linux community is very good at. Instead of vilifying companies, we should investigate the problem and try to fix it.\n\n\nIt\u2019s actually a good story. I recall my very early days with Linux, when it would be newsworthy if you were fortunate enough to come across a laptop that worked with Linux, out of the box. Times have changed. Nowadays, if you come across one random laptop that doesn\u2019t work with Linux, it becomes news.\n\n\n\u201cWe have come a long way :)\u201d said Kroah-Hartman.
