When you installed Linux on a Windows computer? I wiped Windows, but the firmware data is still there: # cat /sys/firmware/acpi/tables/MSDM MSDMU:_ASUS_Notebook ASUSXXXX-KKKKK-KKKK-KKKKK-KKKKK# (License string obfuscated.) 'strings' not required. Fascinating: thank you Stewart, this may make it possible to install Windows 10 in VirtualBox - of course I still have to lay hands on a matching version of Windows, although those are easier to find than legitimate license keys. Hmm - I wonder if the "ASUS" at the beginning of the key means it only works with Asus versions of W10 ... -- Giles https://www.gilesorr.com/ gilesorr@gmail.com

My current maching, a Dell laptop, does not have that file.

Well I know my Dell desktop at work runing linux has that file. My home built desktop with an asus board in it, does not (no surprise there). I haven't checked my laptops but I suspect they all have it. -- Len Sorensen

Is it perhaps a license for installed firmware? I have that file on an HP/Compaq laptop, in a fresh Debian install to a brand-new SSD. We had to install some non-free firmware to get the laptop to boot. It was all done in a spirit of hasty improvisation, so I don't remember which firmware it was. Way back when, the laptop was delivered with Windows 10, which I blew away on the original HD. The license number for that is on a sticker on the bottom, and it's a different license number from the one in the MSDM file.

Sorry for the misinformation: the non-free firmware was needed to get Wifi to work. (It was a Debian netinstall, so I guess my mind conflated that with booting.)

(It was a Debian netinstall, so I guess my mind conflated that | with booting.) There is firmware for UEFI and ACPI and SMM and all those things. This is almost always in "ROM". (It isn't strictly ROM since it can by updated by flashing new firmware.) (I suspect it is in a serial-access eePROM (SPI) and gets loaded into RAM as part of power-on reset.) Firmware blobs for device drivers are typically loaded by the OS from disk files. Those two kinds of firmware a logistically quite different. Essentially no firmware for booting comes from a disk. UEFI booting can run UEFI binaries (.efi) from /boot. That may include diagnostic programs or a UEFI shell. | > Znoteer wrote: | >> On Tue, Apr 13, 2021 at 07:42:47PM -0400, Stewart Russell via talk | >> wrote: | >>> If the file /sys/firmware/acpi/tables/MSDM exists (it's read-only to | >>> root), | >>> there's probably a key embedded in there you can pull out with strings | >>> | >> | >> I don't seem to have that file, and I'm not surprised.

Here's my current understanding: If you bought hardware with bundled Windows, from a major manufacturer, in the last few years, it should be there. If you bought a system, with OEM Windows, assembled from bits by a smaller vendor, the a Windows product key should not be there. You should have been given a product key on a "certificate" printed on cardstock. If you bought a system (or motherboard) with no bundled Windows, I would expect the product key would be missing. | > Is it perhaps a license for installed firmware?

My HP desktop from 2013 has the "file". /sys/firmware/acpi/tables/MSDM is in the /sys filesystem which has all sorts of things made to act like files, but they are not on a disk.

Maybe your motherboard BIOS came with a Windows licence? I don't know all the ways it can get embedded there. Either way, if you start the installation, it'll never ask you for a key and you'll find everything's authorized automatically. Some machines (like this HP laptop) have very obvious OEM licenses (the string "OEM" shows up several times in the BIOS record) that probably wouldn't transfer well to VirtualBox, etc. cheers, Stewart

I don't have it on my Thinkpad. But then, it doesn't have the original drive.
Mine is a thinkpad, too (x240), that I'm pretty sure probably started life with windows on it (I bought used so I'm not sure), but the file is not there, so it's not a sure thing. In the end, I guess I'm not disappointed, because I don't really have a use for Windows anyway. -- Znoteer znoteer@mailbox.org

Mine came with Windows 7, since updated to W10 and it's dual boot Linux & Windows. I do have some need for Windows, including my Garmin GPS which has a Windows app to update it and a TP-Link managed switch, which has a configuration app that runs on Windows. I have also had some work related reasons for needing Windows. One very important thing I did was to cover the Windows key with a Tux sticker that nicely fits in the depression on that key. ;-)

I'm just too busy so I'm sending it without completing it] | If the file /sys/firmware/acpi/tables/MSDM exists (it's read-only to root), | there's probably a key embedded in there you can pull out with strings I knew it was in there somewhere, but I didn't know where. Over the years, Microsoft has changed how they distributed OEM keys. For a long time, it was on a fancy sticker on the computer itself (holograms etc.). There were separate stickers for other bundled MS products like MS Works and MS Office. (I had a system where the sticker was in a little pull-out tray.) Eventually, they put the Windows product key in the "BIOS" (firmware). For a while, I think that they still put the sticker on the box. Datapoints: - my 2013 desktop came with Windows (8.0?) has the embedded key - my 2020 Precision 3440 SFF came with Ubuntu (no Windows license) and does not have that file - my Dell Inspiron 530 (BIOS date 2009; Core 2 Duo E6550) came bundled with Windows and doesn't have that file, at least under CentOS 6. - Chris Johnson's Dell laptop came bundled with Windows but does not have the embedded key. I assume that the file is missing. Unknown: the vintage of the laptop Unknown: There was a limited time where you could update pre Win 10 systems to Win 10 without buying a new license. If you did that, Microsoft recorded this fact in their central system. That period is over. What happens now if you take a pre Win 10 system, with a firmware OS key, and install Win 10? Does it work? My superstitious belief is that it does, even though it isn't MS's stated policy.

No, it's not. Windows will no longer deliver the upgrade tool via automatic update, but you can download it here — https://www.microsoft.com/en-us/software-download/windows10ISO — via the *Create Windows 10 Media Installation* tool. It will definitely upgrade Windows 8 (as that's what would install on my laptop) and may do Windows 7 too. This means I bought an unnecessary (by anyone's definition) Windows 10 Pro licence. It wasn't as cheap as Evan's copy (it's from a more-legit source), but it was still about $60. Quite a lot for one line of text ... Stewart
