I left my Blahaj, my librebooted Thinkpad X230, and a pair of thigh-high socks in a pile unattended on the night of a full moon and when I returned the HS3 had appeared. I’m not sure if Ikea sells them or not but it may be worthwhile to ask an employee at one of their fine stores if this is the case.
As previously stated, this thing simply appeared when I wasn’t present, but if I had the files, they’d be at https://gitlab.com/4096kb/ps3hajcoldboot/ 👍
