I’ve been wanting to test Haiku OS on an Intel Xeon processor for a while. And recently I had my chance after having access to a Dell PowerEdge R620 that was pulled from production.
So I used a downloaded copy of Haiku OS nightly build from 8/20/2019.
You can see the short blog and pictures here: https://davidf215.blogspot.com/2019/08/testing-haiku-os-on-dell-poweredge-r620.html.
Long and short: it ran and recognized all 12 cores but didn’t see the SAS drives.
