I have been toiling with this for the greater part of the week and I brought the ofwboot64 code up to 6.8 status (without the FDT). I have made some announcement here: https://centroid.eu/ppc/#20201218 . I have some sysadmin tasks to do at home which will take me into January and then I'll work on putting a flattened device tree into this loader. However I'm already dreaming in the clouds (could be a detriment), I wonder if this work pays off and it works if I can get a IBM BladeCenter H with these JS21 Blades for it. I wonder if they are compatible and utilize openfirmware in a way that ofwboot can be used. If so that's really cool as a build-farm for ports or something could be built with these (each unit would have 16 GB RAM). I found this on ebay... http://vi.raptor.ebaydesc.com/ws/eBayISAPI.dll?ViewItemDescV4&item=131558745375&category=11211&pm=1&ds=0&t=1598358778000&ver=0 The possibility of getting such old hardware is exciting... So anyhow back to coding in 2021...have a merry season all it's been a good year! -peter
