Hi Wayne & Frank,
I have read extensively through all the information I could get at the time I investigated that (like 2 years ago), we have macminis, 2011 & 2012. And I never could get them to properly boot on the network, so what I did was to live boot a Ubuntu image on the mac, and “fog” myself (well, that is why I helped have partclone replace partimage in fog, because partimage couldn’t handle hfs).
Now I see you updated the wiki from what I remembered, as I was doing all that in the “pre ipxe” era. So I might give it a try next week… Thanks for the updates, I’ll let you know if that helps.
Cheers,
Gilles
