Blessing Fog server doesn't work on Macmini7,1

pulling the Wi-Fi card from all computers isn’t necessarily a viable option.

It can likely be scripted to use ethernet first, also.

@Wayne-Workman It was booting to ipxe.efi fine; the issue was that once ipxe.efi loaded it didn’t work right.

@Tom-Elliott snponly.efi worked on a Mini with the wifi card still in. It showed the same error message (with DUView.c and AppleBootUI.c) that net1 showed in ipxe.efi, but it tried net0 first instead of net1 and successfully loaded the menu.

Once it reached the menu, “Boot from hard drive” failed with a “chainloading failed” message. Should I use this thread for that question or start a new one?

@cpast Change the registered host’s “exit” type. You can do this globally too.

Exit doesn’t know how to release properly and sanboot is the “default” but sanboot uses the “legacy” machinisms. YOu can try setting exit for efi exit type though.

[cpast]

@Tom-Elliott Setting “EFI Exit Type” to “EXIT” (in the host settings, in global settings, and in group settings) didn’t work. Also, I noticed an issue with the snponly.efi solution: trying to deploy an image results in nothing happening after it says “bzImage loaded” and “init.xy” (it just stays on that screen).

[Tom Elliott]

@cpast So using snponly.efi wasn’t expected to work, just was hoping to see if it would try the wifi address.

If exit type isn’t working (and obviously sanboot isn’t) then I think the only option left for mac’s is to use the rEFInd exit type (though you may need to edit the config for yourself as I don’t know it’s inner workings yet.)

[cpast]

@Tom-Elliott rEFInd works (I just had to set it using the web interface). However, if snp.efi and snponly.efi don’t work, I’m back where I started with it not working without the wifi card pulled.

[Tom Elliott]

@cpast You tried both? What about specifying intel or realtek? I don’t know what type apple uses.

[cpast]

@Tom-Elliott I tried both snp and snponly and neither supported a deploy operation. The Mac Mini uses Broadcom, so I tried building a tg3.efi iPXE, and that seems to be working. If other Macs don’t use a tg3.efi driver, is there a way to build multiple drivers into one EFI that’s not ipxe.efi?

[Tom Elliott]

@cpast if you built tg3.efi, you can build intel, realtek, etc… just by choosing to do so when building.

@Tom-Elliott I looked through the rom-o-matic for the iPXE kernels and I didn’t specifically see a tc3 or tigon3 card called out specifically. BUT, if you can use a specific iPXE kernel with only the driver for the tigon broadcom network interface, you may luck out and the wireless adapter may not be seen at all by the iPXE kernel as it would if you use one of the general purpose efi kernels.

Once you can narrow it down to a specific ipxe kernel that will only see the ethernet adapter then we have options for us to use. If you dhcp server is isc-dhcp (linux), dnsmasq (linux) or windows 2012 dhcp we can create a custom filter to only send the tc3.efi kernel name to the booting efi device when a MAC is detected. That part is a bit more complex but it is possible and we can make it all automatic, but the key is finding an iPXE efi kernel that only sees the broadcom network adapter.

Could you be a bit more specific on which exact model you are having those issues on. AFAIK there are at least four different models called ‘Macmini7,1’ - possibly more:

As well it would be great if you could give us the vendor and product ID of those ethernet and wireless cards build into your Macminis…!

@cpast : Were you able to fix netboot?
