Mac Pro (late 2013 model) EFI and iPXE booting

[lumps]

For the record, my older Mac Mini has the same "no network found" issue, circa 2011.

I downloaded and compiled https://git.ipxe.org/people/mcb30/ipxe.g.../heads/efi and your code is a much cleaner fix than my hackery.

The code is now failing at line 224 of /interface/efi/efi_init.c

The last 3 lines of the output were:

Code:

EFI configuration table eb9d2d31-2d88-11d3-9a16-0090273fc14d is at 0x7e4ae000
EFI image base address 0x71eba000
EFI could not get loaded image device path protocol: Error 0x7f39e083 (http://ipxe.org/7f39e083)

eb9d2d31-2d88-11d3-9a16-0090273fc14d appears to be EFI_SMBIOS_TABLE (according to http://opensource.apple.com/source/Apple...SMBIOS.cpp) -- I'm assuming that's okay.




UPDATE:

---

I added the following code around line 229:

Code:

        DBGC ( systab, "efirc = %d and rc = %d", (int)efirc, (int)rc);
        DBGC ( systab, "loaded image device path GUID = %s\n", efi_guid_ntoa(&efi_loaded_image_device_path_protocol_guid));
        DBGC ( systab, "loaded image path = %p\n", loaded_image_path);

and the results I got were:

Code:

efirc =3 and rc = -2134499459
loaded image device path GUID = bc62157e-3e33-4fec-9920-2d3b36d750df
loaded image path = 0x0

Looks like RC 3 = RETURN_UNSUPPORTED, right?

So I commented out the "return efirc;" on line 231 and the "DBGC_EFI_DEVPATH ( systab, efi_loaded_image_path );" on line 235 and recompiled.

And it loads iPXE!

But unfortunately, the Mac Pro 2013 network card seems to be unsupported.

The EFI shell command "pci" lists two (2) "Network Controller - Ethernet controller" devices as 14E4-1682 which is the Broadcom NetXtreme BCM57762 Gigabit Ethernet PCIe card (according to this website: http://pci-ids.ucw.cz/read/PC/14e4 )
