The documentation of this function (http://wiki.phoenix.com/wiki/index.php/EFI_BOOT_SERVICES#ExitBootServices.28.29) states that the mapKey is wrong and GetMemoryMap() should be recall and then ExitBootServices() again. I've tried to implement it, but it fails again. My main problem is that I don't know which parameter should I pass to GetMemoryMap() I gave a look to this discussion (http://www.gossamer-threads.com/lists/linux/kernel/1733014) about "retry ExitBootServices() on failure" about eboot in Linux: they do a retry (only one) and they call also a FreePoll(). Do you have any tips, suggestions or something that could help to get FreeBSD boot on this apparently standard board? Best regards, Luca Pizzamiglio PS: should we implement the ExitBootServices() retry?
