fuzzylogic Posted November 11, 2020 Share Posted November 11, 2020 Having used Open core since early creation there doesnt appear to be any joined up thinking with regard to motherboard chipsets (it has been lost or not updated). I use the 390 chipset and look at some of the new Apic additions and wonder what they mean. I am confused as to why upgrading from 0.6.3 to 0.6.4 results in the loss of picker, yes even set built in or external and messages about Tools even though tools are there and selected. core changes between 0.6.3 and 0.6.4 shouldnt amount to reams of information where users may get lost for example why not put if your using this chipset these issues are critical to your boot process. I do not know what I have done to end up in a no boot situation, luckily i have a usb drive and can boot from that. I have tried both Builtin and External but instead it goes to the Tools menu and ignores the picker Config.plist Link to comment Share on other sites More sharing options...
