after power up , and yes i have a 10 amp powrr supply , i always get the following screen :
EFI SHELL VERSION 2.70 [5.13]
Current running mode 1.1.2
cannot find required map name
Shell> _
?? i cannot boot with a usb drive because my usb drive , with windows 11 , says my kernel is defective…also i tried with the recovery button sequence and that gets me nowhere too. I have removed ssd and board is naked except power , keyboard.
