No, there is no way to legacy boot at all, I cannot boot to DOS. No CD, no USB-HDD or LAN. Only EFI Boot option presents that fails, this time it says about wrong keys Is it any chance to restore the BIOS (OK, let it be RESET version without SLIC, damn Secure Boot tortured me )? May be try something like preparing the AMIBOOT.ROM and use Boot Block if it is present there? View attachment 33380 No options Tried to insert good old Win9x CD - it does not budge. I found the way to enter boot block and ASUS EZ Flash built-in utility. Can we try to flash something working? I need an image (ROM file) in the form of the BIOS file, not the pieces for patching... What can I try to flash?
