I have a Handheld PC ,DT Research DT311.It has no passwords or something.I have changed boot options from bios from uefi to legacy,and after reboot it stays at blank screen no light no blink only fanspin.It can be powered off from power button with longpress.I do not have acces to bios files from support.Instead I have the bios dump from ic which I attach here.Here comes the question: can it be resetted to defaults?I have H2Oeze but I have no experience with it.
