post the original bios,model and serial number

That's the issue, the previous person had clearly tried to flash the efi, as I could barely pull a 1mb read, if I had original dump it would be a cake walk.

So essentially I'm stuck, until I find a working efi with correct me reigon

Kind regards

Sorry indeed it was a programmer setting, but

It loads and chimes but is incredibly slow, stuck halfway on the progress bar.

Have done PRAM/NVRAM reset to no avail.
