You need to read full dump of BIOS by a suitable hardware programmer.
Then modify it by CoffeeTime and flash it.

dumped with ch341a but coffeetime doesn't read the file: "corupt or unknown"
any help?

It didn't work.
Now i've got 2 units bricked
I'll try to revert the old, original bios..
Both looks the same when try to boot (after power up): no video output,
No vga or hdmi, no keyboard react.
1 unit cpu fan come on and off, 1 sec on 1sec off, bootloop like.
2nd one cpu fan stays on all the tim.
