I had a POST failure Dell 3050 micro system and a good one. The failure code is 25 (2  amber + 5 white) indicate a corrupted bios. Since there is no display so I can't enter in BIOS/recovery screen to force flash the bios. It seemed only way to flash with external programmer.

Now my question is:  since Dell won't provide raw bios file then my idea is use another good system's bios backup to flash into faulty system bios, does that work? or there is something unique per machine that we can't simply overwrite?

Any suggestion?
