What it fixes

- “Universal BIOS extract” gave an update package / slice that cannot be flashed directly
How to use
- Log in → Online tools → choose “Universal BIOS merge”
- File 1: the full original dump (both chips separately on dual-chip boards); file 2: BIOS data extracted from the vendor package or a dump of an identical board
- Choose the mode: full block (usually HP) / safe (usually Dell) / smart; tick NVRAM or Padding merge if needed
- Download the merged BIOS and write it back
What you need
The full original dump (.bin / .rom); extracted vendor BIOS data (.bin / .rom) or a dump of the same model
Note：.exe files are not accepted; use “Universal BIOS extract” first. NVRAM usually holds settings and may hold the serial number; EC data is usually in the padding area.
