Use it (log in first)All online tools
What it fixes
- A Dell BIOS is damaged and needs vendor data
- You only want the BIOS / ME / EC regions out of a vendor package
How to use
- Log in → Online tools → choose “Dell BIOS merge and unlock”
- Merge: upload the vendor package together with the original dump (both chips separately on dual-chip boards)
- Extract only: upload just the vendor package
- Download the result: merging gives several variants; if the first does not boot, try the next
What you need
Vendor BIOS (.bin or the official .exe); the original BIOS dump
Note：Extract-only output is region slices that cannot be flashed directly; merge them with the original BIOS. Dual-chip boards get chip 1, chip 2 and the combined BIOS (for analysis only).
