Original dump for the Dell Latitude E5440, read from chip U2, a Winbond 25Q32FV 32 Mbit SPI flash. The E5440 uses two BIOS chips, and this archive covers only the U2 position, so a matching U1 image is required for a complete restore. Extract the RAR and confirm the binary is 4 MB to fit the chip. Read the current chip before writing, then program and verify it with a hardware programmer, keeping the two positions apart.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
