Tiny 2-byte status register file saved alongside the betty 2540 BIOS dump, most likely created by programmer software when reading the flash chip. It stores the SPI chip status register value, which reflects write protection bits, rather than any BIOS code. On its own it cannot be flashed as firmware; it is useful only as a record of the chip protection state at the time of reading. The name hints at an HP EliteBook 2540-class machine nicknamed betty, but the model is not stated precisely, so rely on the main image for repairs.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
