BIOS .bin_statusregval 2 B Shared

Two-byte status register value file accompanying the second betty 2540 dump, generated by flash programmer software during chip reading. It records the SPI flash status register, including block protection bits, and contains no executable firmware. Technicians can use it to see whether the chip was write-protected, which explains failed erase or write attempts. Do not try to program it as a BIOS image; use the matching 8 MB binary instead. The name suggests an HP 2540-class laptop but gives no board number or revision.

The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosfilebins. Enginerys does not host this file.

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