Status register record of just 2 bytes, created by the programmer for a Winbond W25Q64 read of 15 February 2019. It stores the chip's protection and configuration bits rather than any BIOS code. A technician restores it with the programmer after flashing the corresponding image, or reads it to see whether block protection was set and might block writing. Keep it with its matching 8 MB dump, as on its own it says nothing about the device.
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 →
