AU B141EW04 V4

BIOS .bin 128 B Shared

Second variant of the EDID for the AU Optronics B141EW04 revision V4, a 128-byte binary for a 14.1-inch notebook panel. The data is a single base block containing the vendor code, product number and timing descriptors used by the graphics controller. Technicians use it to rebuild a corrupted panel EEPROM or cross-check other dumps of the same part, since copies may differ in serial or date fields. Validate the checksum in an EDID tool, match the revision printed on the panel and read out the chip before writing.

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 @biosarchive. Enginerys does not host this file.
