Raw 4 MB ROM image whose name states only the capacity plus an A24 tag, with no model or board identified. It likely pairs with an 8 MB companion on boards that split firmware across two SPI chips, but that cannot be confirmed from the name. The file fits a 4 MB (32 Mbit) flash device and is written with an external programmer. Before flashing, read and save the existing chip and verify that the image matches the target board, since an unrelated dump will leave the machine unbootable.
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 @CLRINDORE. Enginerys does not host this file.
