8.00 MB binary named after the Macronix MX25U6435E flash, with a 1.8V note. The MX25U6435E is a 64 Mbit low-voltage SPI chip, which matches the 8 MB size. No device or board is named, so the dump's origin is unknown and it should only be written after confirming it suits your board. Because the chip runs at 1.8 V, use a programmer with a 1.8 V adapter; feeding 3.3 V can damage it. Back up the original contents before flashing.
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 @vinafix_bios. Enginerys does not host this file.
