Firmware dump for an X.VISION XDVB-232 device, marked OK in the name and packed in a 6.06 MB RAR archive. No board revision or version is given, so the label is the only identification. Such dumps are typically written to the device's SPI flash memory with a programmer when the unit hangs at boot or no longer starts after a failed update. Before flashing, read the existing chip and keep that copy, check that the image size matches the chip, and confirm the model on the board matches exactly.
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.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
