Raw BIOS image of 1.00 MB labelled 4930, built on Compal board LA-4201P. The name gives no brand, and 4930 most likely refers to the laptop model, so verify the board number on the PCB before using it. A 1 MB binary fits an 8 Mbit SPI flash chip and is written directly with a programmer such as a CH341A or RT809. Read the original chip twice and compare the copies before erasing, keep that backup safe, and confirm that the chip capacity is 1 MB, otherwise the image will not fit.
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 @afsbiosfree. Enginerys does not host this file.

A raw, byte-for-byte image of a flash chip: the main BIOS / UEFI, the embedded-controller (EC) firmware, or both.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
