Second copy of the 8 MB 430 G1 BIOS dump, probably read twice to verify consistency. Matching checksums between the two reads give confidence that the clip had good contact and the data is intact. The file fits a 64 Mbit SPI chip and can be written back with a CH341A-class or similar programmer for recovery. Take a fresh backup of the target board's chip first. Note that unit-specific data such as serial number may be carried over from the source machine.
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 @biosfilebins. 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 →
