Fujitsu Lifebook A573G BIOS package for the board labelled CP631522-X2, containing 1MB and 4MB images in a 2.88 MB RAR archive. The two sizes indicate the firmware is split across two SPI flash chips of those capacities. Each image must be written to the chip of matching size using a programmer, otherwise it will not fit or the board will not boot. Read and save both original chips before any writing, and verify the CP number on the PCB against this file.
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.
