BIOS dumps for the Dell QAR00 board, Compal LA-7931P revision 1.0, supplied as 4 MB and 8 MB images. The two sizes suggest the firmware is split across two SPI chips, a common Dell arrangement, so each image must go to the chip of matching capacity. This board is used in the Dell Precision M4700, and the LA-xxxxP number is Compal numbering. Read and save both original chips before writing with a programmer, since they hold the service tag and system data. Check the board number and revision 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 @biosarchive. Enginerys does not host this file.
