BIOS and EC-related package for the F550D / X750DP board, revision 2.0, noting an ITE IT8528E embedded controller and a Winbond 25Q32BVSIG flash chip, a 32 Mbit (4 MB) SPI part. The RAR is 2.57 MB. These details tell the technician which chip to clip onto when programming and what image size to expect. Confirm the PCB revision and chip markings match, read and save the original contents first, and do not write an image whose size differs from 4 MB.
