BIOS package for the HP Compaq 6200 business desktop, with the motherboard named Bach, revision A. The zip is 5.01 MB, and its contents should be checked to see whether it holds a raw SPI dump or a vendor image. A raw dump is written directly to the flash chip with a programmer when the system is bricked or will not POST. Compare the image size with the capacity of the onboard chip, and back up the existing contents, which may hold serial and product data, before erasing.
