Firmware dump for the HP Compaq 8100 desktop, built on an MSI-manufactured board MS-7557 revision 1.0, compressed in a 2.64 MB RAR. MSI uses the MS-xxxx code for its motherboards, including OEM designs it supplies to HP business PCs. A technician would program this image onto the board's SPI flash with a clip and programmer to recover a failed update or corrupted BIOS. Match the MS-7557 silkscreen and revision on the PCB, keep a backup of the original chip, and note that serial and system data may need to be restored afterwards.
