BIOS dump for the MSI B150M-Bazooka motherboard, sized for an 8 MB (64 Mbit) SPI flash chip according to the name. The archive is 5.06 MB compressed, and the extracted image should be exactly 8 MB to fit the chip. Technicians use a full dump like this to recover a board with a corrupted or failed BIOS by programming the chip directly with a CH341A, RT809 or similar. Read and save the original contents before erasing, confirm the chip part number, and verify the write before refitting it.
