Working BIOS dump for the HP Compaq dc5750 desktop, built on the M2RS485-BTX board with the .106 tag from the name, packed into a RAR archive of about 1015 KB. The working label means the image was reported to boot on real hardware. Technicians write such a file to the motherboard SPI flash with a programmer like the CH341A when the original firmware is corrupted. Read and save the existing chip contents first, and confirm the image size equals the chip capacity so the write completes without a mismatch.
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.
