4 MB raw BIOS image for the HP 630 with the HM55 chipset, marked BIG, meaning the larger of the two SPI flash chips used on this platform. A 4 MB file suits a 32 Mbit chip that usually holds the main BIOS together with the Intel ME and descriptor regions. Pair it with the matching SMALL image when restoring a board with corrupted firmware. Verify the chip capacity and board revision, dump the original chip before erasing, and use an SPI programmer that supports the installed flash part.
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.
