Firmware dump for a ZX-H61C desktop motherboard, with B75 and version V3.41 noted in the name; the exact relationship between the H61 model name and the B75 marking is not explained. The image is listed as 4MB, so it suits a 32Mbit SPI flash chip, and the archive is a 2.55 MB RAR. Use it to reprogram a corrupted BIOS chip with an external programmer. Verify that the board marking matches, back up the original contents first, and check the image size against the chip before writing.
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.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
