Firmware image for MH330 in .rom format, 1.00 MB, carrying an ON8 tag whose meaning the name does not explain. No brand, board revision or version is stated, so treat the identification with care and compare it with an original read where possible. The size suits an 8 Mbit SPI flash chip. Typical use is reprogramming the chip with a CH341A or similar programmer when the board shows no POST; back up the existing contents first and verify the write.
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 @bios_laptop. Enginerys does not host this file.
