4 MB BIOS image named DQ77CP, without extension or further details such as version or ME status. An 8 MB file with the same label also exists, so this may cover the smaller of two flash chips, or a different layout. Read the marking on the SPI chip on your board to confirm its capacity, since an image of the wrong size will not fit. Save the existing contents with a programmer before flashing, and verify the write afterwards to rule out a bad clip connection.
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 @vinafix_bios. Enginerys does not host this file.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
