BIOS image described as working for the Intel DX38BT and DX48BT2 desktop motherboards, packed in a 921 KB RAR archive. Such a dump is used to recover a board with a corrupted BIOS by writing it directly to the SPI flash chip with a programmer like the CH341A. Read and save the original chip contents first, and check that the image size matches the chip capacity, since a mismatched file will not fit. Confirm which of the two board models you have and verify the written data after programming before reassembling.
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.

How to open a .rar 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 →
