BIOS archive for the HP Pavilion dm4-1300 notebook series. Only the model series is stated; there is no board number, revision or version in the name, so verify the motherboard part number and flash chip type yourself. The 1.29 MB RAR opens in WinRAR or 7-Zip. Typical use is reprogramming a corrupted SPI flash with a CH341A-type programmer to bring back a dead or non-booting board. Read the original chip and store that copy before writing, and make sure the image is the same size as the chip.
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.
