BIOS firmware for the HP Compaq Pro 6305 desktop, a 4.26 MB ZIP archive. The name gives no board number or version, so the contents may be a programmer-ready flash dump or an HP update package, which should be checked after extraction. A raw dump is written to the SPI chip with a programmer to revive a system stuck at no POST. Read and save the original chip first, since it can hold serial and system data, and confirm the image size matches the flash 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.
How to open a .zip file
Compressed archive that every operating system opens without extra software.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
