A 16.0 MB .bss firmware file titled A32AS315, a size that corresponds to a 128 Mbit SPI flash device. No manufacturer, model or motherboard number is included in the name, so the target hardware must be confirmed independently, perhaps by comparing against the original chip contents. Technicians use such full dumps to reprogram the BIOS chip with an external programmer when a board fails to post. Save a backup of the existing chip before writing and verify the written data after programming.
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 @oficinacomputadores. 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 →
