BIOS and controller dumps for an Avell B153 notebook, which is built on the Compal LA-7871P motherboard, with images marked for positions U59 and U60. Avell resells ODM chassis, so the Compal board number is the key reference rather than the retail model. Open the archive, match each file to its chip location, and program it with a CH341A or similar SPI programmer. Always read and store the existing contents first and confirm that the dump length fits the flash chip fitted on your board.
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.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
