BIOS file for a Casper notebook identified as CGA C16MB with a VB suffix, in a 2.5 MB 7z archive; the name gives no board number or revision. Casper is a Turkish brand that sources boards from various ODMs, so identify the motherboard by its PCB markings before using this image. Technicians write such dumps to the SPI chip with an external programmer to fix no-boot faults. Read and keep the original chip first, and confirm the image size matches 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 @biosfiles. Enginerys does not host this file.
