BIOS firmware package for a Compal LA-A992P motherboard, revision 2.0, with ZS050 given in the name as the board's project code. The 7.96 MB RAR archive needs unpacking before the image can be inspected or written. Technicians use such a dump to restore a corrupted SPI flash chip with a hardware programmer such as a CH341A or RT809. Confirm the LA-A992P marking and revision on the PCB, read and save the original chip contents first, and check that the image size matches the flash capacity 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.
