Original BIOS dump for board LA-A993P revision 2.0, with the platform code ZS040, in a 3.96 MB RAR. Compal uses the LA-xxxxP format, and the ZS040 tag is the platform name printed on the PCB next to it. Because the dump is marked original, it is likely a full read from a working chip, which may include machine-specific data such as serial numbers. Check the revision on your board, back up the existing chip, and confirm the image size matches the flash before writing with an SPI programmer.
