Second copy of an Acer Aspire 5920 MB6G0 BIOS dump, 1.00 MB binary; the (1) suffix usually marks a duplicate saved under the same name. Compare it byte for byte with the other MB6G0 file to see whether the contents actually differ. The size matches an 8 Mbit flash chip, programmed with an external SPI tool for recovery after corrupted firmware. Verify the MB6G0 identifier and board number on your machine, and read out the original chip contents first so you can roll back.
