First volume of the BIOS Acer multi-part RAR archive, 9.00 MB. Extraction starts from this part, but the following volumes must sit in the same folder for WinRAR or 7-Zip to rebuild the full collection. Only the brand is stated, so models and board numbers inside are unknown until unpacked. Use any image only after confirming the motherboard number and revision match the PCB, backing up the existing SPI flash, and checking the dump size fits the chip.
