Description
BIOS dump for Lenovo laptops, supplied as a ZIP archive of about 16.7 MB. The original file name points to the ThinkPad X1 Yoga 5th Gen (Type 20UB / 20UC) and ThinkPad X1 Carbon 8th Gen (GX4A0 / GYG50) family, but the facts do not confirm which machines this exact dump covers, so check the model and BIOS version against your unit. Technicians use a dump like this to reprogram the SPI flash chip with a programmer after a corrupted BIOS or a failed update.
