Acer Aspire 4810tg JM51 DIS (48.4CR05.021)

BIOS .rar 3.41 MB Shared

Firmware archive for the Acer Aspire 4810TG, project JM51, discrete-graphics version as marked DIS, with board part number 48.4CR05.021, in a 3.41 MB RAR. The 48.4xxxx.xxx form is the style Wistron uses for Acer board part numbers. Check the PCB number and the discrete GPU before use, since UMA and DIS boards need different images. Use it to reflash the BIOS chip with a programmer to cure no-boot faults, after saving the original contents.
