Hello Acer Aspire ONE D257 I have extracted the BIOS with 7-zip and it gave me a folder with many files and one .fd file which is 2048 KB in size. What I want is to write the bios using an eprom. So, is the .fd file enough to write on the BIOS chip or would I need a ROM file. If I need a ROM file, how to get it? Thanx. P.S. cant post links.
