Hello, looking for the bios Acer Aspire 5820TG, I mean the entire contents of 4MB of memory, because memory is burned, and the charge is 2MB, so I need the whole shot, because from what I learned the bios is written from the second half of the memory, and here the question arises as to whether the memory clean throw charge, and the first half will be pure, if the laptop will work, but does it have to be there too the original data, and what in general is the first part, the memory is W25q32vbsig Winbond. p.s. I apologize for my poor English.
