Hello, Being new here, I hope I'm posting in the right place. I'm looking for an old version for my Acer Aspire Timeline 4810T model. Insyde Bios. Version 1.23 is what I'm so needing. Stupid me I upgraded to latest in hope for a backlight-problem to disappear, but it turned out worse. I then downgraded to v. 1.20 - can't decide if it's running okay or not. Could someone perhaps have an original unmodified version of 1.23?
