Dell OptiPlex 755 Bios Update - Skips rows in BIOS and double characters when booting into DOS
I updated from A19 to A22 and even back down to A19 on my OptiPlex 755... Now it skips lines when I try to change settings in BIOS or when I boot to a DOS USB drive it double types letters. Never happened before until after this update. I ran into this a few years ago and I know its a simple fix, but I can't seem to remember what I did. It does not happen in Windows 7. I've swapped the keyboard, etc.
