The interlacing on my screen is shot with the upgrade and I have been told that the BIOS is at fault. I have tried a number of ways found in various web sites and have failed on all attempt. They all involve some sort of DOS emulation and have either failed during the procedure or I judged the instructions either incomplete or beyond my competence. If you know of any simple, "foolproof" procedure to upgrade with Vx20-104.EXE please help me out. </pre> </blockquote> Seems from the Dell site that you need to create a bootable disk (usb is doable) by formating in windows as system disk (Check the "Make bootable" option). Virtualbox would do or borrow a friends PC. Dell is in bed deep with windows so the "easy" method is borrow a friends PC or go to the library and try. Copy your file to the usb; which being a fat32 format most likely will be readable from your system. Reboot with the disk and run the command: Vx20-104.EXE [filename is the command] and this should launch the program... Double check the the file that it is correct... the one I found, with the info you provided was 3550A11.EXE found at <a class="moz-txt-link-freetext" href="http://www.dell.com/support/home/us/en/19/Drivers/DriversDetails?driverId=N2KW4">http://www.dell.com/support/home/us/en/19/Drivers/DriversDetails?driverId=N2KW4</a> but this is with out the model number of YOUR system. So double check you have the correct file.
