I have an Dell Optiplex 990 that I am trying to get a Slic 2.3 into. I downloaded the Bios .exe updater from Dell and used Pheonix tool 2.56 to add the Slic. That was successful but it gave me a .hdr file as an output. The original Dell updater exe has no command line option to specify a bios file to flash with. Can someone point in the direction to get this .hdr flashed? Is there a utility to flash this bios? Thanks
