The older .ROM BIOS comes with the Asus Sabertooth X79 and isn’t compatible with your Xeon E5-2650 CPU. The support site lists BIOS version 4502 as required, but only shows BIOS 1203 as available. It mentions a .cap BIOS file in the driver section, though no converter tool appears to exist. Since the system hasn’t updated yet, you might want to check other archives or contact Asus support for removal reasons.

You need to erase the specific ROM file first, which will allow you to install the newest BIOS files afterward. As mentioned, this modifies your system's BIOS configuration.
