Per Dell Support Center the current BIOS version for the E521 is 1.1.11. I have 1.1.6, but when I try to update I get the "unsupported system" error message. Do I have to install all incremental versions in sequence?
I think that is incorrect. The compatibility section of the bios says it is for the C521? In fact, all of the Bios files under E521 are actually for the C521. I will escalate this.
