Vista Tutorial - BIOS Update Problem

Hey all, I am trying to install Vista on a Dell D600 laptop. I am having a
problem and I was trying to update the Bios from version 8 to 13.

The installation instructions say I should be able to run from the desktop,
however I get a "Program Access Denied" Please make sure that you are logged
in as administrator"

I am a Domain Admin on my network, went as far as to make me an local admin,
then even tried logging into the administrator account on the PC and I still
get the same error.

I tried making a boot disc as well, twice even. But the system just boots to
a blinking line prompt and will not accept user input.

Anyone have any thoughts?

Thanks,

John
