The Aptio bios supplied with the Inspiron 620 MT is a barebones affair, giving control over the basic options and nothing more. We can see that the hard drive is the ‘ST31000524AS' – better known as the 1TB Seagate Barracuda, which spins at 7,200 rpm.
No overclocking options, and not much in place for the ‘enthusiast' user. But again, for the target ‘mainstream' audience this is to be expected.
