I miss the days when you could do things like connecting the L5 bridges on the surface of the AMD Athlon XP Palomino [0] CPU packaging with a silver trace pen to transform them into fancier SMP multi-socket capable Athlon MPs, e.g. Barton [1]. https://arstechnica.com/civis/threads/how-did-you-unlock-your-palimino.709631/ https://arstechnica.com/civis/threads/how-did-you-unlock-you... Some folks even got this working with only a pencil, haha. Nowadays, silicon designers have found highly effective ways to close off these hacking avenues, with techniques, such as the microscopic, nearly invisible, and as parent post mentions, totally inaccessible e-fuses.
