Sorry, this isn't correct. These icons are not in ROM. For example, the
disk icon is in the driver code that resides in the HD Setup application.
To change this icon, do a hex search for part of the icon. Simply replace
the inline-stored icon and mask bitmaps with your own. (The icon is not
stored as a resource, making it more difficult to change, it's in a CODE
resource.)

The Mac icon that displayes in the welcome box is stored as a resource, and
has always been. It is easily replacable. The text can also be changed, but
has a maximum length.
